JIC Twin Spartan Cat-Back Exhaust System

So I was just browsing 3sx looking at all the great mods I can't afford and I noticed the JIC Twin Spartan Cat-Back Exhaust System. This thing is priced at $1200, and $1600 for titanium...now that's pretty damn expensive for a catback. I havn't really heard much about this particular one, and there is no way I would pay that much for it. But I was just curious if you guys knew any more info on it. Like performance-wise, weight, etc. The piping is 3" with a 4" resonator then splitting into twin 2.5" pipes into the polished stainless steel or titanium muffler cannisters which have huge 4.5" outlets. Just curious, as I haven't heard of anyone actually having this particular exhaust.
