Difference
The basic difference is in the name; a Spark Arrestor prohibits particulates of a over a certain size to escape the pipe, a Silencer reduces sound output via mechanical (chambers, baffle plates, Etc.) or sound deadening material (fiberglass, synthetic wool, Etc.) wrapped around a perforated core. Most modern Spark Arrestors also have a silencing component but, Silencers do not have Dept. Of Forestry approved spark arrestors.
Regardless of whether or not it is enforced, if we, as motorcyclists, do not make a concerted effort to ride quiet and respect the land we will continue to lose land! It seems as though people don't remember the good we do, i.e.; benefit rides, area clean ups, Etc. But they never forget an annoyingly loud bike, or unneccesary damage we do.
Okay, off the soap box now! :blah:
Enjoy your KDX, whatever you decide to do with the exhaust. Extensive dyno testing has shown that a Silencer/Spark Arrestor power loss is almost immeasurable when a motor is properly jetted for the conditions.

I have read (no actual experience) that an after market spark arrestor has little or no power advantage over the standard one. I think there may be a weight advantage though. If you search these forums someone has actually measured the weigh difference and posted the results here.
