Good observation! I just built my muffler shroud last month and kind of guessed the flutes were intended to keep the hose clamps from sliding off. From what I can see, I like this new design better. The older design just seemed a little rinky-dink with hose clamps.... Thanks for sharing!

Good find, I’ve just finished building my 12IS. 121056 , so pretty close in serial numbers lol
