Now install the new one and loosly bolt it up, tighten up the exhaust. Once you have the exhaust tightened, tighten up the converter.

A catalytic converter is replaced pretty much the same as a muffler. Measure the replacement unit and cut the pipe section out. Then slip the new unit on and weld or clamp it in place.
