Hey guys,
if you dont already know i own a performance and body shop in NJ. I am in the midst of building a custom exhaust for my GXP, but what i want to know is if anyone would be interested in buying a bolt on exhaust system for their car... Let me know.

Do you have pics of the system? What is your selling price? Do you ship outside of New Jersey?

to answer your questions....
1) no pics yet...still in development
2) would probably sell around 400-500 price range
3) surely...all parts needed would be included in package
installation not included :)

i plan on using magnaflow products with full stainless stell 2.5" piping.
let me know any additional ideas you guys have too... i can see what i can do with them.

What tips are you planning to use? 4" polished tips would look nice.:cool:

actually i plan on using 4" x 7.5" magnaflow polished tips lol

Here is my system.

Kman is this system built yours or from Magniflow? I check Magniflow site with no help with it. I want to get one please help.

ok guys here is the deal. I have put together a system somewhat like the gtr system but I think better. It will sell for 499.99 plus shipping. It uses a single magnaflow muffler and 2 magnaflow tips. All 2.5" piping needed is included. If anyone is interested let me know. Pictures to come soon...

by the way if you live near or close to union nj we would be more than happy for you to come pick up your system so you don't have to pay shipping And we would also be happy to Installnit if you need. With your purchase you also recieve 2 free mv motoring decals with choice of color.

what kind of motor is under the g6 video clip?

when do u think ull have pics? and will this work with a 3.5L V6 4 door let me know

im still in the process of fabricating the piping since im using 3" for my car its a little harder...making the pipe for the other cars should be easy...once its done ill post the pics...probably by the end of this week

Kman is this system built yours or from Magniflow? I check Magniflow site with no help with it. I want to get one please help.It was custom built.

Hey Big Mike since you own a stop question? Does that sys work on a 06 Malibu Maxx? there are not many parts for my car but i know that The motor in the 06 G6 GT and mine are the same. Second question: if i got a hold of the new 6 speed tranny would it bolt onto my engine cause 6 speeds sound a lot better than the 4 i got. I know the cold wouldnt be cheap but a lot cheaper if it did work than buying a new car I think cause i love my maxx.

need a system for G6 GT

I have a 3.5 G6 GT 4door. I live in Newark, NJ so i live real close to your shop. Do you know of a way to convert the rear bumper into a dual exahust? My car only has the single hole :(

If I buy a G6, I'll look you up later on.

I had dual 40series flow masters on my thunderbird, and had a custom built dual magnaflow system on my trailblazer. I want to put exhaust on the car and think it could sound good but I am scared that going with magnaflow would give it that honda coffee can sound. The setup i had on my Trailblazer was nice, but I guess I was use to the dual 40-series flowmaster from my other car adn really like that deep tone. Anyone know of anybody who has used flowmasters on a G6 GXP, or a G6 in general? There is a guy who owns a shop near us and he bends all of his own pipes, my boss at the garage where I work got me a good deal on the trailblazer so I would probably use him, just trying to see if i can hear what it sounds like before I go and spend the money on it.

i saw a guy on youtube who had a gt and he took the rear 2 hole piece off a gtp and put on his gt and ran duals so i am now lookin for a gtp valance for my car so i can do it i have a 3.5 g6 gt 4door also so if anybody knows where one is or wants to get rid of one tell me please

Has anyone put anything on the gxp yet????/

i did a full exhaust and custom intake on my gxp...didnt take any pics yet though

if you take any pics let me know, i really wanna see that car .

its similar to the gtr exhaust but i did it for a fraction of the cost since i did it myself...the intake is just an intake nothing special

heyy whats up man i just got an 06 g6 gtp coupe and i wanna put and exhaust on it but i cant find one the one that you put onto urs is sickk where did u find it?

how much? and do you use magnaflow? and is it dual right back?
a

is this a cat back system your making, and will it have the dual mufflers like in your picture or one muffle like you said later in this thread, cause I'd rather the dual, I've seen the one that Gm makes with the single muffler and I don't see the flow advantage really. Also if it is a cat back system, is it a botl on one, and what guarantee's do I have that it won't affect my warranty?

