M4’s carbon fiber slip-on for the FZ-09/MT-09 creates an awesome sound that will give you goose bumps. This slip-on requires cutting of the stock exhaust system (see detailed instructions below). It removes the stock catalytic converter and reduces the weight of the Yamaha by 10lbs. You will also see an increase in performance of 5 horsepower over stock.
