CST 6 is the fast road version of our exhaust for the RB cylinder.
Developed by Martin Cook to produce the good horsepower and torque
across a wide RPM range, this exhaust works between 6000 and 9000
RPM. This exhaust is made to suit those riders who want a higher
machine, that needs to be ridden hard but still with best torque for
this style of exhaust on the market. Not only that but they are handmade here in Britain! Looking for a fast road exhaust, that produces
a wide torque and power band then this is the exhaust for you!
Suitable for RB Cylinders
