<p>Sandwiching it between the exhaust and a can will hammer it - not
surprised it fell apart! It'll be getting the vibration
(relatively low frequency) as well as the noise frequencies you
were blocking - that energy had to go somewhere...</p>

I used a couple feet to patch a break and muffle the noise in an
exhaust pipe on my wife's DD. It was held in place with a can
and hose clamps. It worked fine for a couple weeks then started
to get loud again. Yesterday I pulled the can to see what was
going on and just about all the wrap was gone. </div>
