Thats the kerissieg system. Those exhaust systems are ungodly expensive, around $10,000 for the setup. I think all of their systems connect to factory headers which makes the price seem even more unreasonable.
Kerissieg systems are total garbage. It is essentially a dump pipe before the muffler. They do make systems out of Ti and we all know just how well that holds up (note sarcasm) to heat cycling. Race car where every ounce counts YES otherwise NO. What's that saying a fool and his money will soon part.
