neither.
you will need to have an exhaust shop make a new exhaust for you. 3inch is recommended. -------------------- 15PSI - 30MPG - Megasquirt Tuned

its a different engine. the downpipe is in a different position than your st headers, and the factory st exhaust is too small for a turbo car.
if this is a huge problem, than your not going to like all the rest of the stuff you need to do to finish your swap. -------------------- 15PSI - 30MPG - Megasquirt Tuned

on a 3s, a 3" exhaust will make more power than a 2.5 or 2.75" exhaust, even with minor mods.
dyno proven over on mr2oc. most aftermarket mufflers you see with a 3" inlet will have at least a 3.75-4" tip. IIRC defgeph's tip is 4.75"..i double dog dare you to tell HIM it looks rediculous. lmao -------------------- Former Team 5SFTE pro member ;)
