Graves Works 8 EVR Type-R Exhaust System Yamaha R6
The Graves Works 8 EVR Type-R Exhaust System is like nothing else in the motorcycle world. It features Grave’s EVR exhaust valve system that when paired with FlashTune software, provides an astounding 15+ horsepower at the top-end. But horsepower is only the tip of this iceberg, throttle response and usable power is where the EVR system shines. Unlike most aftermarket exhaust that features a straight pipe from front to rear, the EVR provides precise back pressure control and adjusts the exhaust valve base on RPM, speed and throttle input. The exhaust pipes are made from 1mm thick high-grade titanium that is resist heat up to 1472 degrees Fahrenheit ensuring no discoloration.
