    Two questions about an European STi

    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.
    Thanks,
    Evgeny

    Hi mate, i used to have the impreza P1 2000 model. basically the prodrive exhaust is a stainless steel exhaust system which was added for power gains but its not loud at all.

    You should probably check the prodrive site. If it is a Prodrive "kit", it would be hard to say what was done.

    As far as I remember, the P1 Prodrive was only for the year 2000. The next Euro spec Prodrive was for 2004, so maybe that is what you have? If so, it is very rare. Is it an light-ice blue color? It would have Prodrive wheels, springs, and exhaust. Quite the monster too (something like 315 HP and 310 ft-lb torque), if this is what you have. Got any pics?

    Since it has a HF cat in it, it likely includes a new down pipe. Only way to tell would be to take the heat shields off and look.

    As for the turbo, I can't remember the exact model, but I'm pretty sure it is a twin-scroll, similiar to a TD04 but flowing a bit higher. Good turbo regardless.
