I chopped the back end of the CVT exhaust off to make room for a 4" blower. Everything is nice and cool now but have a question. The CVT exhaust had kind of a downspout on the end, probably to keep mud and junk out. Mine just goes straight out. Does anyone know of a non flammable material to wrap around the end and zip tie on? I still need the air flow but I don't like the idea of a cotton sock. I could do an elbow but like the idea of slapping something on the end how it is.
