A4 questions

[DaveSenu@aol.com]

What is best exhaust for 99.5 A4Q 2.8 30V?  Stebro? what exactly is a cat 
back exhaust?

I think Stock Exhaust looks like

--C--\___Mufler--mufler--
--C--/

Is this right? 

Is their a true dual exhaust?  How much additional low RPM torque can be had 
from a Stebro or ? 

VAG programming for 99.5 a4, other then windows/roof up down from remote and 
rolling locks, anything else good that can be added?

trip computer, seems like at least one of the functions that should be on 
trip computer is instant speed and /or RPM in the center of the display?  
Anybody done this?  Anyone hack they existing code to make it better?

Any good aftermarket items that plug into VAG/diagnostic port?

I looked through archives but didn't find these items.
