MagnaFlow 93180 is the HM Grade replacement for the rear catalytic converter, a clam-shell body direct-fit unit in 16 gauge 409 stainless steel with a ceramic substrate, an attached aluminized steel heat shield and flange connections at both ends. It measures 16.5 inches overall and carries no oxygen sensor ports, so the factory sensors stay upstream in their original locations. This is the Federal EPA 49-state part rather than a CARB certified one, which suits vehicles registered outside California and the other CARB states. Two flange gaskets are included and installation needs no cutting or welding.
