Yup, I did it: I bought a full-up APR downpipe/exhaust system for the '00. Guess I've decided to keep the car, huh? ;)

So, this looks like a real PITA job. Who on the web (or otherwise) has the best step-by-step instructions? Has anyone on the list here done it already? Tips much appreciated.

BTW, I also bought their bipipe and diverter valves. I removed two good TT valves - they're only about a year or so old, two good plastic downpipes, and a throttle body y-boot (original with the car 125k miles ago) that looks undamaged (I wasn't having any probs, and I'm on my original turbos). If someone wants these make me a lowball offer (plus actual shipping costs) and they're yours.

I'm also looking for a VAG-COM. Can't believe I've gone this long without one... <shrug>
