Construction & Materials

Built from stainless steel, durable, corrosion-resistant, handles repeated heat cycles and daily exposure. Includes a model-specific link pipe connecting the canister to the existing mid-section. Slip-on configuration, rear muffler replacement only, original header stays.

Sound & Performance

By modifying the internal chamber and exhaust flow path, the Rogue produces a more pronounced tone compared to stock. Sound intensity varies by model, fuel mapping, catalytic configuration, and DB killer setting. Comes with a removable DB killer for sound adjustment.

As a slip-on, this primarily affects acoustics and rear-end weight. Any perceived change in throttle response varies by overall bike configuration. Does not include ECU remapping or fuel controllers, arrange tuning separately if required.

Compliance with local noise regulations is the owner's responsibility.
