Bolt this BMP performance manifold for massive 12-14 horsepower gains on your Arctic Cat 1000 twin. This is simply the easiest power you can buy for your machine. Simply Bolt on and go, just use premium pump gas. 07-08 M1000’s require more fuel to be added with our adjustable pressure regulator or use a boondocker efi controller. But F1000’s, Xfire1000’s, and 2009-10 M1000’s can simply bolt on the manifold with no other fuel mods. This manifold works great with stock, ported and big bore motors as well with our performance single fatt azz pipe.
