CR-T Exhaust in carbon fiber or titanium, by SC-Project

The CR-T was originally designed in MotoGP and has long been the standard for performence, due to its ability to produce power, and made glorious motor music! This half system includes a decat link pipe in titanium, and uses the front half of the stock headers. Because the OEM cat is the choking point of the exhaust flow, there is no need to replace the stock headers on your Yamaha R1. They are actually very well made and have many hours of R&D behind them. The power increase comes when you remove the stock cat, and let the engine breathe. With this decat link pipe (titanium) you essentially eliminate the need for a full system. Pair this exhaust up with a Sprint Filter and a Rapid Bike auto tuner, and you are ready to race!
