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

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.
