MagnaFlow Conv DF 10-11 Cadillac CTS 3.0L

When your check engine light comes on and you suspect it's your catalytic converter, MagnaFlow's Direct-Fit Manifold Catalytic Converter 51548 is a solid option to get your vehicle running cleanly again. This unit comes with everything you need for installation, including two flat washers, one donut gasket, two bolts, one flange gasket, and two nuts. This means you won't have to hunt for separate hardware or reuse old, corroded parts, making the job much smoother. It's designed to fit a range of vehicles, including models like the 2010-2019 Cadillac CTS, 2010-2013 Mazda 3, and 2008 Toyota Highlander.

MagnaFlow builds this converter with free-flowing, mandrel-bent tubing to ensure exhaust gases move efficiently, helping to maintain factory performance and fuel economy. The construction uses highly corrosion-resistant stainless steel, specifically 16-gauge 409 stainless steel for the tubing and 308 stainless steel for the MIG welds, which means it's built to last. They use 3D scanning during their design process to make sure the fit and function are just like the original equipment. The single laser fusion weld is designed to minimize the chance of leaks, and its compact, low-mass design helps with thermal efficiency.

This converter meets Federal emissions requirements set by the EPA for OBDII Federally registered vehicles. While it's designed for easy DIY installation with the proper tools, remember that no cutting or welding is required, as it's a direct-fit replacement. It's important to note that this converter is not CARB approved and cannot be shipped to California.
