Graves 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 flash tune map this system produces a solid 15+ HP in the midrange and 25+ on the top of the horsepower charts. This tune also removes any computer error codes the bike will have when installing performance exhausts.
Graves 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 repeat-ability is second to none. It comes with a single Lambda receiver bung for on track data logging or Dyno tuning. The spring tabs are made from 4MM thick Titanium wire for long life.
The silencer is has a Titanium entrance cap and attaches to the 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.
