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.

Absolutely love it!!

The sound is awesome, but not too loud and obnoxious. The engine runs a lot smoother and has increased torque low end and a better top end!! 10 out of 10 would recomend. We did have to cut and reweld the pipe to clear the down tube though. Not a big deal if you have a welder. I bet we could have just bent it and it would have cleared.
