Turbo that connects and sits at the muffler?

I had heard there was a turbo available or in development that supposedly connected and sat back by the muffle and was supposedly going to run around $2k. Anyone here of this? (Yes I know this sounds absurd)

www.ststurbo.com

And plan on spending a lot more than $2K

How does it stack up with other turbos?

The turbo system cost around 3.5k, but I have a group buy going on fbody.com I was trying to do one on this site but I don't think I would be allowed.

The system has been on my car for about 7 months now. I was one of the first testers, and have alot of info on STS. The kits are in the $3XXX.
