RE: "ATV Silencer"
I've seen several ATV's fitted with the silencers. Yes, they do work quite well & I think you're going to be suprised - and pleased.
Some of the silencer applications even advertise that they INCREASE power. I would have to think that when they say this they are talking about torque, not horsepower.
If the horsepower remains the same asstock and it increases torque that would be agood.
