Default Re: Beer Cans For A Quieter Muffler!

but beer cans add just as much noise via the flexure of thin walls - like an infernal kazoo - or like a dome-resonator dobro guitar

you need thicker walls than a tin-can, i'm afraid.

(I used a "Brasso" bottle which is a tinned mild steel can with a threaded bottle-top on one end. I removed the base of the can leaving the rim end on, drilled a few holes round the open 'bottle-end' end and used a hose clamp to clamp it to the end of normal exhaust. The result was slightly more rather than slightly less noise. Not what I expected.)