I Just Got My G6 Gtp And Ready To Make It Sound Mean.. Money Is Not A Huge Option.. Holla At Me With Some Suggestions!

Alright Dallas!!! Soon us Texans will take over!!

Sam makes the GT-R exchaust up there around Dallas somewheres.
Hollar at him. http://www.classic4performance.com/

3.6?? now you need an intake!

I have an 07 g6 v6 that i would love to add a custom dual exhaust too. How much would it be?

Here are some pics of my exhaust system just recently installed.

That looks so nice. about how much did that cost you and would it work for a 2 door gt 06?

You can buy a new rear fascia with two out lets for about $110 bucks at the dealer... from what i have heard its an easy install

That looks so nice. about how much did that cost you and would it work for a 2 door gt 06?
I ordered the mufflers and tips online, and then told a guy what i wanted ,and he made it for me; total job just shy $600. But its dual from cat back and sounds F**KIN AWESOME!!! It is on my 06 gtp coupe. The GT needs the dual outlet body kit.

hey i would like to buy exhaust from you if i could hear what it sounds like first and how much you would charge

That Vid Was Nice Man! Kudos On That Exhuast!!$$$$$$$$$$$$$$$$

overpost

Here is my system.

http://i37.photobucket.com/albums/e95/KeithGTP/PONTIACG6EXHAUST5MediumWebview.jpg

Sound better then anything ive heard....NO RICE IN THERE! Let me know how much for same dual muffler setup for my 06 G6-GTP Auto Sedan. And i will prob do that spring lower set in this furum(Sprint co. G6 05-07 #3404 1.75/1.75 ) And get crabs...but thats ok my ball's are shaved.......You the man!

Just got a g6 4 door and love the look and sound of that exhaust. how much for the system for my car? Plus for those of you looking for a rear valance go to gmpartsdirect.com. part number 22712778 for the valance.

Here is a clip of my exhaust.

CAL, Do you have pics of the exhaust system up front. Need to see how the pipes come out of the cat's and go to duels.

I am having problems with the muffler places where I live. I showed them a picture of your duels but they wanted to see the front.

Don't ask why. Been to 3 places and they all say the same thing.

So if you have other pics it would greatly be a appreciated.

I don't like the massive amounts of rollover on all the vids i've seen so far. To me, it just doesn't sound right. You can't go super loud while keeping the rollover at bay, but I'd rather have my exhaust sound really nice rather than having it loud. Just my opinion.

No pics showing the front, sorry. It is just a y-pipe coming off the flange from the cats and duals out the back like the pic shows. I would think with that pic they would be able to duplicate it because the guy who did mine said that was the hard part! If you want I suppose I could try to get you a pic, let me know.

getting your exhaust exactly the same as someone else is okay, but all you really need to know is the width of pipe he used and the resonators/mufflers that he used. if you bend the pipes differently or put the mufflers in different spots, it will still sound pretty much the same...and you won't be able to really tell if it does or not unless you go to his house and sit them right next to each other...every camera will record sound slightly different...not to mention you can be a video ninja and change the way it sounds with a few tweaks, too...you could have the shittiest sounding exhaust and make it sound amazing with an audio editing program.

Not trying to have the exact exhaust. I am however, trying to prove to some of these bone heads where I live that it can be done.

Got really pissed yesterday when the guy at Haggard Automotive in Roscoe Illinois laughed and asked why I wanted to get a custom exhaust on a car like that, like its any of his business any way. Ya it's not a 700 HP supercharged Corvette, but it is mine and money is money. I wanted to teabag 'em. Dork probably drives a Hyundai.

I tried to get a pic for you, but it will have to be on a lift to get a good one. Hope you have better luck then what you have had, and my description helps. Are you trying to prove duals can be done? All the way up or like mine? I saw some where someone did dual all the way with cherry bombs about where the resonators are and that was it (didn't sound very good, thats why I had mine done the way I did).

Ya I printed a couple of pics of yours its just getting some one to do it. Seems like these day people should be going out of their way to get business.

I saw the guy with sherry bombs, did not hear it run though, figured it would sound crappy.

