need some help guys, i'm ordering a set of headers for my 97 camaro ss and on the ordering menu they asked if my engine had air-injection and egr or without air-injection and egr. can anyone tell me where to check or do i need to go to a bodyshop or does it really matter? the headers are pacesetters.
tks

 

your car has EGR and AIR injection, if you want to keep it emissions legal, the headers need them

 

Thanks man...really appreciate it.
