MagnaFlow Conv Direct Fit 13-15 Audi S6/S7/S8/A8 Quattro V8-4.0L

If you're working on your 2013-2018 Audi A8 Quattro, S6, S7, S8, or RS7 with the 4.0L V8 engine, this direct-fit catalytic converter from Magnaflow is built to get your exhaust system back to emissions compliance. It's designed to replace your original converter without needing any cutting or welding, making the installation much simpler. This part is crucial for ensuring your vehicle runs cleanly and passes emissions tests, keeping that check engine light off.

Magnaflow builds this converter using high-strength 16-gauge 409 stainless steel tubing, which is known for resisting corrosion and lasting a long time. The tubing is mandrel-bent to maintain the original exhaust flow dynamics, helping your engine perform efficiently and keep factory fuel economy. They also replicate the OE spun body design, using a single laser fusion weld that significantly reduces the chance of leaks. The compact, low-mass design helps with thermal efficiency, and the converter itself is designed to meet or exceed Federal emissions requirements for OBDII vehicles.

This converter comes with the necessary hardware, including bolts and a nut, so you won't have to struggle with rusted factory parts. It's a direct replacement for OE part number 4G0 254 202 NX, ensuring it fits right and functions as expected. While this converter is EPA-compliant for federal emissions systems, please note it is not CARB approved and cannot be shipped to California.
