They maybe just what we need for our turbo installations to make them even more quiet?

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.
