I put a “V” shape rubber lips all around the buggy. it make a smooth oval shape, close the gap between the shell and the chassis, hide the “U” shape factory made for the exhaust. I flip the tune pipe ¼ turn to make the exhaust exit under the buggy. And I hold the exhaust with a peace of rubber tubing like a ring. I made shielded fuel line and a fuel cap “one finger lifter” extension (ideal for cold whether). I also put a ribbed black rubber hose on the pull knob, it put the knob easy to access when the shell in over.

See Yaa,
