My neighbour just bought a 2007 Sportster 1200. It has, AFAIK, the stock exhaust system on it. I think it makes a pleasingly throaty sounds as it is.
Anyway, as as far as the straight-pipe morons and race-can rice boys go, I’ve got no freaking sympathy for them at all. Hope they get pulled over and ticketed repeatedly until they learn their lesson. Making all that noise is mostly about “Hey! Look at me! I’m a freaking moron”, anyway.
It’s too bad that this will end up limiting the ability of everyone to put moderately louder, lighter and/or performance enhancing exhausts on their bikes, though.
I’m also pretty sure that laws that require bikes to be quieter than according to DOT and FMVSS regulaations will be overturned.
Finally, we also need to do something about idiots with fart cans on their rice-boy cars, and also idiots in (mostly) pick-up trucks with ridiculously load Flo-masters and whatnot on them.
Btw, I put my money where my mouth is. When I bought my current bike I had the previous owner remove the very nice, but extremely loud slip-ons that he had put on it and replace the original mufflers. Maybe it does sound a lot like a v-twin ATV now, but I don’t ride to impress other people with the racket I’m making, anyway.
Also, being stealthy draws less attention from the cops when I’m breaking other traffic laws. :)
