Magnaflow does not catalog a catback system for an '01-'02 I4 coupe and the dolt at Magnaflow couldn't tell me why it's not okay to use the one they have for the '98-'00 coupes. They only list a catback for the '01-'02 I4 sedans. Anyone know different, or if the '98-'00 can be used on the '01-'02 I4 coupes?
