    Worked great on GX100 Honda motor
  

*by R***M on Reviewed in the United States on August 6, 2023*

I put this on a Honda GX 100 motor which was on a bicycle , it did divert the exhaust and prevented burning the bar on the bike.For the price you cannot beat it compared to buying a muffler. Recommended for motorized bikes with Honda GX 100 motor.
