MagnaFlow Conv DF 01-06 BMW M3 3.2L Rear Mani

If your 2001-2006 BMW M3 is showing a check engine light related to emissions, or if the original manifold catalytic converter is failing, replacing it with a direct-fit unit like this one from Magnaflow is a solid move. This converter is designed to bolt right into place, meaning no cutting or welding is needed, which simplifies the job considerably. It's built to meet Federal emissions requirements, so you can be confident it will help your M3 pass inspection and keep that warning light off.

Magnaflow uses a free-flowing, mandrel-bent tubing design to ensure exhaust gases can move efficiently, helping to maintain the factory performance and fuel economy your M3 is known for. The construction features highly corrosion-resistant stainless steel, with durable MIG welds holding the spun body together. This design replicates the original equipment's form and function, and the single laser fusion weld is intended to greatly reduce the chance of exhaust leaks. The compact, low-mass design also contributes to better thermal efficiency.

This converter comes with the necessary flange gaskets to ensure a proper seal during installation. It's designed to interchange with OE part numbers 11 62 7 832 064 and 11 62 7 834 674. Please note that this converter is EPA-compliant but not CARB approved, so it cannot be shipped to California.
