Magnaflow 08-10 BMW 528i 3.0L Direct Fit Converter

Magnaflow is known for making well-built exhaust components that improve flow and sound. For your 2008-2011 BMW 528i, their California Grade CARB Compliant Direct-Fit Catalytic Converter, part number 5571374, is designed to keep your emissions system working correctly and your check engine light off. This is a direct-fit unit, meaning it's made to bolt right up to your existing exhaust system without needing any cutting or welding, making installation much simpler.

This converter uses free-flowing, mandrel-bent tubing to ensure smooth exhaust gas flow, which helps maintain your vehicle's performance and fuel efficiency. The construction features highly corrosion-resistant stainless steel tubing, specifically 409 stainless steel for the main body and 308 stainless steel for the welds, giving it a long service life. Magnaflow uses advanced 3D scanning during their research and development to ensure this converter matches the original equipment's fit and function precisely. The design replicates the OE spun body style with a single laser fusion weld, which significantly reduces the chance of exhaust leaks. Its compact, low-mass design also contributes to better thermal efficiency.

This converter is specifically built to meet or exceed California Air Resource Board (CARB) requirements and has undergone extra testing for legal use in California and other states with strict emissions regulations. To make installation straightforward, it comes with essential gaskets and hardware, including a Torca clamp, so you don't have to reuse old, corroded factory parts. This unit is designed to interchange with OE part numbers like 18 30 7 541 847 and 18 30 7 541 849.
