Description

The MagnaFlow HM Grade Federal/EPA Compliant Universal Catalytic Converter 99779HM is designed to help keep the check engine light off by meeting or exceeding Federal emissions requirements set forth by the EPA. This universal design allows for installation in a wide array of vehicles, fitting by dimensions rather than specific year, make, or model. It features durable stainless steel construction for high corrosion resistance and a single laser fusion weld to reduce leak possibilities. Its compact, low-mass design promotes greater thermal efficiency. This part is compliant with legal standards for OBDII Federally registered vehicles with Federal/EPA Emission systems.
