Does anyone have IMCO exhaust? It sounds awesome!

I hadn't heard of it until today. I listened to a sound clip and it sounds awesome. It has a really nice muscle-car sound to it. Does anyone have the "extreme" kit (pn - 55506)? The mufflers seem pretty friggin small so I wonder how loud it is...its hard to tell from the video.

Heres the clip...

Heres a pic of it and some dyno stuff (they claim 26hp and 32ft/lbs!! hahahaha get real!)