I think the roll back what Fuzz was talking about would be a bit much for me. Flow master makes resonator type through pipes. I saw a video of a guy who had an impala SS with those type of resonators and flowmaster 40 series. Sounded good I thought but it was a youtube video...

Hey I got a 2008 G6 GT coupe 3.5L V6 Single exhaust, anyone know what I should do to get a dual and as far as your custom built ones I am very interested just hit me up.

Ok, found a muffler shop willing to do it my exhaust.

They recommended that I use Dynomax ultra flo X and not flowmasters. They are a flow-master dealer too...lol. They said the roll back on V6's are pretty "poppy" without a resonator just as FUZZ indicated. Flo X would sound very deep with little roll back. They said I probably would not need additional mufflers as the X pipe its self acts as a resonator and the muffler has sound deadening built in. Its like a 2 in one thing.

I opted not to go from the Y pipe flange to true duals. I am having the Y pipe customized with 2 flanges for true duels.

I want to listen to it before they install the full exhaust though.

What do you all think? Good Idea Bad ??

Here is a link to the FLO X

http://www.dynomax.com/mufflers.php?muffler=ultraflox

get a flow through where the res was or it will be raspy....

Yeah, I wouldnt go with the FLowmasters, they sound like "tin cans". I would go with either Magnaflow Mufflers or I have heard good things about the Dynomax Mufflers, supposed to be deep sounds similar to the Magnaflow Mufflers. Glad you found an exhaust shop willing to take your money! Pics and sound clips will be a must!

Ya I just called the local Muffler shop and they laughed when I asked about the Dynomax...he said if you want real performance and real sound go magnaflow.

Did not know magnaflow made a X pipe muffler.

Should get my car back tomorrow.

I will post pics.

Awesome!!! I can not wait to see it!!!

trying to upload pics and vid but I cant seem to. Keep getting a message about a security token.

I can def relate I had a V6 Camaro and I put a flowmaster dual exhaust system only on the rear and made my 3.4 li sound like a V8 until about 3500 rpms My goal is to install the same exhaust on my G6 and have a nice growl kinda like this clip
I sure hope I can fit it under there...:)

http://www.youtube.com/watch?v=cXJUbNYkAWo

I'm trying to fit an 80 series flowmaster muffler in my G6 Sedan it has one 3 in inlet and dual 2.5 outlets on bothsides so it should be easy to bend 90 degree angles and have them run out the lower valance any ideas how to run the inlet pipe around the muffler to mate it with the exhaust pipe?? also any good ideas on how to adapt the 2 1/4 pipe to a 3 in???

That sounds GREAT Jetmech!!!! I can not wait to see pics!!! What really matters is if you like it or not? From the back it looks like they did an awesome job hanging it up under there!

Thanks,

Having a strange noise in exhaust. Sort of a squeal mixed with rattle. Going to have it looked at by exhaust shop. Crawled under it but couldn't figure it out, nothing seems to be loose.

Very nice, hope that noise is an easy fix! So, I'm guessing you spent less than me on it; what did you end up spending when it was all done? Although with the fabing of the front pipe you might have still spent as much?

I would like to have a exhaust system installed, that has the deep growl for my 06 g6 gtp sedan.. I hate the crazy A$$ popping shiz.. would someone direct me on where (On the internet) or what to request at a performance exhaust business? I wanna make sure I'm not taken advantage of, being a woman and all. and of course I want to have this done secretly for my husband. :D


Thanks!

I dunno man, 6 of 1 half dozen of the other. I can't remember what the kits cost online but I paid $550 for custom. That included the muffler that my exhaust guy got cheaper than I could online. 2.5" 100% stainless. I have never heard a GTR in person and I can't really tell the difference listening to the videos. I do know it does not have a tinny pop on roll back just a growl. I have bad hearing anyway for 13 years building and testing jet engines so... I get allot of compliments on it. Another customer at the exhaust shop said it did not sound like a V6. I don't think it sounds like a v8 but maybe a V6 and a half...lol.

I think the X pipe has something to do with the different sound.

