Graves Motorsports 2023 + Kawasaki ZX-4RR Full WORKS Titanium Exhaust System with carbon fiber silencer. LOW Mount. 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 Teams to 31 Professional AMA National Championships including 9 Superbike Championship titles and 3 Side x Side Pro Titles (Pro Stock and Pro Mod UTV).

We did not allow compromise in the development of this system. Material diameters, lengths, and the silencer are optimized for maximum power output throughout the throttle and RPM range. Combined with Graves’ exclusive mapping, this WORKS system produces solid gains of 9 + HP through the mid-range and 23 + on the top end (sold separately or through a tuning shop of your choice).
We use the same 1.00 MM thick wall high heat grade Titanium tubing used on our Superbike exhausts systems. This material is designed especially for maximum durability and oxidation resistance up to 800*Celsius / 1472*Fahrenheit. It is designed to live at 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 repeatability 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 entrance cap and attaches to the Carbon silencer body. 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 with a 60* slash cut.
