I've got an '03 STI 2.0l (European model) with a ProDrive kit.
Here are two questions I've got:
1. I've read alot about up/down pipes and cat. What does my ProDrive kit includes in the exhaust system? If I plan modding the car, should I stay with ProDrive or change to anything?
2. What turbo this car got? I'm almost sure that its a IHI V39 but I aint sure.