I seems to really make a difference at higher RPM's I think I lost a bit of low end torque. Driving on the HWY at 65 drop into 3rd and nail it, sets you back in the seat pretty good.

Did a dashhawk 0-60 it was 5.9...not sure how accurate it is. I had allot of wheel spin and hop. I wish I could get rid of that hop as well.

Not sure what that noise is in the exhaust. It almost sounds like air rushing through pipe but I have never heard anything like that before. Sort of a high frequency rattle.

Took it to the shop but exhaust guy could not put his finger on it, it was on saturday so not much time to look at it. Will take it up there pretty soon on a weekday if I get the time. It's really irritating.

I got this one and have been happy with it. Its a bolt on but they sell out all the time and there is usually a waiting list.
Clicky here (http://classic4performance.com/)

Not to insult anyone!!! And I mean it!! I have heard all the clips GT-R and others and the only ont that sounds decent(without that tin rumble at end note..like a germ car) is a true dual i saw on here months back...gotta find it...all those single pipe muffler to dual tips dont do much for HP gain...And I have a NHRA 8 sec license....But I am also looking for a upgrade like everyone else for most bang for buck...sorry Lampoon..not banging on you...only my opinion every will do what they thinks best of course.

No skin off my nose. Get what you want. ;)

Also, increasing your pipe size coupled w/a flow through muffler sans the resonator
does indeed do something...but you know what they say about opinions. :D

So I have delayed on exhaust for my 3.9L GTP for the simple reason that I hate that I MUST RESEARCH FIRST, ok so I was going to buy the GTR but then heard others online that sounded to my believe much better. I now still have stock exhaust so I was wondering if any of you outhere with aftermarket exhaust lived on northern Cali or bay area? If you do then email me at bayareastuner@att.net so I can hear your exhaust please

It was custom built.

what brand of muffler did you use? did you just buy different lengths of pipes to use?

I own a 2006 gtp sedan (the v6 3.9l). would ur system fit? how much/long(time) to install?

i am interested in a magna flow exhaust for my 3.5 g6 gt

I have been waiting for someone with a real dual set...but everyone runs from one pipe and then splits it. A TRUE dual is a seperate pipe from each exhaust manifold all the way back with seperate catalitic converters and mufflers for each side....so 2 pipes from one y pipe.....Mmmmm no! Not dual! Sorry. If someone out there has a set of headders(even off manifolds)... and did a real run...let me know..im interested in dual exhaust...not a catback setup like all the ones on here.....:D

Well you can dual it out all you like but unless you magically add two more cylinders it's still going to sound...well, not as good as a V8 does :-p

Well you can dual it out all you like but unless you magically add two more cylinders it's still going to sound...well, not as good as a V8 does :-p

Amen....will never sound like my 67 Coronet or any 8cyl...but i also want all the bang for the buck i can get from rides.....So i found a set of headders(Pace) shitty company on the foodcain of headders...but dont see any other tuned ones for a 3.9....;)

I have a TRUE DUAL system with x pipe muffler. The X pipe is built into the muffler itself. Guy named calsgtp on here has duals as well. Click on the photos under my name I have pics there. Doesn't sound like a v8 but I get allot of compliments.

What's the exact name for the mufflers you used? And do you you have anymore pictures of the system under your car?

Magnaflow 12658 muffler, has x pipe built in.

No other pics under the car, sorry. I guess I will have to take a few, had allot of people ask me for more.

I checked for that parts number on magnaflow and got nothing.I'm looking everywhere for one.are you sure that's the part number?

Jetmech,

I think we all need to hear how that thing sounds revving above 3k rpms. Can you take a video and open it up, I would love to hear the top note that system will put out and determine how much my neighbors will enjoy it at 2am ;)

Jetmech,

Well...that is why I did not rev it hard, I live in a condo complex. So I don't want my neighbors doing that to me at 2 am...

the sound is awesome!

I am going to go to the exhaust shop I used to do some work at to get his opinion on what pipe sizes / mufflers I should use if I were to run true duals on my car. Being the GTP it already has high flow cats so I should just be able to cut the pipe about a foot down from those and start from there. I will most likely just run the same OD as the cats trying to keep my bends slight. I was thinking about keeping the mufflers in the front of the car where the resignator is. But I will see what he thinks. Any suggestions?

