Product Information
MagnaFlow's California Grade CARB-compliant direct-fit catalytic converter 5571981 replaces the rear underbody converter and keeps the check-engine light off. The spun-body design and single laser-fusion weld replicate OE geometry to reduce leak points, while free-flowing mandrel-bent tubing and a compact low-mass body support thermal efficiency and smooth exhaust flow. High-strength 16-gauge 409 stainless steel tubing and 410 stainless barbed hangers resist corrosion for long service life. Installation requires no cutting or welding, and the included gaskets and hardware ensure a proper seal. This converter meets California Air Resources Board requirements under Executive Order D-193-137 for legal use in California and CARB-regulated states.
