Ernest,
Copy you on that! What material type and thickness was the Mistral muffler? Anyone know what their design was like? I know that something fatigued and plugged the flow, but I never saw a drawing of their muffler or had anyone explain how the failure actually occurred. It could have been a baffle plate that was not well supported on all sides. I don't see how that could happen to my muffler as the tube is welded to both end plates and the exhaust gasses don't strike the tube directly but swirl around it. Yes, a piece may fatigue over time and crack off, but I can't imagine how it could plug up the exhaust path. But I guess anything is possible if Murphy has his way. I'll keep a close eye on it though. With a little finessing, I'm pretty sure I can get my little inspection camera up the tailpipe. If that fails, I can remove one of the O2 sensors and stick the camera through the hole for a peek inside.

Ernest,
Yes, I can inspect it by looking up the tailpipe with a borescope. I can also look in through the three inlets. Initially I tried drilling holes but soon realized that this was futile. That's when I turned to the side grinder. Material is .065 inconel and is supported on both ends. If it starts coming apart I can cut the ends off and try something else. Mark
