hello guys. i just got a 00 a6 2.8 quattro. i picked it up for a good price and needed something i could pile some miles on so i don't run up the miles on my other cars. I want to make a few cosmetic changes and need some help finding the answers.

1. Does the lower grill from the 02-04's fit on the 98-01's? I like the chrome accent on the newer ones and they look very close in size.

2. What is the exhaust outlet size? I want to add some tips and expose them through the valance like on the 02-04's. I just want to make sure i get the right size inlet on the tips... I think i saw a write up on here somewhere.

3. what are the rim bolt pattern and offset specs? I was thinking of adding some A8 or RS6 look a like wheels. didn't know if they would be a direct fit.

thanks for any help!
