ive searched and havnt found the answer im looking for....my question is what year headers/exhaust manifolds are interchangeable? does the HO ones from 91-95 fit 87-90 renix?

 

They will fit but do not have the bung for the EGR valve. If you plan on retaining your EGR especially if you state requires you keep it, you will have to get an exhaust shop to weld on a new bung or do it yourself. Not too bad of a job if you ask me. If you just want a straight swap for your renix you should look up pace setter. They make a renix style header with the bung already there.

 

i was looking at them but i wasnt sure how good they were i know alot of people say go with apn but i was hoping for somethin a little better than stock and im running 2 1/2 from the collector back
