Well, I must admit that sounds better than the inserts I stuck in. Hey, it
might be the thing - but, I am just a bit skeptical of how the ceramic will
stand up. Perhaps well - if you are not using a turbo housing or if you are
using a turbocharger to break up the shock wave. I believe you are using a
turbo so it might work out well.

Ed,
Did you see that these come with a lifetime warranty?

MessageMark it reminds me a bit of some of the "inserts" you can put in your
header. I tried some in my turbo block headers and while they did lower the
noise and I was initially pleased, the shock wave of the exhaust reduced
the mild steel they were fabricated from to small pieces within a month. No
question the muffler insert would probably withstand the heat being
ceramic - but, I would wonder about the shock. This is the shock that
reduced some of my early SS fishtail tube attachments to fragments in a few
minutes of WOT - pieces missing, gone like something had bit them out. All
due to metal fatigue.

Rusty,
According to their website, it sure does, <snip> "Easily replaceable
aerospace ceramic muffling cartridge"
But hey, its "aerospace" grade ceramic.

Looks pretty interesting. I need a small, lightweight muffler for the
single rotor project, and have been thinking of these:

It sounds like there's either ceramic, or stainless packing in the Burns
muffler though, and no lifetime warranty.
