Re: Headers or manifolds?
My CJ had fenderwell headers of unknown manufacture when I got it. I hated them for many reasons. A few months ago I got some used manifolds and built a single exhaust system using 2" pipes from the manifold, Y'd together into a cheap 2 1/2" in/out muffler buried way up next to the rear driveshaft. The new setup is less vulnerable, quieter, and much easier to work with. Surprisingly, it performs at least as well as with the headers. I have found no down side at all to losing those headers.
