Product Details

The 2004-2006 Audi A8 Quattro 4.2L uses a specific catalytic converter to manage emissions and keep your check engine light off. This direct-fit converter from Magnaflow is built to meet Federal EPA standards, ensuring your vehicle stays compliant. It's designed to replace OE parts like 4E0 254 550 TX and 4E0 254 551 X, making installation straightforward without needing to cut or weld your exhaust system.

Magnaflow uses advanced 3D scanning during development to ensure this converter precisely matches the original equipment's fit and function. The tubing is mandrel-bent for consistent flow, and the spun body design replicates the OE style. A single laser fusion weld is used to greatly reduce the chance of exhaust leaks, and its compact, low-mass construction helps with thermal efficiency. The converter is constructed from highly corrosion-resistant stainless steel, specifically 16-gauge 409 stainless steel for the tubing and 308 stainless steel for the MIG welds, which helps ensure a long service life.

This converter comes with essential gaskets and a Torca AccuSeal clamp to help you achieve a proper seal during installation. It's designed to meet or exceed Federal emissions requirements for OBDII Federally registered vehicles. Please note that this converter is not CARB approved and cannot be shipped to California.
