Graves Hexagonal Exhaust System for Yamaha MT-09

The Graves Exhaust System for the FZ-09, FJ-09 and XSR900 was developed using the same technology that has powered Monster Energy Graves Yamaha riders Josh Hayes and Josh Herrin to consecutive AMA Superbike championships.

The titanium headers feature an aggressive tapered design with cross-over pipes, these features allow for an increased throttle response and low to mid range power delivery while increasing the peak power output. Incorporated into the mid-pipe are two O2 sensor bungs, one for the OEM O2 sensor and the other allows for installation of a Dynojet Auto Tune O2 sensor. Graves advanced welding processes reduce oversized welds that can cause excessive heat buildup. A special pipe bending technique known as mandrel bending is used for all Graves exhausts to prevent wrinkles and ovalization of the exhaust pipes.

The diamond-shaped muffler matches the aesthetics of the Yamaha's lines and delivers the best possible power and torque. Graves Everlast packing produces an exhaust note like no other and holds up longer to the extreme conditions of a high-revving motorcycle. The muffler mounts directly to the motorcycle by way of a carbon fiber strap, this not only saves weight but gives the exhaust a stealthy appearance.
