Has anyone on the site tried making their own glass pack style muffler/exhaust system for their mini bike? I've been kicking the idea around for a while, but haven't started on anything. I'm picturing a pretty basic style muffler/exhaust when finished all one welded piece. A tube (header/exhaust pipe/tail pipe) pre-bent with holes drilled in the "muffler" section, then a muffler body made from a larger diameter tube and welded with a cap around the perforated portion, then packed with fiberglass packing, and welded up to finish with another cap. I know a lot of work, when there are so many inexpensive header pipes and mufflers available online. But sometimes my mind wanders or your shooting for a certain look for the exhaust. I'm also just curious what one would sound like.
