While in my current position, it looks as if I may have to go with a dual exhuast conversion on my 07 V6. Not that it's a bad thing or anything like that, but I just have a few questions about the install. First off, a stock GT H-pipe should fit in nice and snug, correct? Also, does anybody have any experience installing an H-pipe, X-pipe, or any other aftermarket pipes; I need to know how hard it is swapping the Y out for the H. I really cannot justify paying a shop to do work in a day for what I can do for free and take less time, not to mention feel accomplished. Thanks guys.
