1967 to 1972 for sure, maybe later, B-body performance or "magnum" exhaust manifolds will fit, and look great, too. They are made for 2.5" pipes, as well. I have heard that the same years C-body "magnum" manifolds will fit, but I don't know that for sure. The passenger's side is essentially the same piece, but the pipe mounting flange is cocked the other way--which won't matter to a muffler shop. The driver's side C-body piece looks quite different, and you may run into interference issues with the way it kicks out at the pipe end, but I don't know.
