Magnaflow Conv Uni CA 2.50in./2.50in. Straight/Angle Direct Fit Converter

If you're dealing with a check engine light on your 2008-2010 BMW 535i, a failing catalytic converter could be the culprit. This Magnaflow California Grade CARB Compliant Universal Catalytic Converter is designed to help you get back on the road legally, especially if you're in California or another state with strict emissions requirements. It's built to meet or exceed California Air Resource Board (CARB) standards, meaning it's undergone extra testing to ensure it complies with those tough guidelines.

This converter features a spun body construction made from stainless steel, which is great for resisting corrosion and ensuring it lasts. The single laser fusion weld helps prevent leaks, and its compact, low-mass design is actually more efficient thermally. While it's a universal fit, meaning it can work on a variety of vehicles, keep in mind that cutting and welding are required for installation. The stainless steel tubing is 16 gauge 409, offering good corrosion resistance, and the MIG welds are made from durable 308 stainless steel.

This is a solid option if you need to replace your catalytic converter and want something that meets stringent emissions regulations. Just remember to factor in the need for welding during installation.
