SSI manifolds are a simple bolt on item that makes horsepower. Our new Arctic Cat version it a torque monster! We made a recent dyno session at Dynotech Research to prove it. This manifold not only made great peak horsepower gains, it also had a crazy amount of mid range horsepower gains too. They are made of stainless steel and polished for the highest quality out there for your snowmobile.