Im not sold that a true dual will add anything to it.
These arnt racecars.

I am skeptical also, prolly the only thing it will do is rob my low end torque... I have often heard that you can get more power out of a single muffler rather than two. Although two does look nice we will have to wait and see what he says. We shall see what the story is friday when I get out of this hell hole (Labrador, Canada -30 celcius) and back home.

Did I read somewhere that Borla may be coming out with a dual catback in mid March?

It was custom built.

whats the parts number on those mufflers? are they magnaflow.

OK

Here is a drive by.

Had allot of people ask me to rev it to 10 grand, wake the neighbor up, do a burn out or blow my engine. So here it is....not 10 grand and I did not wake the neighbors or blow my engine...sorry.

http://www.youtube.com/watch?v=rxi8hb8zlYA

great sounding exhaust you have there Jet* I was almost sold on turbo borlas, but have not heard them on a G6 3.9L and my budget isn't that friendly either to be the first. Anyways I was wondering how ur low end torque was? did u maintain proper pressure or completely lost low end? The reason I ask is because I need a muffler soon I am running straights right now and have no low end but damn at high speed high rpms the G6 flys....

Thanks.

I did not really notice a lack of low end torque. It did make a huge difference at 3K and above. I can do hellatious burnouts through second so I really don't have a problem with torque off the line.

My setup is a bit different than others here as I run one muffler dual in dual out with an X pipe built in and it's true cat back duals, so no Y pipe. The muffler shop guy is the one who actually sold me on the idea and it worked.
Got it all done for $550, that included 100% stainless exhaust. 50/50 stainless would be considerably cheaper.

Again, opening up your exhaust does not cause your engine to loose torque it just changes in the RPM range. That is why your car pulls harder at higher RPM's.

Well said Jet. I too am having the same setup installed while I am away for work. All stainless 2.5" duals from the cats. I also agree that it is not going to rob any torque from me, hell I have to feather it up through first now as it is. :)

sounds good jetmech

Again, opening up your exhaust does not cause your engine to loose torque it just changes in the RPM range. That is why your car pulls harder at higher RPM's.

RPM range is altered by : Camshaft duration/lift profile, intake manifold design and compression ratio.
The reason it feels like it's pulling harder in the higher rpms, is because of the lost of torque in the lower rpms.

The pulling harder feel is from the velocity catching up to the volume that the higher rpms creates.

RPM range is altered by : Camshaft duration/lift profile, intake manifold design and compression ratio.
The reason it feels like it's pulling harder in the higher rpms, is because of the lost of torque in the lower rpms.

You are right but not completely.

You left out the fact that changing the exhaust profile changes the power band as well. Also the bore, stroke, ignition and cam timing of an engine has a major factor in the TQ and HP curve. Since we are dealing with small bore and stroke here RPM is your friend, large stroke engine it is not.

"The pulling harder feel is from the velocity catching up to the volume that the higher rpms creates".

I am not certain what this statement means. The venturi effect states that volume and pressure are opposite of velocity. When velocity increases pressure and volume decreases (when a fluid goes through a venturi or some type of clean restriction). When volume and pressure are closely respective of velocity then there is no venturi effect. This will mean zero restriction and terminal velocity. This is aerodynamics 101.

It is a fact though, that depending where a restriction occurs closer to or further away from the pressure source. The Delta Pressure will increase or decrease faster or slower respectively. This results in a change in power band in an internal combustion engine. This is why we increase or decrease our header collector lengths. This is a proven fact.

Back pressure will kill the HP and TQ at the higher RPM range that is a fact.

I believe the point that you are trying to make is that dual exhaust or less restrictive exhaust will kill you low end torque and not increase torque or HP at higher RPM ranges.

Is this your point?

"The reason it feels like it's pulling harder in the higher rpms, is because of the lost of torque in the lower rpms."

This is BS here.

sounds good jetmech

Thanks man, I do get allot of compliments and people inquiring on this exhaust that is why I posted a vid of a drive by.

