hi ive just finshed fitting my new decat front down pipe to my 95 wrx import and what a diffrents it has made to the car you can hear the turbo whistle like made, the turbo spool up is well i can find words to describe it, this is a top mod for more power and an easy job if the turbo bolts undo ok ha if your thinking od fitting one of these get on the case stright away you will see what i mean, oh i forgot to say my95 is fully decated, i hope to here your views on decating scoobys

 

Decatting early imprezas is a good way to release 'hidden' hp.
I had mine done (93wrx) and was extremely happy with the extra va va voom.
Remapping ,though, will get you the full advantage from it imo.
