Graves Full Titanium Works 8 Evr Type-R Full Exhaust R6 2017-2024 Exy-18r6-Fvtt8

ALL NEW GRAVES TEAM DESIGN + EVR TypeR Valve Configuration. Developed from WINNING Championships - Graves Motorsports Yamaha R6 Full Titanium WORKS 8 Exhaust System with Titanium Silencer. Graves Exhaust systems are designed for the elite rider seeking top of the line performance, fit, finish and value. This R6 exhaust system was developed using the same technology that has powered the Graves Racing Team to 23 Professional AMA National Championships including 8 Superbike Championship titles! Requires FTEcu software purchased separately to use the EVR map . 

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
• Stainless exhaust port spigots
• Billet Hard Anodized 7075T651 Aluminum Flanges
• Single Lambda sensors come standard. FTEcu active tune sensor adaptability. 18 x1.5
• Advanced welding process showcases laser perfection welds
• Tapered header down pipes (Cores are altered in size and taper length for each motorcycle.
• Optimized Graves Spec flash tune maps on the FTEcu database for tuning (product shown below in up-selling links).
• EVR butterfly valve

What Chuck Graves the president of Graves Motorsports had to say about the release of Graves’s newest line of exhaust systems, EVR and the technology behind it:

• "The EVR or Exhaust Valve Type R is and electronically controlled valve that improves drivability at small throttle and low RPM ranges where it matters most to the rider. The systems can also be utilized to reduce sound by a significant amount without reducing maximum power output."
• What makes the Graves EVR different than the stock exhaust valves that racers commonly remove when the stock system is replaced with an aftermarket race system?
• That's pretty simple, we install it in a race system and tune the electronics to maximize efficiency. The current trend of sport bike enthusiasts has been attracted to short silencers simply for looks. Power output and drivability has been sacrificed exclusively for the trendy look. Secondly the sound levels of many of these systems has reached the level of irresponsible and annoying for even the youngest riders. The aftermarket has responded with sound inserts to bring these short power robbing systems to an acceptable level. The real drawback to this is that once the sound inserts are installed the rider can now feel the negative effect of the system and the overall performance. In most cases, I'd say 99.9% of all motorcycles that I have tested, the power output and throttle response is now far worse than the stock exhaust.
• With the EVR by Graves we solve all 3 issues, the power output, throttle response and the sound.
• Who else uses this system on their race pipes?
• Only Factory teams are using it now and most of them are well hidden!
• Why hasn't this been done by the aftermarket before?
• Again, that’s pretty simple. Cost! To drive the valve requires hardware and software. At a minimum, you need an ECU that is capable and a motor. The emergence of ECU flashing has given us the ability to do this at a reduced cost because we can now control the stock ECU motor controls. We have designed our EVR systems to accept the stock motor and cables. This makes for a clean setup.
• So, is the FTECU flashing system is required to optimize the EVR exhaust system?
• That is correct. Anytime you replace the stock exhaust system with an aftermarket racing system it requires changing the fueling. In addition to air fuel requirements, the modern motorcycle engine control systems cannot be optimized by piggyback systems. Now the flashing of the ECU is common place. Graves has partnered with FTECU to manage these strategies to enhance our exhausts systems performance just as a Factory team would do.
• What if I already have a flashed ECU?
• What Graves has been telling our customers is that they should purchase the FTECU flashing kit when they purchase an exhaust from Graves. Graves provides maps for the user to install in their motorcycles ECU. We tell them that by having the FTECU flashing system in their tool box they can update their ECU whenever Graves publishes a new map. If they have the system already then, an updated map is all that they will need.
