It's definitely possible hndah8r. I never thought about that. The custom exhaust probably modified the back pressure for a performance decrease.
Except for the piping. That's the key.I just don't see how my performance would be that bad because its almost the same set up.
Yes. around 680-700 dollars shipped. I think the exhaust sounds perfect with the resonator. Truthfully, after reading all this discussion about exhaust, I would only buy either a Magnaflow or GT-R exhaust for performance reasons. I could not imagine sacrificing performance for sound. I love my torque.so all together i would have to pay around 700?
i have heard both the 80 series fllowmaster with and without the res and with out sounds the deepest and gives no rice sound thats what i am looking for. here are the the two vids i saw
Flowmaster doesn't make a catback system for the G6.why not flowmaster?
