I have been explained that my R32 gtst has a cat-back exhaust (Installed by previous owner).
I dont mind it, it sounds pretty good!
But then i've been told that fitting a 3 inch exhaust turbo-back, is going to give me a better, deeper sound and more kw's.
Is it worth the money to go change everything? And how much more power would I be looking at?
Cheers
