Audi RS4 Catalytic Converter Customer Reviews

This was a quality made product. It welded so nicely and gave clear directions as to how it was to be installed. The check engine light went off. Car sounds perfect.

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.
