Angry Aftermarket Exhaust Illegal in NH

I just heard that by the end of this month New Hampshire is going to outlaw all aftermarket exhaust systems. So only OEM parts are legal on the car even if its not loud. What can I do about this? Is there a pipe with a factory-looking muffler I can get? Or are there any exhausts that sound close to stock but still make power? This is some ****ed up **** right here!

p.s.- where can I get the old school subaru door-chimes?

If it is true then they are likely going after the "obvious", loud, obnoxious, 6" exhaust tip, etc. exhausts, and by "OEM" they mean a replacement for the factory unit by an alternative manufacturer, so Pep Boys and Midas will still have plenty of buisness.

But if they use the letters OEM....which means original equipment manufacturer,which none of the midas et al stuff is, the mufflers would have to be the same pieces that are offered on the car when new.
I would suspect that they are going to enforce some type of decibal law. That is the only realalistic way of doing it.

Where exactly did you hear of this law? I live an NH and haven't heard anything about it. Right now we don't even have Emissions testing for crying out loud.

Ok I found it. I think. It does not say anything like what you are saying. It is strictly a Noise level thing.

Bill Text

III. No person shall modify the exhaust system of a motor vehicle in any manner [which will amplify or increase the noise emitted above that emitted by the original muffler installed in the vehicle and such original muffler shall comply with all the requirements of this section] so that the exhaust system emits noise in excess of 95 decibels as measured by the Society of Automotive Engineers (SAE) standard J1169 (May 1998). No person shall be in violation of this paragraph unless the director proves that the exhaust system modification results in noise amplification in excess of 95 decibels under the prescribed SAE test standard.

A very similar law is on the books in other states. I think WA state already has this law.

i got pulled over for my greddy evo, not because of the sound, but because he pulled me over for my tint. he couldn't get me on the tint (i have a medical waiver) so we went on to the next fishy thing, which was my huge exaust.

i showed him the certificate that greddy provides with their exaust systems, which states it is 94 db and tested/certified. he told me that ANY modified exaust is a ticket... he wrote me a warning and i was on my way, however...

the rsa listing states that you may not MODIFY your exaust to amplify noise or reduce (or increase) emissions. i did not MODIFY my exaust, i REPLACED it, two very different things. i now have a print out of that rsa in my car, and if you read it word for word, the cop was wrong. won't stop them from giving you a ticket but it should hold up in court.

the rsa says nothing about putting an aftermarket exaust on your car, it says you can't hack it up or use a straight pipe.

if a cop wants to be a dick, he will be period. doesn't matter what the book says (coming from someone who used to hold cops with very high respect). if you owned a harley or a v8 mustang and had NO exaust you would be fine, but since you drive an import...


i'm leaving now, i will start ranting 5 pages long...

and check at the bottom of that new law, it takes effect jan 2004 and states:

no person shall be in violation of that law if the defendant had reasonable grounds to believe they were not in violation of the law.




cop: "sir my reading says 130 db"

redneck: "WHAT!?!?"

cop: "I SAID IT READS 130 DECIBLES!!!!"

redneck: "SORRY I CAN'T HEAR YOU!! I THOUGHT IT SOUNDED FINE!!!!"

cop(writes down on a pad of paper): "ok, well it is american made, off you go you cute little scamp!!"


by the way, my greddy purrs like a kitten!!!!

In Maine, they just passed new exhaust and suspension laws, that are similar to what you posted about NH, with one exception:

Exhaust:

You are now allowed to put on an aftermarket exhaust as long as it does not exceed 95 decibels and as long as you obtain a certifate from your local inspection station and pay the $20 fee to register it, annually.

Bill Text

Bill Status : Signed into law by the Governor

Suspension:

You will now be allowed to lower your car just above the bottom of the rim. I guess 30 series tires will become popular?

Is there a rpm range for decibels? Shift st 2000 rpms and it should be no problem. That is probably a simplistic approach but I don't have sound restrictions here.
