ive got a prodrive rear box, center pipe and down pipe with cat, and ive just been to a subaru dealer enquiring about costs to change them over. he was quite reticent about doing it, saying without the ppp remap of the ecu, its possible that the car wouldnt run properly. has anybody changed thgere exhaust without problems? bit worried about doing it now...
any advice appreciated

 

anyone....?

 

Yes i did it for about 3 months on MY02 Sti no probs at all, even fitted it myself! Have now got it re-mapped and even better
