This slip-on factory silencer has been developed in collaboration with Akrapovic for the very specific requirements of enduring offroad use (for enduro, motocross and supermoto too) and very carefully tuned to the KTM characteristics.
The benefits:

Improved torque curve combined with very rideable peak performance

More sensitive throttle response and resulting improved traction

Durability suitable for extreme enduro use

Made from titanium – that means: ultra-light

Fixed, welded bracket

Reinforced titanium end cap (factory team standard)

Pleasantly deep sound

Tuned for compliance with the latest applicable noise regulations
With removable noise reduction insert.

Can only be fitted in combination with original header.
