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.

A little off of the subject, but close. Just got my engine and turbo mounted on the Lancair, and was wondering if anyone had ever exited the 3" downpipe right out of the side of the cowling, ala turbine exhaust types, (thrust???) it would eliminate 2 bends, and about 3' of pipe, and with the turbo, it should be relatively quiet. Any thoughts?
