Hi, and thanks for looking at my post (he-he).

I recently bought a used header (here on an RX-7 club forum) for my stock '83 base model RX-7.
Was wondering if there is any documentation for the installation (step by step). The seller said it was pretty straight forward, just un-bolt and re-bolt....a direct swap. Although I am somewhat familiar with a wrench, it's always nice to have proper directions. We do have emission test here in S.E. WI so I want to keep as much stock equipment as possible. Any assistance would be most appreciated.

Thanks

 

the seller is right. is a real simple installation i believe is 4 bolts or nuts ?lol lol from the engine and 2 from the mid pipe, about keeping your smog stuff you might need to take it to a muffler shop do to the fact that the header is longer then your exhaust manifold

 

Its real simple to do. Just go out there and start unbolting it and you will be able to figure it out.
