If your check engine light is on and you suspect a catalytic converter issue, this Magnaflow Direct-Fit Catalytic Converter is built to get your 2018-2020 Chevrolet Express 2500 back on the road. Designed to meet Federal emissions requirements set by the EPA, this converter ensures your vehicle complies with legal standards for OBDII Federally registered vehicles.

This converter is constructed from durable 16-gauge 409 stainless steel tubing, which offers excellent resistance to corrosion and helps ensure a long service life. The mandrel-bent tubing is designed to eliminate flow restrictions, maintaining factory performance and fuel efficiency. Magnaflow also uses durable 308 stainless steel MIG welds and a single laser fusion weld on the collector, which significantly reduces the chance of leaks. The compact, low-mass design also contributes to greater thermal efficiency.

To make installation as smooth as possible, this catalytic converter comes with essential gaskets and hardware, including a Torca clamp, so you don't have to reuse old, corroded factory parts. This part is designed to replace OE parts like 19420306, 84296974, and 85593477. Please note that this converter is not CARB approved and cannot be shipped to California.
