In my 25+ years riding 2 strokes, Pro Circuit 304 silencers are better than an aftermarket pipe. The longer 304 allows the power to rev out longer which is better for outdoor, faster motocross use. As long as your bike is jetted correctly for the stock pipe, there are no changes needed for the 304. True, effective, and simple bolt on power.Read All Reviews

The 304R gives the bike a lower RPM boost of power that fits tighter, slower racing. If you try to rev this silencer out , the power will sign off sooner than the longer 304 version. This is just as good as an aftermarket pipe itself. No additional jetting changes required. Pick the correct 304 for your needs and enjoy!Read All Reviews

tried a gnarly pipe and a fatty. gnarly is a good pipe for low speed rugged terrain, problem is when you get in open terrain with more high speed it takes a while to open up. fatty i prefer. It's a good all around pipe, it's like stock pipe but thicker steel. I ride both terrains, tight and open range. It pulls great at low rpm and opens up fast in open terrain... If you ride all around terrain, want torque at low rpm and quick responce on higher rpm, you want the fatty.Read All Reviews
