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.

The exhaust pipes are made from 1mm thick high-grade titanium that is resist heat up to 1472 degrees Fahrenheit ensuring no discoloration.
