MagnaFlow Conv DF Audi S4

MagnaFlow is well-known for making exhaust components that perform well and last. This Direct-Fit Catalytic Converter, part number 49135, is designed to keep your check engine light off and ensure your vehicle meets Federal emissions standards. It's built for a range of Audi models, including the Q5, A6 Quattro, and S4, fitting right in place of the original equipment without needing any cutting or welding.

This converter uses free-flowing, mandrel-bent tubing to maintain factory performance and fuel efficiency, while the compact, low-mass design helps with thermal efficiency. The body is made from highly corrosion-resistant stainless steel, and the single laser fusion weld is designed to greatly reduce the chance of leaks, similar to the original equipment design. MagnaFlow uses 3D scanning during development to ensure a precise fit and function, so you can install it with confidence using the included gaskets and hardware. This helps avoid reusing old, corroded factory parts and ensures a solid seal.

This replacement converter is designed to meet or exceed Federal emissions requirements set forth by the EPA for OBDII Federally registered vehicles. It's important to note that this converter is not CARB approved and cannot be shipped to California. If you're replacing a damaged or clogged catalytic converter on your compatible Audi, this MagnaFlow unit offers a well-built, direct-fit solution.
