The 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 revving 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!
