Great info thanks Gordie.

For a new exhaust check out Supersprint.  I've had mine for a few years.  I 
had my car chipped for about a month before installing the exhaust - 
definitely a difference.  Looks and sounds good, too.  Not loud.  Was about 
$650 cat back from BMP.  You don't hear about Supersprint much in Audi 
cirlces  - too bad - great product.
