Barrel Rogue Slip-On Exhaust for KTM Duke 250/390, RC 390 & Adventure 390 – Stainless Steel (Rogue 1.0 & 2.0)

The Barrel Rogue Exhaust for KTM Duke 250, Duke 390, RC 390 and Adventure 390 is a stainless steel slip-on exhaust system designed as a direct rear-section replacement. This listing covers both Rogue 1.0 and Rogue 2.0 styles with model-specific fitment options via the variant dropdown.

This exhaust replaces the stock rear canister and includes a compatible link pipe matched to your selected model. It modifies the visual profile and acoustic output while retaining the original header system.

Rogue 1.0 vs Rogue 2.0

Rogue 1.0

• Stainless steel, black finish

Rogue 2.0

• Revised canister geometry with altered internal acoustic tuning
• Fuller, deeper exhaust tone
• Stainless steel, black finish

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.
