Magnaflow 2000 Audi A8 Quattro 4.2L Direct Fit Converter

Magnaflow is well-known for their performance exhaust systems, and they bring that same attention to detail to their direct-fit catalytic converters. If you're working on a 2000 Audi A8 Quattro with the 4.2L engine, this converter is designed to keep your emissions system functioning correctly and your check engine light off. It's built to meet or exceed California Air Resource Board (CARB) requirements, making it legal for use in California and other restricted states.

This converter is made with free-flowing, mandrel-bent tubing, which helps maintain smooth exhaust flow and supports factory performance and fuel efficiency. The construction uses high-strength 16-gauge 409 stainless steel for the tubing and 308 stainless steel for the MIG welds, offering solid corrosion resistance for a long service life. Magnaflow uses advanced 3D scanning during their research and development to ensure this part replicates the original equipment's fit and function precisely. The single laser fusion weld is designed to minimize the chance of leaks, and its compact, low-mass design also contributes to better thermal efficiency.

Installation is made straightforward because this is a direct-fit unit, meaning no cutting or welding is required when you have the proper tools. Essential gaskets and hardware are included in the box to help simplify the process. This converter interchanges with several OE part numbers, including 4D0 253 012 RX, 4D0 254 350 X, 4D0 254 550 AX, and 4D0 254 550 BX.
