It happened to me yesterday in mid air. Got louder and by the time I landed it was still on but the can was cracked in several different directions. I would love to have a tuned pipe although my plane has plenty of power as it is. I still have my first original muffler that was crashed on take off to use while getting another muffler. Can any one tell me if a DA muffler is thicker/sturdier/worth the extra money compared side by side?
