The Graves EVR uses the factory exhaust motor and cables and custom mapping to improve torque and drivability at low to mid-range rpm and small throttle openings to create a more liner power curve and improved ride. This is particularly effective on exhaust systems with shorter silencers that can rob your bike of small throttle responsiveness while reducing the sound to acceptable levels. We did not allow compromise in the development of this system. Material diameters and lengths are optimized for maximum power output throughout the throttle and RPM range.
We did not allow compromise in the development of this system. The 2017-2019 R6 WORKS 7 Full exhaust system with more aggressive head pipe taper and machined joints for a perfect fit. 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 12+ HP in the midrange and 15+ 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 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 has a titanium silencer body attached to the deep draw tapered Titanium entrance cap and a deep draw 60* slash cut titanium exit cap and is attached with stainless aircraft grade rivets and Titanium silencer bands.. The silencer is hung with a strapless machined Aluminum bracket / anodized black and built into the silencer. The inter core tube is made of stainless that slips over the entrance and into the exit cap.
Features:
- Diamond Shaped Silencer Design (Carbon Fiber or Titanium silencer body with Titanium End Caps), configured to balance the R6's body lines and produce the best balance of power.
- Strapless silencer design mounts without the use of strap bands around the can using a tap mounted bracket that's integrated into the can. This design not only streamlines looks of your bike and saves weight.
- Constructed from High Heat Aerospace Grade Titanium that resists breaking down up to 800* Celsius 1472* F
