Well this is the second time this has happened to me so this time I wanted to get a bit more information about this BS and Bogus law from the cop.

This officer told me that the exhaust must be left unchanged how it came from the factory. OK - a few things, what happens when your exhaust rots out? Do you just leave it because it is OEM? What about motorsport divisions of car manufacturers -

AMG
Nismo
now Stasis - They all provide exhausts for cars that you can purchase from the dealer in MA.

I then asked him about Harley's and he said they are measured on a decible level and its different from cars. Cars have no decible level measurement only a visual inspection to see if its been changed.

Overall, I got off with a warning because I told him I bought it like this. He told me Audi's are easy to spot because they are whisper quiet from the factory. I guess he hasnt heard an RS4.

And my truck is louder than most audi's and I haven't gotten a ticket in that either.

Sounds hypocritical to me..

<b>Chapter 90: Section 16. Offensive or illegal operation of motor vehicles</b> states (in part):

No person shall operate a motor vehicle, nor shall any owner of such vehicle permit it to be operated upon any way, except fire department and fire patrol apparatus, unless such motor vehicle is equipped with a muffler to prevent excessive or unnecessary noise, which muffler is in good working order and in constant operation, and complies with such minimum standards for construction and performance as the registrar may prescribe. No person shall use a muffler cut-out or by-pass. No person shall operate a motor vehicle on any way which motor vehicle is equipped (1) with a muffler from which the baffle plates, screens or other original internal parts have been removed and not replaced; or (2) with an exhaust system which has been modified in a manner which will amplify or increase the noise emitted by the exhaust.

There is no decibal limit, but the officer just has to deem that it has been "modified" to amplify or inrease the noise. I got pulled over once, and they asked if I had a factory exhaust, to which I replied "yes, it is OEM from Audi, and you can inspect it for the manufacturer part numbers if you wish." I was told it sounded very "mean" and was sent on my way.

Some municipalities are strict on sound, and those rules vary town by town and are VERY subjective.

And since Ferrari's/Vipers/Lambo's come with a mean exhaust note they are ok but penalize Audi because they came quiet? Mass is the most politically incorrect state in the union. Some of her rules borderline on ridiculous and stupidity. If any vehicle is quieter than a Ferrari/Harley then it should pass.

can't be changed/replaced to be louder than stock. If your car's significantly louder than stock, it's just a risk you have to accept. I've been pulled over for my exhaust, no ticket tho.

pulled over. a milltek exhaust is REALLY quiet... the boston police just wanted to hassle me.

i did get a $50 ticket for it ...

and the state collects its bs-money?

you guys are buddies right? I haven't talked with him in a while, last time i checked the s4 was gone, n he said he hadn't gotten his vdub yet, if hes still planning on it...

It's not illegal to modify the exhaust, it's only illegal to modify the exhaust to make it louder than what it was when it came from the factory.

But inorder to prove this (if you get a ticket and you plead not guilty) the officer will have to somehow show that your exhaust is louder than stock exhaust. The easiest way is to get you to admit it. So they'll ask you a few questions to try and get you to say that your exhaust is louder than stock. I've had this happen before... luckily I knew the law and didn't say anything. The cop let me go with a warning ;-)

If they don't get an admission then they will have to prove that your exhaust is louder than stock. So they'll need some sort of proof. This will likely have to be decible levels of a stock exhaust on your car compared to decible levels of your exhaust on your car. Nearly impossible to prove with the limited resources PD's have.

While the officer can say he *thinks* your exhaust is louder than stock... a few simple cross examination questions will quickly poke holes in that. An officer clearly is not an expert in exhaust notes of all cars.

So while the law doesn't require decible levels, the police will still need some sort of decible levels as proof. They know this, so they try to get you to admit to it.

ticket every time
