What option's for tuning a my03 sti type uk, thought of PPP, but saw a 03 STI at end of city bypass and had very nice exhaust ,much nicer than prodrive???.also saw/ heard sti at sidc /knockhill last sat ,sounded like fitted with different BOV / DUMP VALVE v/nice . have been thinking this one over for far to long...

 

was the sti at sidc mine ??

go get yourself an exhaust, depends on what note your after, i see my good friend opelcorsa is selling his back box which wont affect your warranty

 

Vary out side of the factory fitted items and subaru options and they can invalidate your warranty (or parts there of!)
The PPP exhaust is designed to be fairly quiet whilst driving around town and on the motorways, but get above 4k rpm and you notice a little difference
Your safest option is the PPP, you retain your warranty with this, but there are other routes you can take (ecutek) for instance but look at the cost of a new engine if things go wrong.... (im not saying they do or will but uk sti's have been known to det.... even remapped ones!)
