Hi how are you? I coulnīt wait and I just bought the STI 2011 Sedan.
Do you recomend the new SPT exhaust system?
How many extra horsepower do you get?
I donīt want to loose the waranty, I really like the sound of the SPT ( not to loud), is there another aftermarket exhaust system with more horesepower and same sound as the SPT?
Thank you for your help
