FMF - SST Pipe
The SST is our top of the line 2-stroke exhaust pipe. Unique and trademarked via the SST module on the back and its chrome plating, the SST Exhaust system greatly improves the ENTIRE powerband. It was voted Product of the Year by Dirt Rider Magazine. The secret to SST is the patented shape of the exhaust system, and it's ability to increase horsepower through the use of sonic wave technology. The most noticeable element of an SST pipe are various bulges and funnel shapes, such as where the rear chamber meets the stinger section. There are also differences in pipe diameters and silencer junctions. The SST exhaust system changes the sonic waves, backpressures and exhaust gas temperatures that effect engine performance and throttle response. You get more power. And better throttle response. The SST System was developed by the team of Donnie Emler of FMF and Dave Simon, a pioneer inventor in sonic-wave technology.
