Mod....that doesn't mean every single pipe sold, especially these days, is too loud. Some of these things are pretty tame, and they give a sled different exhaust sound and in some cases moderate performance gains. I say to each his own with their exhaust or other mods. When Harleys start being held to the same standard as me on my Apex, I'll be 1st in line to say start handing out tickets. Until then, palease, spare me the drama and leave me alone out on trail 8 between Conover and Boulder. If the pipe meets DB standards, it's legal and nobody's doing anything wrong. This topic really gets me steamed. I can be sitting in my car with the windows closed and have some total clown go screamin by me on the road and scares the crap outta me on a nice peaceful drive home. Those pipes aren't legal either, but law enforcement looks the other way because Harley's are made in WI and we don't want to aggravate the bikers and manufacturer. But me ridin in the middle a nowhere, I have to worry about some D near russia agent writin me up for scarin a tree. Total double standard and makes no sense.
But by all means, lets be reasonable about the noise and buy only pipes within the DB limit. (wink, wink, nod, nod) Off soapbox.
