oh and btw, i have found a bunch of stuff for our cars just by goin to google and typing "subaru legacy performance" or "legacy performance". not as much as i would like but enough to get me started. its hard for us 96-99s to find stuff without doing a motor swap, but i heard that 99 impreza rs motors are identical to ours, look into it.
i have the borla headers on mine. 2 high flow catco cats, and upgrade 2.5 inch pipe with a magnaflow muffler(also an intake). and let me say, minus the turbo spool sound, it definatly sounds like a very pissed off sti haha
