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 23 Professional AMA National Championships including 8 Superbike Championship titles and 3 Side x Side Pro Titles (Pro Stock and Pro Mod UTV).

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 use the same 1.00 MM think wall high heat grade Titanium tubing used on our Superbikes. 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 or the addition of FTECU’s Active Tune. The spring tabs are made from 4MM thick Titanium wire for long life.

The 200mm silencer is one piece with the tail pipe welded to the deep draw tapered Titanium entrance cap and attaches to the collector with a 60.5 MM machined Titanium joint for a perfect fit every time. The Collector attaches to the stock mount under the frame with a Titanium tab that has an 8MM machine Titanium nut welded to the tab. The silencer attaches to the motorcycle with a strapless aluminum bracket that is black powder coated and integrated into the silencer. The silencer sleeve is made of Titanium that attaches to the titanium 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 a stamped from Titanium and welded to deep draw Titanium tube exit cap beauty cover.

This system performs like our superbike pipe and shows like jewelry.
