There are a few people with them. I don't think Tony ever really "launched" the 3" kit like the 2.5. It's only really appropriate for boosted applications, which limits the number of people that would pursue it in the first place.
FWIW Cosmogirl, based on my experienced with the other FI stuff, you can't go wrong. The quality is absolutely phenomenal.
Edit: nm, he did put up a launch page.
Fast Intentions 3" (Twin Turbo) exhaust is here!
