180hp TT Owners Please Note
We are aware that many 180hp FWD and 180Q owners are converting to 225 turbochargers and exhaust systems. Before purchasing any of our TT exhaust components for your conversion, please contact us to discuss your project. The internet may say "it will fit," but our experience proves otherwise. There are distinct differences between the 180FWD, 180Q and 225 stock exhaust systems that many will deny. We have proven these differences and we urge you to contact us before purchasing exhaust parts for your conversion so that we may steer you in the right direction.
