QD Twin Gunshot Silencers QJ Motor 921 RR 2025

Twin slip-on system with aggressive sound and Euro 5+ compliance

Developed specifically for the QJ Motor 921 RR, the QD Twin Gunshot Silencers deliver a bold racing aesthetic and a deep, assertive exhaust note while remaining fully compliant for road use. This 1-into-2 slip-on configuration transforms the rear of the bike, giving it a more purposeful stance and a sound to match its performance credentials.

The system features twin Gunshot silencers with lightweight titanium sleeves and magnesium end caps, paired with a dedicated pre-silencer designed to balance characterful sound output with regulated noise limits. All pipework is manufactured from high-grade AISI 304 stainless steel and fully TIG welded for strength, durability, and precise fitment. A carbon fibre heel guard, produced in QD’s in-house composites department, completes the package with a motorsport-inspired finish.

Supplied as a complete kit, the system includes all required mounting components and QD’s service card. Once registered, this allows activation of the manufacturer warranty and access to the homologation documentation.
