MagnaFlow Manifold CARB Catalytic Converter - Honda Pilot 3.5L 2017-2022

MagnaFlow's California Grade CARB-compliant direct-fit manifold catalytic converter 6511893 is a close-coupled primary converter with an integrated exhaust manifold that keeps the check-engine light off. The single laser-fusion weld replicates 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 resists corrosion for long service life. Installation requires no cutting or welding, and the included crush gasket, washer, eight nuts, four bolts, and flange gasket ensure a proper seal. This converter meets California Air Resources Board requirements for legal use in California and CARB-regulated states.
