Where do you buy your exhaust?

For the 73, I bought a 2¼" driver's side tail pipe from Year One. I bought a "turbo" muffler from a local shop who also bent the exhaust pipe and did the installation.

Some muffler shops will try to cheat by using your existing exhaust pipe end and flare up to make a 2¼" system. Problem is that the 1 7/8 inlet on the exhaust pipe will not match up well with a 2¼" manifold outlet. It gets hot enough to burn up the gasket and then you have a leak. If you have the front part of the Super Six exhaust, it will side step this problem.

Good luck.
