revolution 3" downpipe
is anyone running one of these and roughly what power are you running
i just ordered one of these for my bug sti and noticed it is a keyhole design , ie: it has 3" bore at turbo outlet but at wastegate outlet there is a tapered plate that funnels into the 3" bore. so is not a true open mouth.
im looking to upgrade my turbo poss md321t with supporting mods in the very near future and worried incase this will cause a restriction, or would it be ok
cheers

I've got the same downpipe and cat-back exhaust... Runing about 340bhp (soon to be around 360ish with uprated injectors) with SC38 turbo, FMIC and VEMS ECU on a 2,5L forged short block. IMO it a good quality exhaust. I woudn't worry about it being a restriction.
