hello everyone! well, my 03 lancer ozrally exhaust is done, im going to be ordering a new header with a srs catback exhaust. but my question is, my stock exhaust manifold coems with a cat in it...so, if i get a new header, i wont have the pre cat anymore, will this set off a cel? if so, can a cel eliminator help? and will it also pass emissions? im thinking the obx header 4-2-1 because of the lifetime warrenty, cant beat that. im in canada, its epa regulations, not california. thanks a lot everyone!
