hey all ive had my wrx sti uk a few months now and still standard.probably going for a ecutek remap as the simtek is a bit pricey,but what other mods
wud you all recommend that are worthwhile for bhp/torque and general
performance improvement?i know you will all be talking from experience
cheers matteus

 

Full decat (or sports-cat if you want to save the planet! ) exhaust system - £600-£900. This would then make the remap worth while.

 

Your not going to see anything drastic without a remap, get a full decat, sti panel filter, larger turbo and a remap, and off she'll go

 

What year of Sti do you have mate ?

 

i take it that its a newage sti saying its uk spec?
walbro 255 fuel pump,k&n panel filter,decat/sports cat downpipe,remove second cat,upgraded backbox and a remap should see you around 330-340bhp normally...if its the 2ltr engine
have a look on andy forrest's website,all the info you need on there.
