Is it normal for a slip-on to become quieter with time? My brother has been complaining that the Two Brothers can he has on his R1 is considerable quieter after 1000 miles. I was under the impression that cans become louder as the packing material deteriorates.

Probably just getting USED to the sound......and it just 'seems' more quiet.

He should check his hearing :lol. I don't think it's getting quieter.. I had to repack my slipon because it got too loud after 12000 miles...