I think the X pipe muffler from Magnaflow is the way to go.

I was just reading this on my way to air airport and had to comment on that one. "The extra torque you feel is because you have lost your low end torque" I assume he is saying your car has actually hasn't gained anything which would be virtually impossible unless you changed your tubing to garden hose?

I also have a 3.9 and I know there is a tremendous amount of back pressure as when in the top of a gear and letting off a bit to go around a corner the exhaust cracks like an engine brake on a semi.

I too am having A dual 2.5" system the same as jetmechs installed. I will post a video when I get back from Labrador in 3 - 4 weeks. Maybe ill have a new ecm, and megan racing coils on by then too! :)

PS. Never teach your girlfriend how to drive a stick on an RX-8, its really hard on the neck, and yes for those wondering no they don't have any torque, and are no match for a G6 w a 3.9

Megan racing coils? Did not know about this. Been looking for new ignition components.

You got a link?

Hows many hours have you spent on an engine dyno? How about a chassis dyno?

I won't get into a debate on this forum. That was not my intention, it was simply to set the record straight. BTW, based on your statements a car making 600 whp, should have 6" diameter dual pipes, and there's a very good reason why they don't.

The G6 is not a dragster.

Not sure who made the statement regarding 6" pipe on 600hp engine but it wasn't me. So get your facts straight sunshine.

And ya..I have thousands of hours dynoing aircraft engines what about you?

Where is your papers on mechanical physics that you wrote? I'd like to see your work.

If you don't want a debate the stop posting idiotic comments about peoples mods.

If you want to go pump GTR exhaust or whatever you are selling then do it in a constructive way. Don't try to slam someone's ideas or accomplishments. especially when you are a laymen at best regarding the issues.

Well, jetmech, I like the sound. I might have to look into it for my 3.6 .... even though I keep telling myself to leave it stock it is hard to resist. I think I need to do a wams, crabs and an exhaust like yours :-P

Thanks for the compliment.

I don't have tune yet. I would like to get one. It's a toss up between a WAMS or getting dyno tuned. I am saving to buy a house right now and pay for 3 tickets from Australia, so I am trying to save every penny you know.

I may just get a WAMS and be done with it. It's cheaper, easier and takes less time. And I have not heard any complaints about it. I also need new tires. I don't really drive the car much, only on weekends. Try to keep it out of the snow and stuff. Alex was mentioning Megan racing coils. I think I will look into that as well.

I thought you were talking about ignition coils..The link was for struts.....OOPS

My bad.

Here is my system.

i wanna get this exhaust system right here its from megaflow right
where can i buy it ???

Hey guys, just got my G6 2006 GTP coupe. Loving the car so far, I have just installed K&N air intake system, I'm looking to get the right Exhaust system, I'm needing one that supports the dual exhaust of GTP. Do you guys have any suggestions on what I should order. I want it to be agressive, as I'm doing alot of performance upgrades soon. Online I have seen the GTR on youtube and other ones that use Magnaflow. Any suggestions of the best one to get for most robust sound and best performance?

Im also trying to find the best exhaust for my 2006 gtp coupe, just got the car love it. I have had new air intake system K&N put in. I am wanting to make sure whatever I get sounds like true sports car and dont want to get the wrong exhaust system, does anyone have any reccomendations for best exhaust in terms of performance and sound out there is dual exhaust to match GTP.

Thanks guys.

Kmans exhaust was custom made.

I have the Classic Performance GT-R and am very happy with it.
:beer:

Pretty much all the dual outlet systems are custom made, except for the GT-R system. So, if you dont want that one, you will need to find an exhaust shop and talk to them about what you want to do. I believe that you should use Magnaflow Mufflers (similar to mine) or Muffler (similar to jetmech). There are a lot of systems on You tube that you can listen to, jetmech and mine are on there too. And of course after your done you have to post yours.

ill be getting mine soon but first im buying a body kit for mine to make the lower look and to have the dual ehaust in the bak

Today, I put my brand new rear lower valance on for dual exhaust. I really could use some help/advice because I can't make up my mind for a exhaust. I noticed a lot of G6 owners are using the GT-R dual exhaust. However, I'm not going to spend $700.00 for this system because its slip on and there isn't much to it.

