#242-708 Replacement Performance Baffle Inserts, Pair

This insert does the best at recovering torque curves without a loss in high end HP.  It does tend to quiet the exhaust down a bit but for the most part, these will be used in higher performance applications such as 124 and 128 big bore bikes that would be ultra loud to begin with.  An interesting tip on these:  If the customer wants more sound, you can raise the lip of the ramp about 3/16″ and the sound level goes up drastically without sacrificing much torque. Please see the attached dyno sheet for this insert.  The dashed line is before the insert is installed.  The solid line is with the insert installed.  You can see how drastic the change is.  We see this with most builds in which this insert is utilized.
