View Full Version : What bolt size Cat to DP

12-13-2007, 09:30 PM
Yesterday, I noticed that my exhaust note seemed to increase in the cabin at lower RPMs. After driving around and listening to the noise, I thought that a.) I got more power from somewhere
b.) I've got an exhaust leak

After a little investigation, I determined that one of the three bolts, which attaches the Down Pipe to the Catalytic converter is missing. WTF? Anyways, I was wondering, if anyone knew the size of this bolt of the top of their head?

FYI the Bentley Manual didn't have the bolt size (at least that I'm aware of).

C'mon Audi guru's lets see who knows their stuff.[az]
