I'll probably need to get new cats, any recommendations for a 01 audi a4 2.8 quattro?

 

anyone?

 

You can have a shop cut out and weld in a new flex pipe. I just had this done this past Monday on my '99 2.8 and it took an hours worth of labor (or less). Depending on the shop, you're looking at anywhere from $80 to $200 total for one side.

If they weld a new piece up, you'll get a little whistle sound, sort of like a turbo (hah). I've also noticed a little more drone around 1600 RPMs when steady.

I can't offer recommendations on full pieces, but I'm sure someone will chime in. There's a thread on this that's a bit old: https://www.audiforums.com/forum/b5-...uh-nuh-169784/
