03 JDM STI Exhaust
Looking at options for light tuning of 03 JDM STI.
It currently has standard JDM STI exhaust/filter and remap for UK fuel.
Was considering high flow cat/changing remainder of exhaust (mid/back box) and ECUTEK remap + green panel filter. Would fuel pump need changing also?
Do not want full decat or hassle of swapping cat come MOT time, hence hi flow cat (TSL Thundercat, or pulsed full system, or would it be better to change just cat and keep remaining STI exhaust backbox/mid sections?)
guessing on 350-360hp??

Your best going for something like a miltek exhaust and sports cat, STi panel filter and no you dont need to upgrade the fuel pump, this is a JDM STi not a uk one
