once i get a few more lil bugs figure out around here, im gonna get a kamikaze header with 2.5 downpipe to a 2.5 inch hi flo cat with a full 2.5" custom catback, and probably a Sebring Performance Muffler.
My friend put the same muffler on his turbo saab and it helped him out a bit in performance when he upped his boost, and it stayed quiet when just driving, and will growl when u punch it, which is what I want.
