Set, Pipe, Full Race System, WSS300, (Race) KTM 390 Duke
This full exhaust system has been conceived to meet WSS300 specifications and carefully designed to squeeze the most power out of the 390 Duke. The stainless steel headers are tapered and the sections hand- rolled and welded to give this system incredible looks as well as performance.
And with full spring mounting, fitting and removal of the exhaust is quick and simple. Ideal in a race environment.
By taking advantage of better routing under the engine, the exhaust can be made to optimize dimensions to exploit the motor’s full potential. In addition, by tucking it up through the swing arm, the exhaust does not have any clearance issues in tight bends and is kept away from side which is the most vulnerable position in the case of an accident, increasing its survivability.
The system features a primary silencer, which helps reduce the sound level without any loss of performance.
The system is also provided with a dB killer as well as a carbon heat shield.

For reference video clip below is the RC390 version and the sound on the 390 Duke is similair
Due to the new routing of the exhaust, it is necessary to re-route the water hoses and remove the thermostat, and we provide all the necessary hoses for this conversion. Also, due the exhaust running under the engine, the stock belly pan is not compatible and we provide some alternatives which are not included in the cost of the exhaust.
