Has anybody ever been pulled over because their bike was so loud and the cop tried to canary you with your stock pipe?

I come off lucky because on the opposite side to my compliance plate is a test verification for my exhaust noise levels.

I notice bikes don't get pulled up for this kind of stuff as much as cars..

Anybody experienced this? even if you have an aftermarket exhaust.. was anything said about your exhaust levels when pulled over..

im guessing it was a cop in a car, not a bike.

i can understand where hes coming from, if you were at 20000rpm lol but there should be some engraving on the stock pipe, and you can match that up to the noise verification plate thing on the front left side of the frame.

Yeh. I only ever get to 9k rpm in the suburbs as well but I suppose and still was loud enough.

Considering I just bought the bike I still had a valid roadworthy on my and the sticker was probably what helped most.

Cop's don't generally canary you for a loud pipe unless its ridiculously loud. But if they have a word to you about your bike being noisy, expect a EPA notice in the mail. Has happened twice to me in the past, just put on the stock pipe. You will have to take your bike to a exhaust shop generally to get a decibel reading cost is like $38. Swap exhaust back, they achieve nothing, waste a bit of your time and money. Life goes on.

I have always wondered how this worked. My cbr250 was rated at 94db at 7500 and my R1 reads 93-94db @5750

As anyone with a cbr250 would know there is a huge difference in power and noise at 7 grand onwards. I never really worried about it too much because i figured most cops wouldnt know the exact rules and as long as i have the noise plates on the pipe at least it looks legit.

I think most of the testers wonder how it works too.

According to the official EPA document, your CBR was supposed to be tested at 7250RPM and your R1 at 5000RPM.

The testing RPM seems to be determined from the RPM at which the bike makes max power (a percentage of, or a sliding scale).

I know trackside testing is just "You shall not make more than x dB". NFI how it's done on the road.. seems needlessly painful though.

I remember a little while back on the monster I was in a breatho when a cop came running up and said; "I love your bike, how much did it cost?" I thought I was fucked when I saw him running though :)

This is one of the reason why i never got around to selling my stock pipes. Its the only thing that really grabs the attention of a cop that could lead to a yellow sticker. Im sure quite a few of the mods could be yellow sticker worthy until they were passed by an engineer.[hr]

So what are the limits? i remember hearing 98db before.

Sounds like your's wasn't the loudest ever :p A few of the oldies will testify to my Megacycle as being the loudest in the universe.

I got an EPA notice sent to me in the mail .. can't remember if it was a disgruntled person in our street, or someone in a car that made the complaint :(
