Got an 03 Sti .. Had it since new and i think its time to do some mods as the warranty is now over.
Considering a full de-cat exhaust system, uprated full pump, air filter or maybe induction kit and a re-map.
My question is it better to go for the tuning packages offered by Powerstation and WRC Tech or is it better to buy your own components and get then fitted with a re-map.
If it is better to buy your own components any recommendations?? Also recommendations on who to fit and re-map. I live in Birmingham so somewhere close to here would be gr8 but am willing to travel if for good skills and knowledge
