...My bike is loud and i always wear ear plugs when i ride...
Now, THAT made me laugh!!! 'Kinda like saying that the 300 watt light bulbs are so bright in my living room that I gotta' wear dark sunglasses when I'm in there so my eyes don't hurt...
Even with stock pipes, your Harley will "rumble" more than most other makes. Probably have more low and mid range power, too. My '04 1200 had drag pipes when I bought it, got a pair of Nightster (slash cut design) mufflers here on the forum, lot of different models are interchangeable, but years aren't; they changed in '04, don't know if they've changed again since.
