Expansion Chamber Exhaust, Muffler combo adds more power to your motorized bicycle. It is designed to run best on a 66/80cc engine, but it will still add a lot of power to your 48/49cc engine. Our Expansion Exhaust pipe will also give your bike a more “throaty” sound. In addition, they dramatically increase your low and mid-range power while still giving a bit of a boost at the top end. These are designed for stock to mildly modified motorized bicycle 2-stroke engines, and the header length, expansion chamber size has been developed over much testing. Please note: they will fit standard exhaust studs on 48/49cc; 66/80cc 2-stroke bicycle engines.
*please note* Finish quality can be a little rough. Please note that there may be scratches, overpainting and not-so-perfect chrome. However, none of these blemishes will affect performance, and they will most likely be covered when you add exhaust wrap.

We recommend that you wrap this exhaust with high quality exhaust wrap. The exhaust pipe will get very hot, and it can burn you – even with exhaust wrap in it. Take caution to avoid the pipe when bike is running and for at least 1/2 hour afterwards. Always wear long pants and appropriate safety gear when riding.
