Noise Ordinance in Denver Passed

[dm_gsxr]

cracking down on GDF-ing harleys and shitheads who like to drive above 10K rpms on rice rockets sounds like a great idea to me.

I don't see how they will ever enforce this though.

Sounds pretty easy actually.

*wooo* "pull over".

Officer visually examines the can and doesn't see a stamp.

"Here's your ticket for loud pipes".

Easier than pulling out a tape measure, counting off 25', putting the decible meter in position, going over to the rider and having him (or her) hit 3,000 RPM (or whatever the law asks for), "here's your ticket for loud pipes". Not to mention having to deal with certifications and calibrations and testing.

Sounds like a piece of cake really.

So I have yet to see where you are to get tested and approved, Anyone?

Do you mean the EPA stamp? I think it only comes on stock cans.

I don't think you can get your exhaust tested. Basically, you have to have the OEM muffler with the EPA stamp or you're up Shit's Creek (sans paddle). Additionally, I don't think it would've mattered even if you had sound data to back up your after-market muffler under the old law.

According to the Denver Municipal Code, Chapter 36, Noise Control, Sec. 36-8 Motor Vehicle Noise, (c):

"It shall be unlawful for any person or for the owner of a motor vehicle to modify or change the exhaust muffler, air intake muffler or any other sound reducing device in such a manner that the noise emitted from the motor vehicle exceeds the sound pressure levels as established in Table B of this section [which is 80 dBA at a distance of 25 feet - any RPM] or, is increased above the sound pressure level of the vehicle as originally manufactured. Muffler cut-outs, by-passes or other devices which increase sound pressure levels, or change the original manufactured exhaust system of any motor vehicle shall be considered a violation of this chapter."

So basically, even if you had some sort of documentation verifying that you met the 80 dBA limit at a distance of 25', the officer could hit you for having a modified exhaust. And now - all they have to look for is an EPA stamp. Without it, you're screwed.

As an acoustical engineer I plan to perform a variety of sound level measurements on my motorcycle in the coming days. Assuming I meet the old 80 dBA criteria as set forth in the Denver Municipal Code, I will prepare a document stating such and store it in my glove box. However, that will pretty much only be used with begging and pleading in the event I get pulled over - since it won't really matter without the EPA stamp. I guess it couldn't hurt to have on hand though.

The CS PD has been targeting bikes for the past couple of years under this same ordinance. I stopped riding the RF900 because it had a D & D can on it and I bought it that way from Colorado Powersports (in Castlerock) as I also didn't have the motorcycle endorsement on my license. I bought a stock Yamaha V-Max a couple weeks ago and it seams a little loud but it is bone stock.


I took a MSF course and as of a couple weeks ago received my M endorsement so I am legal now.

I think that it will be similar to here in CS. If you are not hammering the throttle or reving the engine or jackrabbit starts, you will not be producing obnoxious noise thus not drawing attention to yourself.

If you drive past a cop and are loud and or going fast and noisy, it will give them the a reason to pull you over to inspect. It is another way to control noise for those who are obnoxiously loud. IMHO. I don't like it but it is obvious that there is a problem with noisie vehicals and this will allow police to hit the worse offenders. I hope it actually affects the Harley riders, when they have straight through pipes, it is difficult for them at any throttle possition to control noise. I think sportbike with upgraded pipes are usually not straight through so don't produce as much noise or at least is controlable so they may not be at as great of risk. We will see I guess

simple solution to this problem...don't ride in Denver....or get your aftermarket pipe stamped !!

didn't they already try something like this but throw it out because cop cycles couldn't meet the ordinance, or am I thinking of something else?

OK, so this thread is 2 years old with 5000 views.

Has anyone actually gotten a ticket or know anyone who has? Or was it all just a lot of bullshit and hype?

Got stopped in Denver about 4 days ago. My new bike along with Temp Plates has a ridiclously loud ass M4 Full system.The officer just wanted to see if i was the registered owner. He made no comments on my exhaust.

Like it's been said beofre. If you're not being an ass-hat and rev'ing your motor at every red light or trying to get attention of some female, you'll be fine.
