why put an aftermarket silencer on a kdx? In the justkdx engine hop-up forum, installing an aftermarket silencer is one of the last recommended mods. Very small power increase and a little less weight. The stocker doesn't have any packing to plug up and have to replace. Just remove the drain plug and tap it. Why mess with the packing issue? Granted the aftermarket ones have a bling-bling factor :laugh: . Can anyone give good reasons from experience why to change to aftermarket and why its worth the trouble to replace the packing?
