    MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 49573 helps keep the check engine light off. DIY installation is easy with the proper tools (no cutting or welding required). With features including mandrel-bent tubing to eliminate flow restrictions and stainless steel construction to resist corrosion, you can have confidence in the quality of this catalytic converter.

This direct-fit catalytic converter is designed to fit the 2001 Chevrolet Blazer and 2001 GMC Jimmy. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed Federal emissions requirements set forth by the EPA, complying with legal standards for OBDII Federally registered vehicles with California or Federal/EPA Emission systems.
