Great bolt on performance gains for your snowmobile. Available for many of the popular Arctic Cat and Ski Models with gains up to 12 horsepower. All manifolds fit simply replace the stock one for the horsepower gains. No jetting for efi controllers required, we just recommend using premium pump fuel. (except 2007 M1000 Arctic Cats in which we recommend the use of the BMP adjustable pressure regulator 241-0170 set at 47-48psi).
