OK, folks, I'm still learning and I'm reading conflicting info (ain't the Web great?)

1. Looking at a 100, I see 2 cats right after the engine (about under firewall), going into what looks like a big ole muffler midship, culminating in some sort of smallish round device at the end of the pipe (next to spare). I guess the cats are to reduce emissions using a platinum catalyst. I take it the big one is a "muffler" meaning a device to reduce sound in some ways. That correct? What's the rear gizmo for?

2. Is the arrangement similar for the 80?

thx
Eric

Eric,
If you are really interested then do a Google search on Heimholtz Resonators. It's a physics principle that uses specific sized cavities to deaden sound.

It's definitely waiting to get smashed. See pics of mine that were posted a few months ago. The resonator barely survived but the tip of the pipe didn't.
