Fits select 1999-2018 Audi, BMW, Buick, Ford, Jeep, Mazda, Mercury, and Volkswagen vehicles. This universal component requires cutting and welding for proper installation.
The MagnaFlow 51775 OEM Grade Federal/EPA Compliant Universal Catalytic Converter is designed for professional installers seeking a compact, high-efficiency solution for emissions control. Its unique 5-inch spun body features a single laser fusion weld, which significantly reduces the risk of leaks while enhancing thermal efficiency in tight spaces.

As an OEM-grade replacement, the 51775 features an expertly formulated catalyst blend to maximize emissions conversion and help resolve check engine lights on OBDII Federally registered vehicles. The low-mass design ensures fast light-off times and maintains factory-level flow dynamics.
