Yeah... the alunimum can didn't work... damn it. It was almost completely blown out after about 50 miles. My hope was the it would be flexible enough, but it ended up tearing about 60% of the way around the circumference of the pipe.
I replaced it with a "sleeve" made from a spray can of Ortho Hornet/Wasp Killer. Not as quiet, but should last more than a day... I might still wrap the whole thing with fiberglass mat to take it down another notch but hoping this works...
