Well, my 3.2 arrives in march. To kill time I've been reading lots here and on other sites. VWvortex has some pretty interesting .:R32 stuff which also pertains to our 3.2 A3s.
So, here are quite a few links on the exhaust flapper mod. The last links go to an incredibly well written instructional on wiring an elec swithc to control the flapper. Of course, it is for a .:R32, but the same should apply for the A3 3.2. Anyone here willing to try this?
In any case, I thought people here might find interest in this; enjoy!
Quote from VWvortex:
Q. What is the "flapper mod"?
A. It's basically just modifying the normal function of the exhaust flapper valve so that it either stays open all the time, or can be switched open or closed. It makes the exhaust louder at low speeds/low rpms, and gives a bump in hp and torque.

Important note: If you disable it in one of these ways, do *not* leave the rubber vacuum tube open. There's a vacuum pump back there that will run continously until it burns out, if you do. Be sure it's either clamped or plugged.

Can now wire up a 2 or 3 way switch inside the car to allow you to enable/disable the flapper on the fly. Extensive instructions here:
