Expansion Chamber Banana Pipe

This Expansion Chamber with Muffler will enhance your power output by expanding the volumetric efficiency 2-stroke bike engine. In addition to adding a boost in the top end speed, this muffler improves the use of any left over energy from the burnt exhaust exiting the cylinder. This helps aid the filling of the cylinder for the next cycle, and all is done with a muffler to stifle the sound of the exhaust.
