Audi RS6 Catalytic Converter Customer Reviews

The unit was fairly easy to install. I had to add a 4" extension and when I located it where the O2 sensor was about in the same position as the original there wasn't clearance for the sensor. I had to rotate it to find a location where it would clear. Wound up having to be at an angle and as an engineer I like things square with the world. The converter worked and the car was able to pass inspection.
