I have been thinking to get a whole new exhaust system for my 997tt, with an ecu upgrade, approximately to 550-560 hp.
I'm doing some research for lots of brands and i now got 3 selections left to choice. Which one would you choose? You can say any other brands if you tell the reason :P And I also would appreciate any experiences and feedbacks about any of those systems!
here are some videos that i've found in youtube and from those videos, i'm leaning a little bit towards to fvd race type exhaust, but i haven't decided yet, it's important to me to read some experiences and
