Description
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 for select KTM motorcycles. This listing includes both Rogue 1.0 and Rogue 2.0 styles under a single product page, with model-specific fitment options available via the variant dropdown.
This exhaust system replaces the stock rear canister assembly and includes a compatible link pipe matched to the selected motorcycle model. It is engineered to modify the visual profile and acoustic output of the motorcycle while retaining the original header system.

Construction & Materials
The Barrel Rogue Exhaust is manufactured using stainless steel, a material commonly used in motorcycle exhaust systems for its durability and corrosion resistance. Stainless steel withstands repeated heat cycles and exposure to road moisture, making it suitable for daily use.
The system includes a model-specific link pipe, designed to connect the exhaust canister to the existing mid-section of the motorcycle. Proper fitment depends on selecting the correct motorcycle variant.
This is a slip-on configuration, meaning it replaces only the rear muffler section. It does not replace or modify the factory header assembly.
Acoustic Characteristics
Slip-on exhaust systems are primarily installed to alter exhaust sound characteristics and rear-end aesthetics.
By modifying the internal chamber structure and exhaust flow path, the Rogue system produces a more pronounced exhaust tone compared to the factory muffler. Sound intensity and tone may vary depending on:
The Rogue exhaust is supplied with a removable DB killer, allowing adjustment within the system’s intended sound profile.
Compliance with local noise regulations remains the responsibility of the motorcycle owner.
Installation Overview
Installation involves:
-
Removing the factory exhaust canister
-
Connecting the supplied link pipe
-
Mounting the Rogue canister
-
Securing hardware to specified torque
-
Checking alignment and exhaust sealing
Professional installation is recommended to ensure proper fitment and prevent exhaust leaks.
No permanent engine modification is required when installed correctly.
Performance Considerations
As a slip-on system, the Barrel Rogue Exhaust primarily influences exhaust acoustics and rear-end weight distribution. Any perceived change in throttle response or engine behaviour may vary depending on overall motorcycle configuration.
This product does not include ECU remapping, fuel controllers, or tuning devices. Riders seeking additional tuning must arrange that separately.
Ownership & Maintenance
Periodic inspection of mounting bolts and clamps is recommended, especially after initial installation. Exhaust systems are exposed to heat cycles and vibration, and proper torque retention ensures long-term reliability.
Stainless steel surfaces can be cleaned using appropriate non-abrasive cleaning agents to maintain finish quality.
