I don't know it this is worth anything, but here is a test of the ceramic packing in the Aero Turbine resonator.

> Update to that last message,   the combination resonator / muffler does have some ceramic packing in the added section ahead of the muffler section  according to a different source.  The muffler portion is the same as the muffler only version.  Weight of the combination (XL version) is 10 lbs.  vs 6 for the muffler only.   I'm going for the combo anyway.

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.
