Firstly sorry as I know this has probably been covered plenty of times before, but I'm new to the scooby modding scene and after having my car for a year (2004 STi) Im starting to want more power. From what i've seen so far im currently saving for catback exhaust (afterburner for the burble), decat dp, 3 port solenoid, walbro 255 + remap.

Does this sound like a good start? What sort of bhp could be expected from the above? Also would this still be MOT friendly?

Thanks in advance

 

keep an eye out on here and you'll find a full exhaust system(preferably with a sports cat so its m.o.t freindly, I' had a full milltek for less than £300.

with those others mods you should see 350 with a good map.

Also induction kit ( for the noise) or panel filter

 

Panel filter,
3 port,
Walbro,
Decent de-cat exhaust or at least a sports cat,
Good mapper,
Should see in the region of 340 to 350.

 

Dont sti's have 3ports standard???

 

Thanks for replies - time to start saving i think
