Magnaflow 12-17 Chevrolet Express 3500 6.0L Direct Fit Converter

MagnaFlow CARB Direct-Fit Catalytic Converter for 2012-2017 Express and Savana Vans

When a fleet van needs a new catalytic converter, downtime costs money. This MagnaFlow unit (part 5582113) fits the 2012-2017 Chevrolet Express 2500 and 3500, plus the 2012-2017 GMC Savana 2500 and 3500 with the 6.0L V8, and it bolts directly into place without any cutting or welding.

CARB compliance across all 50 states means fleet managers and owner-operators do not have to stock different converters for different state requirements. Whether your vans run routes in California or cross-country, this single part number has you covered from an emissions legality standpoint.

MagnaFlow builds this converter with 16-gauge 409 stainless steel tubing shaped through mandrel bending, keeping the interior of each bend smooth and round. The body uses a spun design sealed with a single laser fusion weld, and all joint welds are 308 stainless steel MIG. OE-sized barbed exhaust hangers are made from 410 stainless steel to resist corrosion while reducing noise and vibration.

Two Torca AccuSeal clamps are included, each applying even force around the full pipe circumference to prevent distortion. Additional hardware comes in the box so there is no need to reuse corroded factory parts. MagnaFlow used 3D scanning to match the factory dimensions, which means the flanges and connection points line up for a straightforward replacement.

Six model years of coverage (2012 through 2017) makes this a versatile part for shops and fleet operations that service multiple vintages of Express and Savana vans.
