Customer Reviews (4.8 / 5 · 5 reviews)

Hannah C. ★★★★★

Bolted right up to my 2006 A8 without any modifications needed, and the mandrel-bent tubing gave it a noticeably smoother exhaust tone. The check engine light has stayed off after a week of driving, which was my main worry.

Ruby C. ★★★★★

Installed this on my 2007 A8 and the fit was spot-on — no extra modifications needed. The mandrel-bent tubing feels solid, and it's nice not worrying about corrosion like with the old one.

Hazel H. ★★★★★

I was worried about the check engine light coming back after replacing my old converter, but this direct-fit unit bolted right up and has been perfect for the past 500 miles. The included gaskets saved me a trip to the parts store.
