i have a gm performance cat back exhaust and was wondering if anybody has made it a dual exhause like the gt-r and was wondering if i could do it help me out
aahhh! but they do, GM part number:19155028No, they do not dual the GM performance ones for the G6.
So, if you DO have the 3.5L Sorry, won't fit.For Use on 3.6L (LY7) Engine
To be completely honest, I'm not sure if it would or not HOWEVER, I don't know if I would spend $1200 on an exhaust for the G6. Unless you REALLY like GM. I would save the $400 on that and get the GTR. At least you'll know it will for sure fit your G6.but its just a cat back....do you really think its that engine specific?
...oh yeah good question about the engine?
