403 non stock exhaust headers ‘77 Lemans
I have 77 Lemans with a 403. I can't seem to find a good answer to a set of aftermarket exhaust. (Headers) that I can run on my car. I had a set of flowtechs no good they just hit the frame. So, without major modifications, I'm back to square one. Does anyone have any ideas. I also saw this set of hookers anyone know if these work? There's also these shorty headers from headman?

Although I don't have a '77 Lemans, I would think that the shorty headers would be your best bet just due to a reduced overall size which would have less conflicts with other pars of your car. Another idea , although a long shot is see if someone here has a '77 Can Am, some of which came with the 403 and if they have put headers on them successfully.

Headers designated for '77 Cutlass would probably work.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
