Has anyone here tried to cut an inch or two off their aftermarket slip-on? In the street world this is common to gain bottom-end. I have also seen the motocross racers do this for the same result. Thoughts?

Im not sure how much power is gained down low, or if any is lost anywhere else, but they sure do get louder.

On 2 strokes th lenght size and shape determine the powerband. Not like in a 4 stroke. Some motors likme more backpressure, sometimes less. All depends

On a 2 stroke it is primarily the expansion chamber that affects the power band, as far as exhaust is concerned.
