I bought my B6 S4 with just over 50K miles on it, and the only mod that was done by the original owner was the installation of a Milltek resonated exhaust. I didn't really like the huge exhaust tips, so I added some new tips. Now 3.5 years and 20K miles later, I kinda wish that I had the original exhaust. So, if anyone out there has a B6/B7 S4 Cab (I am pretty sure the Cab has a different exhaust from the sedan) and is interested in a Stock / Milltek exhaust swap, let me know! Nothing wrong with the Milltek, I just don't really care enough about the performance gain vs volume gain.
