Well I'm running stock exhaust manifolds right now through straight pipes with the borla stingers at the rear. I have 3 months left until I have to get the vehicle emissioned. Its an 85. Now I want to get my hedman longtubes before then, thataway I can run a single high flow cat with the borlas at the rear. Now, if I get the headers w/o air injection set up, will the EMISSION place FAIL me ??? Cuz I think I remember them looking to see if I had the pump there, but dont recall if you need it connected to the headers. Do you guys know if i'll pass or not? Any feedback is appreciated. Thanks in advance.
