Graves Aluminum Cat-Back Exhaust Suzuki DR-Z4S / DR-Z4SM

The Graves Aluminum Black Cat-Back Exhaust reduces weight and sharpens performance for dual-sport and supermoto use. Built to replace the heavy restricted factory muffler, it drops significant weight while delivering a deeper exhaust note and improved throttle response throughout the rpm range. High-heat aerospace-grade titanium tubing pairs with a black aluminum octagon silencer for race-developed durability and a clean understated look. A carbon fiber beauty cover finishes the stainless steel end cap, while an integrated mounting tab removes the need for bulky canister straps. It connects to the secondary titanium mid-pipe and slips onto the factory header, retaining compatibility with the original header heat shield with the included hardware.

• Octagon-shaped black aluminum silencer body with stainless steel end cap and carbon fiber beauty cover
• Extended titanium entry tubing and secondary mid-pipe for optimal exhaust flow and maximum heat resistance
