Silencers are one of the most popular upgrades for many sledders.
Simplicity of the add-on coupled with performance gains and weight savings are promising, but not all manufacturers deliver. Check out our other reviews of silencers. Thanks to Doug for some more good info. Also note that any exhaust modifications are illegal in Wisconsin, and the DNR folks are looking for and ticketing violators. With my '98 Arctic Cat Powder Special EFI version I decided to look for an aftermarket silencer to gain a little performance increase and to achieve some modest weight loss in the process.
