I checked in again with Schaumberg Audi while I was there to pick up my
fuse-blowing wagon (they still can't make it reproduce), this is a
single 3" line with a racing muffler and a large short catalyst. They
claim that the new exhaust system by itself is good for 20 HP, a bit
more when use in combo with the modified ECU and RS2 manifold. Cost is
about $1500, so it's the most expensive of the options they offer.
I'll probably just do the modified ECU for now.
BTW, they also said that the 128 MPH speed limiter on the S6 can be
un-done with the detachment of a single wire. I suppose I'll
eventually find out which wire that is, and if so I'll post the info.
Anybody already know which one?
