This California Grade converter installs in the factory close coupled location with no cutting or welding. The spun body copies the OE shape so one laser fusion weld takes the place of the usual seam, and free flowing mandrel bent stainless tubing keeps exhaust flow close to original. The 59 in assembly carries pre and post converter oxygen sensor ports plus a secondary air tube connection, runs a ceramic substrate, and includes Torca clamps and nuts. It is CARB certified under Executive Order D-193-179 and is also New York certified.
