OEM Grade direct-fit catalytic converter for the 2001-2002 Chevrolet Cavalier and 2001-2002 Pontiac Sunfire with the 2.2L engine. It bolts in at the factory flanges with no cutting or welding, replicating the OE spun-body design with 16-gauge 409 stainless steel mandrel-bent tubing and a single laser-fusion weld to resist leaks and corrosion. The 1.75" flange inlet and 2" flange outlet match the factory exhaust, and a Torca clamp, flange gasket, and flat ring gasket are included for installation. This is the Federal/EPA-compliant version; it is not CARB-certified and is not legal for sale or installation in California, Colorado, or New York.
