you are, zzp lies and sells crappy tunes on top of the lies. but your new and dont know any better yet. i mean why would you question a leading parts seller like zzp?
they are not the only game in town, most of what they sell can be found cheaper else where, or used. headers dont have to cost 800 bucks either, but zzp thinks they should.
for headers most of us run speed daddy headers, 220 shipped most of the time. add some band clamps and your all set. for 250 in all.
