Hey all, I'm new to the forum so this is my first post :p. Im the fairly new owner of a black 2007 G6 GT convertible and so far I've blacked out all of the exterior lights, debadged it, painted the rims black and blacked out the red emblem on the front. My next thought is an exhaust system but I can't get myself to shell out 6-700 for a catback, I'd rather put together my own SO...

I like the sound of the Flowmaster Super 44 muffler, my question is if I weld one in place to go into dual exits what would I have to purchase to allow that, just an aftermarket valence? Also, I'd like to ditch the resonator(s?) So what size pipe would I need to fill in for them, is) diameter and length etc. Any help would be appreciated and I'd like to hear peoples input about other possibly better options. Thanks! =]

you can buy a dual valance off any gm website but there not cheap. you can keep an eye out on ebay but its a tough find. some people cut out there own valance. and as for the pipe size, the stock pipe size is 2.25'' but if you want some performance out of your exhaust upgrade to 2.5'' all the way from the flex pipe. any bigger and you might run into issues loosing back-pressure

A lot of people swap out the resonator for a glasspack. Without it is said to sound raspy. I would look on youtube for sound clips with and without resonators.

Ok so say I buy the muffler. What inlet/outlet placement and sizing do I want? And with the glass packs, what size and what length?

its doesnt really matter what muffler you buy because your exhaust is going to be constom. most people either use two single in/single out mufflers from a y pipe or one single in/dual out muffler. i have the single in dual out and as for the glass pack it doesnt matter on that either, it whatever you like. your stock resonator is like 2 1/2 feet long so you can buy whatever size you like.

I used a 24" Cherry Bomb in place of the old resonator.

Nah the overpriced parts are the really small ones with moving parts that often break because they're made from flimsy plastic....

OK so say I were to upgrade the piping to 2.5", replace the res with a cherry bomb glass pack and replace the muffler with a single in dual out flow master super 40... can I get a straight blunt answer about EXACTLY what I'd need to buy? Hoping to order asap and I've been trying to do some research and I'm just getting frustrated haha. Install isn't a problem

You need the cherry bomb, the flow master, and depending on the install, hangers for the new muffler, piping (and bends), a new coupler to attach to the flex tube at the front, and probably two new exhaust tips. If you don't want to cut you're existing valance, you'll need a new dual valance. If you want to stick with an easier cost and install, just keep the stock 2.25" piping and just replace the resonator and muffler, and add the two new tips. Are you looking for part numbers and or links for the parts?

That would be awesome actually but don't worry about it if its a lot of trouble. If I can keep it under $300 I'd upgrade all of it but I have a feeling that won't happen lol

If you are paying for the install, I'd stick with the stock pipes for now and just replace the rez, muffler and tips. I got all my parts for less than 200 but spent another couple hundred on the install.

I'll try to find some part links later when I get home from work.
