A lot of aftermarket manufacturers use "not legal for street use" as a generic disclaimer to cover their butts. Whether it's actually illegal depends only your local vehicle law, and whether you'd actually get stopped depends on how loud it is and the attitudes of local enforcement. In my area, one particular town that's known as a bike destination routinely singles out motorcycles for noise checks, but elsewhere it's generally not an issue (uhhh, so I'm told).Anyone got pulled over for an aftermarket exhaust? Since it's not legal to have them on the street, and it's only for the track.
Yeah I know what you mean, last time I was in LV, a guy on a scooter pulled up next to the truck and had a pathetic sounding fake rumble to it.Location must make a big difference. Here in Las Vegas it seems that most any vehicle can go down the road loud enough to set off car alarms and rattle the windows in your home without a problem. I rode a '89 Yamaha XT 600 with a Supertrapp exhaust and 20 diffuser disks for 30,000 miles here and never had a problem. (FZ6R still has stock exhaust - for now) On the other hand, my son in his '93 Honda hatch with a "fart cannon" has had repeated problems with law and has gone back to a stock looking exhaust. It was nowhere near as loud as any bike with a modified exhaust system. Seems like profiling to me!
