Review on FLYPIG Silver Muffler Exhaust Pipe for 66CC 80CC 2-Stroke Motorized Bicycle Engine by Steven Jackson

I was not happy with the design of typical exhaust systems for motorized bike kits. I wanted it to be elevated and out of the way, but still aesthetically pleasing. This exhaust did exactly what I was looking for. I am satisfied with the appearance and quality. However, I warn you that the installation can be a little tedious and time-consuming. I had to heat the tube with a butane torch and bend it so it wouldn't get in the way of my pedals. I also used a grinder to reshape the flange a bit and even shaved some material off the crank arm. An alternative solution to my clearance problem was to fit a longer crank and cranks, but that would have been a job in itself.
