420cc engine exhaust sound test - we do have a 3rd exhaust to try on this engine but it wouldn’t fit this long tail kit so we will update the video again on the future This all stainless exhaust system will fit our 10hp, 13.5hp and 15hp engine. Also, Honda GX300 series engines, Predator 420cc engine, Duromax 16hp and a ton more! #mudskippermudmotors #mudskippermotors #mudmotor #mudboat #smallengine #gokart #gokarts #minibikes #minibikelife #minibiker #gokarting #gokartbuild #4stroke #smallengine
