Engine/Power - non turbo (All non turbo Imprezas) Who needs a turbo when you have 2500cc? Cams, intakes, exhausts, etc. The 2.2L and 1.8L Subies are cool too.

A full MRT header-back was dynoed for a 15hp gain on a stock car. Thats including the crappy muffler it comes with (skip the muffler, just get the rest, or just get the header/cat and have a custom midpipe/muffler put on it).

Another club member had a MRT header/cat/mipipe with a stromung muffler and a cobb intake and ran a 15.1 quarter mile... Thats not too shaby for not having much in the way of anything else done to the car. His car also dynoed for quite a bit of gains with that setup compaired to stock HP numbers... Cant do much better without internal mods imo.

Good question, I've been desperately trying to identify all the components of a N/A exhaust system for my wife's Outback.
I'm looking at:

Borla headers -->
Dynomax hi-flo cat -->
Custom-welded 2-1/4" piping -->
Dynomax Bullet resonator (midstream) -->
Straight-thru Bullet Performance 5x9x16" muffler -->
3" Borla resonated tip

That about right for a street setup? Am I missing some kind of pre-cat piping or something?
