The MagnaFlow 557131 is a direct-fit catalytic converter for the 2016–2017 Chevrolet Cruze with the 1.4L engine. It is California Grade and CARB compliant, so it is legal in California and other CARB-restricted states, which many aftermarket converters are not. It bolts on with the included band clamp and flange gasket, no cutting or welding. Against universal-fit converters, it fits like the original part and is built from corrosion-resistant stainless steel; the trade-off is that it only fits one engine and model years, and CARB approval makes it a more specialized part than a generic universal unit.

The MagnaFlow 557131 is a California Grade, CARB-compliant direct-fit catalytic converter for the 2016-2017 Chevrolet Cruze with the 1.4L engine. It is designed to meet or exceed California Air Resources Board requirements. It has had additional testing for legal use in California and CARB-restricted states on the listed vehicles.
The converter is built from 409 stainless steel tubing (16 gauge) with 308 stainless steel MIG welds. A single laser fusion weld replicates the OE design. Mandrel-bent tubing keeps the original geometry and exhaust flow, and the compact, low-mass design allows greater thermal efficiency. The OE-sized barbed hangers are made of 410 stainless steel and are designed to reduce noise and vibration.
It installs with the proper tools and needs no cutting or welding. A band clamp and a flange gasket are included. MagnaFlow develops the fit using 3D scanning, so the part is designed to fit and function like the original equipment.
