Hey David;
Were you turboed?  I have that option, but if I can avoid a muffler, for all of the reasons mentioned, including the Mistral crash, I would prefer it.  Noise-canceling headsets are cheaper than all of the other options.
Thanks;
Greg

Greg,
 
I flew my first 100 hrs like that.  It was acceptable, but still a little louder than I wanted so I bit the bullet and added the extra pipe and hung a muffler under the airframe.  Personal preference, but I am glad I did.  Much more pleasant now on long trips and I get compliments on how quite my RV sounds.
