Yamaha R9 Graves Titanium Works Exhaust

Graves Motorsports Yamaha R9 Full WORKS Titanium Exhaust System with carbon fiber silencer. Graves' precise engineering develops precision products that are designed to outlook, outperform and outlast the competition. Graves Exhaust systems are designed for the elite rider seeking top of the line performance, fit, finish and value. This exhaust system was developed using the same technology that has powered the Graves Racing Team to 31 Professional AMA National Championships including 9 Superbike Championship titles and 3 Side x Side Pro Titles (Pro Stock and Pro Mod UTV).

We did not allow compromise in the development of this system. Material diameters, lengths, the silencer core size and length are optimized for maximum power output throughout the throttle and RPM range. Combined with Graves’ exclusive FTECU flash tune map this system produces a solid 8+ HP in the midrange and 13+ on the top of the horsepower charts. This tune also removes any computer error codes the bike will have when installing performance exhausts.

We use the same 1.00 MM thick wall high heat grade Titanium tubing used on our performance Superbike exhausts. This material is designed special for maximum durability and oxidation resistance up to 800*Celsius / 1472*Fahrenheit. It is designed to live at almost twice the temperature of normal Grade2 Titanium. The tubes are precision bent and cut with the latest equipment available. The tubing is then welded in fixtures designed so that repeatability is second to none. It comes with a single Lambda receiver for on track data logging or Dyno tuning. The spring tabs are made from 4MM thick Titanium wire for long life.

The silencer has a Titanium entrance cap and attaches to the 265mm Carbon silencer body. The silencer is hung with a carbon fiber hanger strap for the cleanest look possible. The silencer body attaches to the end caps with stainless aircraft grade rivets and Titanium silencer bands. The inter core tube is made of stainless that slips over the entrance and into the exit cap that is made of Titanium and accented with a titanium beauty cover with a 60* slash cut.
