This Graves Motorsports Cat Eliminator exhaust is designed for the racer on a budget seeking the closest performance exhaust to our full race system. We did not allow compromises 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 11+ 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 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. The spring tabs are made from 4MM thick Titanium wire for long life.
The 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 is hung with a strapless Aluminum bracket and built 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 Titanium.
This system performs like our superbike pipe and shows like jewelry.

There is only system to get for any Yamaha. Got the Titanium Exhaust to flow better with the rear polished swing arm on the R1M, its not a perfect match but its two different types of metals. It looks amazing and sounds even better.
Also installed the Flash tune with the graves map. The bike is 10 times better, its not so chocked up. I thought I was in 6th gear when I was actually in 5th.
Thank you, Very nice work, fast and free shipping
