Re: Beer Cans For A Quieter Muffler!
No- I think the can works well. Like I said, the moment it came off when I was riding, it was a much more noticible and surprising difference than when it was on. The aluminum can does'nt have enough tensile strength or weight to resonate much- it's just another baffle.
Any longer pipe or extension can only lower the tone and cut down on volume, not increase it, unless I suppose one's hearing is more sensitive in a lower range.
I'd be a little careful about stuffing anything here- you don't want to increase the back pressure.
