Graves Motorsports 2017-2024 Kawasaki ZX125 Full Exhaust System with Titanium silencer. 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).

This product is intended for closed course competition use only. Use of this product for any other purpose is strictly prohibited. 1. “NOT LEGAL FOR SALE OR USE IN CALIFORNIA” / 2. “NOT LEGAL FOR SALE OR USE IN CALIFORNIA ON ANY POLLUTION CONTROLLED MOTOR VEHICLES” / 3. “LEGAL IN CALIFORNIA ONLY FOR RACING VEHICLES WHICH MAY NEVER BE USED, OR REGISTERED OR LICENSED FOR USE, UPON A HIGHWAY”

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. 

We use high heat grade Titanium tubing. 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 Grade 2 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 mounts to the motocycle using a built in strapless aluminum mountain bracket for the cleanest look possible. 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 and accented with a Carbon Fiber beauty cover with a 60* slash cut. 

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