Guys after abit of info, i'm looking to remap my03 STI PPP, had it dyno'd and its pushing 288bhp & 305lbs of torque looking to get it round 330bhp, been told that i'll need the centre, downpipe and decat, and induction kit, remap, should get near enough to those figures.
I was wondering how loud is the exhaust going to be, i've already got an afterburner backbox on the car sounds nice not too loud, but has abit of rumble, but i use the car everyday and have some early starts, so don't really want to be annoying my neighbours.

regards

wont be to much louder mate i had one on classic. Center sections ,decats and filters always available 2nd hand on here speak to matty at polepostition. As for mapping i cant recommend jollygreenmonster enough he is the nuts and he can map u at surrey rolling road not to far from london.

 

Ppp sti with remap should make 330bhp without decat or induction.

If you dont want extra noise then get a panel filter like cosworth and remap should see 330bhp.

The 2005 tend to make slightly more upto 350bhp. The ppp sportscat downpipe and exhaust works well.

Decat will see more power but if you dont want the extra noise then no need.

whats the difference engine wise on the later blobs to make more power??

 

Turbo definitely different.

The rest is assumption as not compared side by side but assume cams.

cheers guys for the replies i'll have a look into it!
