MagnaFlow Conv DF 01-03 Mercedes S500 Driver Side CA

This is the driver side, California-grade catalytic converter from Magnaflow, part number 454037. It's made to keep your check engine light off and ensure your 2001-2003 Mercedes-Benz S500 runs cleanly, especially in California and other states with strict emissions rules. You get the converter itself, plus a Torca clamp to help with installation. Since it's a direct-fit design, it's made to bolt right up to your existing exhaust system without needing any cutting or welding, making the job much simpler.

Magnaflow builds this converter with free-flowing, mandrel-bent tubing, which helps your exhaust gases move smoothly for optimal performance and fuel economy. The body and tubing are made from highly corrosion-resistant stainless steel, specifically 409 stainless steel for the tubing and 308 stainless steel for the welds, so it's built to last. They use advanced 3D scanning during development to make sure it matches the original equipment's fit and function precisely. The single laser fusion weld is designed to prevent leaks, and its compact, low-mass design helps it reach optimal operating temperature quickly for better thermal efficiency.

This converter is designed to meet or exceed California Air Resource Board (CARB) requirements. Magnaflow has tested it thoroughly to ensure it's legal for use in California and other CARB-restricted states on the specified Mercedes-Benz S500 models. It interchanges with several original equipment part numbers, including 220 490 06 20 80.
