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.

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.

Comments??? Mark S. Looks pretty interesting. I need a small, lightweight muffler for the single rotor project, and have been thinking of these: http://www.burnsstainless.com/UltraliteMuffler/ultralitemuffler.html It sounds like there's either ceramic, or stainless packing in the Burns muffler though, and no lifetime warranty.
