I'm planning on putting on some hooker headers/sidepipes this summer, and I heard people saying that you should check the state emisson laws first, how do I find them?
Thanks for any help!

You should be able to go to any "State of Maine" license, title, license plate renewal bureaus(Bureau of Motor Vehicles, State of Maine) and they should be able to get you a copy of state emission laws.

If your car is pre-1975 then isnt a very big issue, however after 75 is when the catalytic convertor appeared and even if your state doesnt inspect there are federal laws that prohibit modification of that sort. Obviously though, if there is no inspoection then the likelyhood of getting caught doing such mods is low if non-existant

One more question, what would happen if I got pulled over for making too much noise with em, I have no doubt now that I can get them inspected, but would there be a fine or something?

most likely if he is a SOB, eI wouldn't worry about it

I would go to some cruise nights and ask around, or join the local Corvette club, and ask there.



They sound pretty strict there...
Why are exhaust system repairs regulated?

Engines and the associated emission systems are generally affected by the exhaust back pressure. Therefore, the back pressure and the exhaust system configuration (including the location of the catalytic converter and exhaust pipe diameter and length) are "elements of the design" of a vehicle's emission control system and cannot legally be tampered with. Examples of illegal modifications include:

* Installing a dual exhaust system on a vehicle not originally certified with a dual exhaust, or installing a "fake" dual exhaust after the catalytic converter and after the exhaust system has been joined together to a single pipe

* Changing the pipe configuration (such as a side pipe, stack, or short pipe on a pickup)

* Removing a catalytic converter and installing a converter replacement pipe

* Installing glasspacks or small turbo mufflers instead of direct-fit or cataloged replacement universal mufflers


Im guilty of the third one! :blueangel:

Before you put sidepipes on, you should really like them.

You might find this interesting.

FROM http://www.epa.gov/otaq/12-miles.htm
1974
Congress delays the HC and CO standards until 1978 and sets interim standards at the request of the auto industry. Congress adopts the Energy Policy Conservation Act, setting the first fuel economy goals. The Corporate Average Fuel Economy (CAFE) program establishes a phase-in of more stringent fuel economy standards beginning with 1975 models.

1977
Congress amends the Clean Air Act. At the request of automakers, the HC standard is delayed until 1980 and the CO standard until 1981. The NOx standard is delayed until 1981 and is relaxed to 1 gram per mile.
1981
New cars meet the amended Clean Air Act standards for the first time. Sophisticated three-way catalysts with on-board computers and oxygen sensors appear in most new cars.

Thanks for the help guys, I found someone to put an emissions sticker on my car, as well as inspect it. Can't wait to hear that vette purr =)

I understand the inspection with the catalytic converter but I would like to clean and clear up the engine bay are there things that I can take away from my 81 vette without doing much damage? But making it easier to work on and clean.
thanks for your help

You do realize this thread is over ten years old right?
