403 non stock exhaust headers ‘77 Lemans

[Flashflood]

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?https://uploads.tapatalk-cdn.com/20240511/a90e5b385c5f00a3cfa5d121e8e5fc15.jpghttps://uploads.tapatalk-cdn.com/20240511/8c99fdf851a2ed19ad84843550fc0272.jpg

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.
