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

Drop weight and turn up the performance on your dual-sport or supermoto with the Graves Aluminum Black Cat-Back Exhaust. Designed to replace the heavy, choked-up factory muffler, this cat-back system sheds significant weight while unleashing a deeper, throaty exhaust note and improving throttle response across the entire rpm range.

Constructed with high-heat aerospace-grade titanium tubing and a black aluminum octagon silencer, this exhaust combines race-bred durability with a sleek, stealthy aesthetic. A carbon fiber beauty cover tops off the stainless end cap, while an integrated mounting tab eliminates the need for bulky canister straps. The system connects directly to the secondary titanium mid-pipe and slips seamlessly onto the factory header, retaining compatibility with the original header heat shield using the included hardware.

Features:

• 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
• Clean strapless canister design with integrated mounting tab
• Sheds nearly half the weight of the factory silencer (6.5 lbs vs 12.5 lbs)
• Includes USFS-approved spark arrestor / quiet core insert
• Includes hardware to remount the factory header guard for added protection
• Designed for closed-course competition use only
