Ive made progress. Got the bottom 2 nuts off the bolts on both sides from
below the car, through the wheel wells. The top left is next and the top
right seems to be the most difficult. Ill keep the list posted. I thought
that Bosal was the original exhaust supplier to Audi for North American
cars? They sent me the correct cat for the pax side but the other one has a
T.D. Plate welded to it. Looks like it is for a turbo diesel. Im calling
them today to find out what gives.
Thanks for your input so far!
