I got this from a trade. It does not have the regular cylinder chamber. Who made this and does it functions like a tuned pipe?

A flow thru muffler. Generally and after market product from a couple of different manufactors. I have 3 or 4 of them, but I don't remember who made them. I used one on an old K&B 40 and another on a McCoy 60 I converted to RC. As Hobbsy says popular in the 70s. They added noise not power. They weren't tuned at least not very well. We used them in hopes that they would reduce the power "lose" of engines not designed to run with mufflers. Many of these engines were free ported and didn't respond well to tuned pipes anyway.

Hey guys...That sure looks like a Mac's muffler from the mid 70's...Nice and light, they were one of the best available back then. I got a whole shoe box full of mufflers from my early days, Semco was annother manuf. but that's not a Semco. I'll bet it's a Mac's.

Hi!
Looks like a Mac's muffler from the seventies...no good! Just loud!
No tuning effect compared with todays minipipes or full lenght pipes.

It is a Mac's muffler. You can buy a "plug" to fill the opening in the front. The muffler will still be load, but much better with the plug, available from Macs in
Sacramento (see their web page).
