What is the internal construction of stock muffler

Has anyone dissected a stock WR muffler?

I'm curious how they are designed and how the exhaust flow works. Baffles, and that sort of thing. I have heard that the stock exhaust is mainly a mechanical muffler and that the FMF Q4 is also partially mechanically muted, therefore not relying on packing as much as many.

Ideally I would like a muffler quieter than stock, but much lighter. I'm wondering if a person could maybe fabricate some alloy baffles or something.

You have the cat, and 2 sets of baffles, plus the sparky which has a hideously small garden hose sized outlet. Not sure if it was Shredak but someone ripped one apart on TT and had an exploded view of it.

If you google "ronnies cycles" they offer microfiche views for just about everything.

For some reason the exhaust slide was not loading for me this morning.
Hope that helps.

Yeah it won't show you what's inside the can besides the sparky.

oh....sorry....I could not get it to load so I was not sure what details it would show.
