MagnaFlow's California Grade direct-fit catalytic converter carries CARB Executive Order D-193-191 and is certified for use in California and New York, installing in the factory location with no cutting or welding. The 12 in spun body pairs a ceramic substrate with mandrel-bent 409 stainless steel tubing, and a single laser fusion weld reduces the chance of a leak. One oxygen sensor port is provided at the pre-converter location. A flange gasket, five bolts and seven nuts ship in the box.
