Description

This direct-fit catalytic converter is designed to keep the check engine light off. It features free-flowing mandrel-bent tubing and highly corrosion-resistant stainless steel construction. It can be installed without cutting or welding, utilizing 3D scanning technology for a precise fit. The OE spun body design and single laser fusion weld reduce the possibility of leaks, and its compact, low-mass design allows for greater thermal efficiency. Gaskets are included for a proper seal. This part meets or exceeds California Air Resource Board (CARB) requirements and is certified for legal use in CA and other CARB-restricted states. MagnaFlow manufactures its products in the USA from its Oceanside, California facility.
