Dennis,
The outside of the muffler did change color a little.  Out of the box it looked almost like polished stainless steel.  Now it still looks shiny, but it has a definite honey color to it.  Yes, I plan to fly it again.  If the packing material melts, or gets pulverized, so be it.  As long as it hasn't lost its structural integrity I will fly it.  Of course, if it gets too loud for the ANR to handle the noise, or if people start to complain, then I'll change it out.  I'm growing weary of working on the exhaust system.  It is still quieter than the "auger" muffler.
 
Your system may be easier on the HP-2 due to 1) side port exhaust, 2) stock exhaust manifold, 3) tangential muffler and 4) more distance from the exhaust port to the muffler.  I may have to rethink my design to increase the distance between the exhaust port and muffler.  The instructions did warn that the muffler would get very hot due to some engineering double-speak.  Little did I know that it would spill its guts on the hangar floor. 
 
Yes, come on down.  Best BBQ for miles around.

 I have seen EGT numbers in the low 1800s while at full throttle and running slightly rich without any noticeable change in muffler performance.  So far no one has said my muffler is louder than my first flight. 

I never expected the HP - 2 to work or anything but the Renesis - but I did not expect to see "stuff" melting and dripping out either. 

Mark - are you going to fly it again as is or what is your plan - I may want to fly over to Lockhart and watch!  I am ready for more Barbecue also!

Mark,

Did the stuff get on the bottom of your plane?  Has this affected the sound of your exhaust?  Did Dennis' muffler do this?

I noticed his muffler had a white coating on the outside like it had been hot.  Has yours turned color?

I wonder how hot the muffler gets at high power settings?  Didn't you say something about a hand held temp gage?

OK, I can see this is going nowhere.  So I guess I'll have to tell you.   This is what came out of my new HP-2 muffler after a short 20 minute flight.  What you saw in the previous picture was the packing material MELTING and dripping out the end of the muffler.  In the second picture, you can see it oozing out of the little holes in the intermediate housing.  I was expecting it to "blow out" eventually, but I wasn't expecting it to melt and run out the tailpipe.  This just blows my mind.  Where to go from here???  Maybe I should replace the packing with titanium shavings, or lithium crystals.

Start the year off right. Easy ways to stay in shape in the new year.
