77 lemans olds 403 exhaust question
 

Okay I need help with trying to track down the exhaust adapters to make header back exhaust work on manifold back. Preferably two bolt. Cause that's the manifold I have. Any help would be awesome.

Take your car to the nearest exhaust shop and have them bend you a couple of down pipes. I have never seen "adapters" to connect up engine to front exhaust pipes.

I'm sorry what I meant by adapters is the set of down pipes that can then let you use a header back exhaust system. On manifolds! I don't have any exhaust shops near me. So internet is my only way.

I checked the PYPES website and there’s nothing available for your application.

You need to find the nearest exhaust shop even if it’s not nearby and have the down pipes made up there. Maybe you can source the two manifold flanges beforehand or perhaps the shop might have a variety of them.

It’s either this or you won’t be driving the car.

The car can be driven with the manifolds only with the rest of the exhaust hanging under the car. If you have AAA with a service upgrade you can get a free 100 mile tow a couple times a year which would be the best way to go.
