Review on Enhanced Performance: 47cc 49cc 2 Stroke Pocket Bike Mini Quad Exhaust Pipe Muffler with Expansion Chamber by Jason Childs

Great exhaust system for small engines. I used it on my 52/49cc. I have the motor I used in the review photos. That exhaust system is almost perfect after cutting off the suspension and this bike is very, very small which is impressive. Judging by the custom motor mounts, I'm no welder or mechanic. So I could "customize" it, but it's almost complete, very, very minor exhaust leak. Build quality has been good so far, will update if anything changes.
