Magnaflow 10-14 BMW 535i GT 3.0L Direct Fit Converter

When you need to replace your catalytic converter, especially if you're in California or another state with strict emissions requirements, Magnaflow's California Grade CARB Compliant Direct-Fit Catalytic Converter is a solid option. This unit is designed to keep your check engine light off and ensure your vehicle meets emissions standards. It's built with free-flowing mandrel-bent tubing and highly corrosion-resistant stainless steel construction, meaning it's made to last. You can install this converter yourself using the proper tools, as it's designed as a direct fit with no cutting or welding needed.

Magnaflow uses advanced 3D scanning during their research and development process to ensure this converter fits and functions just like the original equipment. They've replicated the OE spun body design, and the single laser fusion weld greatly reduces the chance of leaks. The compact, low-mass design also helps with thermal efficiency. This converter is designed to meet or exceed California Air Resource Board requirements and has undergone extra testing for legal use in California and other CARB-restricted states. It fits a range of vehicles, including the 2011-2014 BMW 535i GT and 2012-2015 BMW 640i.

This converter interchanges with OE parts 18 40 7 645 241 and 18 30 7 594 923. Essential gaskets and hardware are included in the box to simplify installation. The tubing is made from high-strength 16 gauge 409 stainless steel for excellent corrosion resistance and a long service life, and the 308 stainless steel MIG welds are durable.
