I'm the proud owner of a slightly used 2009 GXP with a 6speed manual. I'm looking for more power with better mileage. What aftermarket exhaust sytem would you recommend to help achieve this?
glass package deffinately
I waited for ever to get a GXP but they never came to Canada, so I bought a GT and put some Kooks headers and 3 inch pipes. People will not stop complimenting me on the great sound (the performance is also outstanding)
