My 2006 3.2 quattro needs a new Cat Convter. I took it to the local muffler shop and he claims none of his suppliers carry the part. I haven't had a chance to look underneath yet but he said it goes from the ex manifold down and when I look up the part at AOA it shows that it attaches with a flange to the downpipe. Does anyone know for sure what I need and where could I get one at a good price.
