This auction is for a new MPX performance lightweight repackable silencer for a 2013-2016 Arctic Cat 800 (F/XF/M/ZR). Unfortunately most of the aftermarket silencers available seem to be extremely loud and even if you do happen to find one that sounds good, after a season or two it sounds terrible because the packing inside is either all blown out or clogged up with oil or carbon. They really need to be repackable the same way all motocross and sport bike silencers are. This is the soloution to these problems. This silencer is repackable just like MX bikes are.

The goal here was to make something nice and lightweight, as quiet as possible when cruising around (its still loud at full throttle) and or course repackable. These silencers have a 5" diameter aluminum body and are a little longer then most aftermarket silencers to help make it a little quieter. As you see from the pics its built in two sections the same as motorcross silencers and is easily repackable. You just simply drill out the rivits in the bottom endcap and the endcap/core slides right out. Throw in some fresh fiberglass packing and rivit it all back togeather again and your silencer sounds like brand new again.

This silencer has a very a nice sound. Idle and cruise is nice and quiet (for an aftermarket silencer), its similar to stock. And still has a nice rip at WOT. No deep droaning sound that will leave you with a headache at the end of the day. And if you race or ride off trail and want your sled to be heard you can take this apart and pack it for whatever sound you like. Wrapping part of the core with header wrap before covering it with packing will certainly make it much more noticeable. You can tune it for whatever sound you like. This is the nicest silencer available for the procross right now. It weighs in at 5.1 lbs, The stock silencer was 21.3 lbs so thats a huge savings of over 16 lbs! Also a 2HP gain over stock based on testing from dynotech research.
