You think I can drill a dyna?
06/01/06 at 19:55:22

Okay, so I've tried 4 different mufflers on my bike and I still can't get the sound I want.

The stock muffler sounds like a sewing machine.

I tried a supertrapp slip-on but it was too raspy

I tried a hollowed out sportster muffler (no baffle) and it sounded perfect, but way too loud.

I now have a stock dyna muffler, but only sounds marginally better than the sewing machine and it chokes off power unlike the hollowed sportster.

I really love the low rumble and thump of the hollowed sporty muffler, but I commute on it and the volume gets annoying. So, ideally I would love the sound and power of the hollowed sportster, but at about half the volume. Am I S.O.L.?

I was thinking of drilling a 3/4 inch hole through the baffle in the dyna (which actually mounts alot better than the sportster, too) to see if that would open up the volume and power. Any opinions?

Get a longer pipe and move the end of the pipe out past the wheel. Something like WD's fishtail.

Reply #2 - 06/01/06 at 21:18:17 we really like the sound of the 17" straight through dyna glass pack on debby's bike. it is only loud when you twist the throttle in an agressive manner. a little discression with the right wrist, can go a long way for good manners and acceptable DB levels.

it is not modified, it is probably custom chrome or drag specialties after market slip-on, i dug it out of the metal recycle bin, in back of the harley shop, it was probably scratched or something silly like that.

The longer pipe will put the sound further behind you. Still loud just not so much for you. Fishtail tip optional. Grin

Used a long drill bit. About twelve inches long. It would not drill through the baffle, so I used a hammmer and the drill bit and drove it through. A 5 or 6or 7 on the loudness scale. I get compliments on the sound from riders of various bikes.
Running a 155 main, 2 #4washers, and a free flowing air filter. Runs well, sounds swell.
