For a sporty tuning of your KTM Duke, we offer you here with the Gianelli Intersport Black Line an easy to mount exhaust system, which is almost identical in construction to the Arrow models. Only the carbon end cap can be purchased from Arrow. The Black Line, which gets its name because of its black aluminium outer shell, provides a better sound for your KTM Duke. This can be further optimized by removing the catalytic converter, but then the exhaust becomes very loud and the EC type approval expires. According to the manufacturer, the exhaust system we deliver with muffler, mounting bracket, center pipe and mounting material allows for an increase in engine performance, especially in the medium speed range.
