Magnaflow 09-14 Chevrolet Express 1500 4.3L Direct Fit Converter

Commercial vans rack up miles fast, and a failing catalytic converter can take your Express or Savana out of service. MagnaFlow 5481134 is a CARB-compliant direct-fit catalytic converter for the 2009-2014 Chevrolet Express 1500 and 2009-2014 GMC Savana 1500 with the 4.3L engine.

Bolt-On Replacement for Working Vans

MagnaFlow uses 3D scanning to match the factory exhaust geometry, so this converter drops right in without cutting or welding. That matters when you need the van back on the road quickly. Mandrel-bent tubing keeps exhaust flow smooth and consistent through every bend, replicating the OEM routing your 4.3L was tuned for.

Everything You Need in the Box

One of the biggest headaches with exhaust work on high-mileage commercial vehicles is dealing with corroded factory hardware. MagnaFlow includes two Torca AccuSeal clamps, a flange gasket, a crush ring gasket, a donut gasket, and two bolts, so you get fresh sealing surfaces at every connection point.

Built for the Long Haul

The converter body is 16-gauge 409 stainless steel tubing with 308 stainless steel MIG welds. The spun body design and single laser fusion weld keep things sealed tight, and the precision stamped collector maintains proper exhaust flow for fuel economy.

CARB Compliant Nationwide

Legal for sale and installation in all 50 states, including California, Colorado, New York, and Maine. Always verify your vehicle's Executive Order and Engine Family Number against the converter's CARB Executive Order before installing.
