The only way I was able to fix this problem was to support the exhaust pipe. I bought a bracket at a local automotive store and mounted it on the firewall. More than 150 hours later and it still looks good. As soon as I figure out how to attach a photo I will do it.

<p>Add me to the list of broken mufflers now too. No visible cracks during my annual last September (2021) at 76 hours, but in my last flight (99 hours) the tailpipe departed the airplane during landing roll out - broke off the entire flange at the weld (gusset too). Please, no comments about my landing techniques. Today I'm installing a new muffler and tailpipe I purchased from Keith at Wicks.</p>

<p>After having my cracked muffler welded 3 times in the course of 440 hours I ordered a new one from Wicks. Got it in about 10 days as they were out of stock. It is the new and hopefully improved version. We shall see!</p>

<p>The vibration from engine to muffler has to be different being attached to the engine verses the motor mount. Hopefully ULPower did some statics/dynamics calculations to determine if this is better.</p>

<p>Tim, I had the older style which cracked after less than approx 50 hrs of engine time. Ordered and installed the new version as you describe. So far no issues and I thinnk there is much less bending stress on the bracket due to the increased length of the bracket and attach point on the engine.</p>

<p>David,</p>
<p>Which style of muffler support brackets do you have? The older ones that are shown in the Zentih UL-Power install guide show the brackets attaching to the motor mounts.</p>
<p>The brackets for my engine are much longer and attach to back of the engine case just below the upper motor mounts.</p>

<p>How far outside the cowl is your pipe? I planned on about 5 inches raked towards the rear slightly but have seen many with a heck of a long run. </p>
