Product Details

Magnaflow is well-known for its exhaust systems that offer improved flow and a distinct sound. For your 2000-2002 Audi S4, this direct-fit catalytic converter is designed to keep your emissions system working correctly and your check engine light off. It's built to meet California Air Resource Board (CARB) requirements, meaning it's legal for use in California and other states with strict emissions standards.

This converter is constructed with stainless steel, which helps resist corrosion, and features free-flowing, mandrel-bent tubing for efficient exhaust gas flow. Magnaflow uses advanced 3D scanning during their research and development to ensure this part fits and functions just like the original equipment. The spun body design replicates the OE style, and a single laser fusion weld is used to greatly reduce the chance of leaks. Its compact, low-mass design also contributes to better thermal efficiency.

Installation is intended to be straightforward with a bolt-on design, meaning no cutting or welding is typically required, and it includes gaskets to help ensure a proper seal. This specific converter is for the driver's side of your S4 and is designed to interchange with OE part number 8E0 253 057 JX.
