After a search i see there are a few options for the exhaust header. Any down side to putting aftermarket ones on?
Do they have a shorter life span compared to stock?

no down side at all putting an aftermarket header, probably cheaper than a new OEM one. Id imagine they will last quite a long time. stainless will probably be more $$ but last longer. don't expect big HP and TQ gains. 5-10HP gain
