Our take on the Magnaflow 24183 Direct Fit Catalytic Converter 05-09 Scion tC 2.4 Rear

This is a direct-fit rear catalytic converter for the 2005-2010 Scion tC with the 2.4L engine. It bolts on in place of the factory unit using the included gaskets and hardware, with no cutting or welding. MagnaFlow builds it from stainless steel with mandrel-bent tubing and a spun body that mirrors the OE shape, and it is EPA federal-compliant rather than California-compliant. Compared with a universal weld-in converter, it saves fabrication time and fits like stock; compared with a dealer OE part, it is a lower-cost alternative that owners say fits and quiets the check engine light, though a few report fitment or durability issues.

About the Magnaflow 24183 Direct Fit Catalytic Converter 05-09 Scion tC 2.4 Rear

The Magnaflow 24183 is an HM Grade direct-fit catalytic converter for the rear position on the Scion tC. It is designed for the 2005-2010 model years and interchanges with OE part 17420-28520. It is Federal/EPA compliant for OBDII federally registered vehicles and is a 49-state, non-California converter.

The spun body is made of stainless steel, with 16 gauge 409 stainless steel tubing and 308 stainless steel MIG welds. A single laser fusion weld replicates the OE spun body design. Mandrel-bent tubing keeps the original design and geometry, and the compact, low-mass body is designed for thermal efficiency. Magnaflow used 3D scanning during development to match the fit and function of the original part.

It bolts on and uses the factory hangers, so no cutting or welding is required. Gaskets, hardware and Torca Accuseal clamps are included. The clamps apply an equally distributed 360-degree clamping force, and the new gaskets mean the corroded factory parts do not need to be reused.
