Hello SE-R People! This is my first post to the list and I have a quick question. I have a '97 200SX SE-R w/ Jim Wolf ECU & POP Charger, and would like to performance upgrade further. I'm thinking next step should be header or exhaust. I'm not sure which should be first. Any sugestions? I'd appreciate advice toward the right direction. Would this be in a FAQ somewhere? Sorry if it's a dumb question! Thanks, Brax