I'm very picky when it comes to my car. I DON'T want that ricer/import/fart/coffee can noise. I also don't want a loud v8 noise either. I want something nice, sporty, and when you get on it you can hear it noise. Any ideas or suggestions?

I've looked up many videos and every car sounds different. Even on the GT-R exhaust. I'm not sure if this is due to some people having intakes, resonator taken out, etc. but I can't find one that I actually will like. (I DON'T WANT TO REGRET IT)

For the GT-R exhaust does anyone know what kind of muffler that is or series? Please let me know fellas. I would greatly appreciate it. Also, send some links my way if you think it would help.

Dillon :cool:

I have the single exit and love the magnafow no rasp and no fart can sound just a nice low rumble and i can cruise around and here almost nothing.. but th ats what i was looking for.

If i was in your situation i would do something similar to Jetmech i love the sound his makes just like mine But IMO a bit better

I recommend you attend a G6 meet in your state and see and hear what others have.

Yes, and as you can see from the regional clubs section there's pretty much weekly ones going on all around the country :D








Oh wait a minute...:confused::(

here is a review on the GT-R that a guy posted last week:
clicky here (http://www.g6performance.com/phpBB3/viewtopic.php?f=28&t=31821)

Checked out the review,thanks Lampoon,one question he spoke of "you can feel the right exhaust valve opening".Does the muffler have one normally closed uotlet that opens on acceleration? As this is one of the mods I want to do I'm curious.

Yeah thats the way its designed, for backpressure. I got my GT-R about three weeks ago. This thing is BAD ASS! I have no regrets. Although i wasnt that happy with the clamps. So I Just got some that I like better and now im:D

Thanks for the info guys. I think I will be buying the GT-R exhaust. If this many people really like it than I'm sold. I just really hope it doesn't sound ricer/fart can. I want to stay far away from that. I'll keep everyone updated on what I do and get.

Dillon :cool:

Which clamps did you go with???

I went with this Walker #33226 Lap Joint Clamp. Got them from summit racing for 9 bucks a piece. Perfect fit.

http://ecx.images-amazon.com/images/I/4110FMT64DL.jpg

Does anyone know what exhaust/muffler that is? Also, what kind of tips are they and what size? Lastly, whats the size of pipe used? Let me know please.

Dillon :cool:

its a Magnaflow muffler. i have the model number at home. but regardless GT-R modifies the muffler for perforamnce. so even if you were to order the same one it would be different. its 2-1/2 Manderal bent pipe and i think they are 4" tips but not sure.

Sounds right on all accounts :)

ive heard good reviews on the GT-R exhaust system (http://www.partstrain.com/ShopByDepartment/Exhaust), i just want to know if it has the direct fit type for easier installation, and have any of you guys encountered any complications in installing the system?

What year and model (coupe,sedan,convertible) do you have?

Here are some pics of my exhaust system just recently installed.









you should put a x-pipe in there. It will sound better and you will get more power.:D

Where is your shop, i live right nest to union. Can i hear the system in person?

I live right next to union, do u think i can hear the exhaust in person?

hey man, where is your shop? I live right nest to union and i was wondering if i could hear the exhaust in person?

i definitly want one of your exhausts if your still making them and ill be more than happy to come down and pick it up

Is this exhaust still available? If so how much for exhaust and install labor?

Thanks

has anyone ever used magnaflow glass packs in a custom job before? i used a glass pack muffler on my last car and loved it. i was wondering if anyone has any experience using them in a system on a 06 g6 gtp (duals of course)

I didnt know they made a glasspack. Ive used their flow through muffler on my second exhaust as a resonator replacement, probably not what your looking for.

yeah, the definitely make them because i had one on my eclipse. the glass pack muffler sounded real nice cuz i had a v6 eclipse and it made it nice and deep sounding. i was kinda going for a nice deep rumble for my gtp but im not sure how duel glass packs would sound on this car as apposed to other exhausts
