MagnaFlow Conv Direct Fit 10-13 GMC Sierra 1500 V6 4.3L

MagnaFlow's direct-fit catalytic converter (part 5481578) covers a broad range of GM trucks and SUVs with the 4.3L V6, including the 2009-2013 Chevrolet Silverado 1500, 2009-2013 GMC Sierra 1500, 2009 Tahoe, 2009 Yukon, 2009 Suburban 1500, 2009 Avalanche, and 2009 Yukon XL 1500. It drops into the factory exhaust position as a direct bolt-on replacement.

The converter body is built from 16-gauge 409 stainless steel, and the mandrel-bent tubing follows the OE routing exactly to maintain smooth exhaust flow. MagnaFlow's spun body design with a single laser fusion weld mirrors the factory construction method, helping prevent leaks at the seams over the life of the part. Their development process uses 3D scanning to verify that every mounting point, bend angle, and dimension lines up with the original equipment.

This is a CARB-compliant converter, legal for sale and installation in all 50 states including California, Colorado, New York, and Maine. The kit includes a Torca AccuSeal clamp for distortion-free 360-degree clamping and a crush ring gasket for a tight seal at the connection point. All hardware is in the box, ready to go.

Whether you are addressing a check engine light, preparing for an emissions test, or replacing a worn-out converter on your GM truck or SUV, this MagnaFlow unit handles it with verified multi-vehicle fitment and full CARB certification. The 308 stainless MIG welds and precision-stamped collector design provide lasting reliability.
