This happens by design. HD decided that they should make their mufflers
with removeable baffels. This means it takes about 15-minutes to go from
legal to horribly loud levels. For each baffel removed, the db level
goes up. I'm not sure you can actually create a straight pipe (one
baffle may not come out; I'm not sure), but based on the sound levels I've
heard, I wouldn't be suprised.
