The MagnaFlow 49501 is a semi-direct-fit replacement catalytic converter for vehicles that use OE part 17420-0D150. It is built from 16-gauge 409 stainless steel with mandrel-bent tubing and 308 stainless MIG welds, and it bolts on with the proper tools, no welding. It is Federal/EPA compliant, not California CARB legal, so check your emissions status before buying. Against generic weld-in converters it offers OE-like fit and flow; against CARB-approved units it is the cheaper route only for Federal-registered vehicles.

This is a MagnaFlow OEM Grade catalytic converter, part number 49501, with a semi-direct fit for specific vehicles. It is designed to meet or exceed Federal emissions requirements set by the EPA. It complies with legal standards for OBDII Federally registered vehicles with California or Federal/EPA emission systems. It interchanges with OE part 17420-0D150.
The tubing is 16 gauge 409 stainless steel, bent with a mandrel to keep an OEM-like design and geometry for smooth exhaust flow. A single laser fusion weld replicates the OE design and reduces the chance of a leak. The compact, low-mass design allows for greater thermal efficiency. The MIG welds are 308 stainless steel. The OE-sized barbed exhaust hangers are 410 stainless steel and are designed to reduce noise and vibration.
Installation requires no welding and can be done with the proper tools. Gaskets and essential hardware are included. Before installing, confirm your vehicle's year, make, model, engine size, emissions standard and location. Professional installation is recommended for proper sealing, sensor transfer and emissions-system performance. CARB-restricted states require a valid CARB-compliant part number and EO where applicable.
