The Magnaflow Universal Catalytic Converter; OEM Grade; 2.50-Inch is designed to keep vehicle emissions within federal EPA standards, helping prevent the check engine light from triggering. This catalytic converter functions as a replacement part that fits a wide range of vehicles by effectively reducing harmful exhaust emissions. Its universal design allows it to adapt to multiple vehicle configurations while maintaining environmental compliance.

      Material Quality and Durability. Constructed with corrosion-resistant stainless steel, this catalytic converter features a spun stainless steel body with high-strength 16 gauge 409 stainless steel tubing and durable 308 MIG welds. The unit incorporates a ceramic substrate with an expertly formulated catalyst blend to maximize efficiency and emissions control.
