Hi, has anyone fitted an After Market Exhaust on the STI yet?

If so, what and what improvements?

PPPMAT

Fitted a prodrive backbox (that you get as part of the ppp). Sounds much better. Goes a little bit better. The slightly stangled feel higher up the rev range has most definately gone though.

I'm told that the gains are minimal, the sound is much improved though

sti03

ok....Im aussie so your lingo is a little confusing to me

what does ppp stand for? and is a backbox a rear muffler?

S.B.

Prodrive Performance Pack

Yes rear silencer/muffler.

just picked up ma new st1, fitted beautiful tsl back box, well made but a little on the large size (4-5 inch) quite a deep bass sound and not as loud as a scoobysport box.anymore system types fitted let me know.

can fitting just a back box loose power ??

You will only have to loose 2 bolts

Litchfield Imports in Cheltenham do a full SS Exhaust system for the MY03 STI for arround £800 + VAT plus fitting...
Does anyone have one of these??
How does it stack up against the Scooby Sport exhaust?
They recon +30bhp and turbo lag reduced by 1000 revs?
BUT
the prodrive pack gives more power & tourqe only above 3000 revs...?
Surely the litchfield deal is a better one?? or am I missing something.
Anyone got any advice??

Sti03,

By replacing the BB you will relief part of the back pressure in the exhaust system. So you can expect some bhp gain... but don't look for 2 digits figures
