[QUOTE="Rich Rohrich, post: 80136, member: 16241"] The interactions between the silencer and the pipe tuning are vastly different between a two-stoke and a four-stroke. The influence of the silencer on wave tuning is far greater on a two-stroke, but it isn't accurate to say that a shorter silencer ALWAYS produces more bottom end on a two-stroke, and the specific length of the silencer on a four-stroke has little or no bearing on power or sound output. Generically speaking, four-stroke silencers with GREATER volume will TEND to have a lower DB rating, but that ignores a whole host of other factors, so even that statement is fairly stupid to make. You can count on that fact that a HUGE amount of engineering dollars went into the design of the silencer on the CR450, and random attempts to "improve" at home are only likely to increase the noise and decrease the horsepower. I realize that won't stop people from trying though. [/QUOTE]
