Made from lightweight titanium, the optional link-pipe is designed to be used with both the Slip-On Line (Carbon) and Slip-On Line (Titanium) exhausts. It delivers an increase in power and torque, and creates an improved linear curve across the entire rev range, coupled with weight savings. When installed on the Slip-On Line (Carbon), the sound becomes louder to boost to the senses, and when added to the Slip-On Line (Titanium) the unique sound is further increased, displaying the exhaust’s true racing spirit. When fitting the link pipe to the Slip-On Line exhaust, the bike’s ECU must be remapped. The optional noise insert should be used when the Slip-On Line (Titanium) and optional link-pipe are used in conjunction with each other.For perfect performance, throttle response, and durability, special mapping developed by Akrapovi?
