Just wondering if there were two mufflers in series or if one was a resonator.  Here is a link to a whole series of these devices, including resonators, mufflers, and resonator/muffler in one package.  It would appear that the resonator has packing of some sort.

I thought the muffler was a total joke when I saw that it had an unobstructed path right through it.  There is no glass or other fiber packing in it.   It's 6" in diameter and about 20" long.   There are two of these in series on this installation but I still didn't think it would be effective.

I only had it up to 3000 rpm so far but I'm encouraged enough to try one myself.  I'll get this thing tied down and do a full power runup before ordering though.
