There is a House Bill that we the car community must ensure does not pass. It's House Bill 5543.

Long story short if this bill passes it could result in a frenzy of excessive noise tickets, gross neglect of our state's tax revenue, and quite possibly hurt small exhaust / performance shop businesses.

URGENT LEGISLATIVE ALERT

Michigan Bill Would Ban Most Aftermarket Exhaust Systems

A bill (H.B. 5543) to ban vehicles equipped with replacement exhaust systems that differ from the design specifications of the original muffler has been introduced in Michigan by Rep. Rick Jones (rickjones@house.mi.gov). H.B. 5543 would also prohibit the sale and use of exhaust systems that exceed an 80-decibel limit at a distance of 50 feet. The bill has been referred to the Michigan House Transportation Committee for consideration.

In some states, noise limits for modified exhaust systems are established by a SEMA model bill and applicable to an easy to administer test standard. The SEMA model provides for the testing of vehicle exhaust noise to a standard adopted by the Society of Automotive Engineers (SAE) with an established noise limit of 95-decibels (SAE J1169). Under the SAE standard, a sound meter is placed 20 inches from the exhaust outlet at a 45 degree angle and the engine is revved to three quarters of maximum rated horsepower. The highest decibel reading is then recorded.

To date, with the popular support of vehicle enthusiasts and related businesses, the model has been enacted in California, Washington State and Maine. This year, the SEMA model was introduced in Virginia.


We Urge You to Call or E-mail Rep. Jones and Members of the House Transportation Committee (List Below) Immediately to Oppose H.B. 5543


H.B. 5543 ignores the fact that aftermarket exhaust systems are designed to make vehicles run more efficiently without increasing emissions.

H.B. 5543 fails to recognize that aftermarket exhaust systems offer increased performance, which can make a vehicle safer by improving its ability to merge, pass, travel uphill, etc.

H.B. 5543 would make it impossible for hobbyists to replace factory exhaust systems with more durable, better performing options.

The SAE J1169 test is performed in a controlled environment that limits the amount of ambient sound (e.g. from other cars) that might skew the results.

DON�T DELAY! Please contact members of the Michigan House Transportation Committee immediately by phone or e-mail to request their opposition to H.B. 5543. Please e-mail a copy of your letter to stevem@sema.org. Thank you for your assistance.

Dear Michigan Representatives,

Bill 5543 has recently come to my attention. I would like to express how displeased I am with this legislation. I feel Michigan does not require blanket legislation like this. Noise ordinances should continue to be taken care of locally (city, township, etc.) and not state wide.

I feel if Bill 5543 were to pass it would negatively effect local small exhaust and performance shop businesses. I also find it near impossible to accurately test for infractions considering the procedure will be used in the field not a controlled environment. Miscellaneous ambient noises (passing vehicles, wind, etc.) will skew results. Lastly, I find it a complete and utter waste of tax dollars (which will be required) to purchase testing equipment and train personnel if Bill 5543 were to pass.

I sincerely hope Bill 5543 does not pass and you'll find many people agree with me. Please take the time to view a petition I've started regarding Bill 5543.

You're voice DOES matter!

p.s. I would sincerely appreciate if this could be stickied

This was taken from Xceedspeed...I just copied and pasted...

Nice work Pete

80 dB from 50 feet... that has got to be one of the most retarded ideas I've ever heard... so they're gonna have to set up giant building to limit ambient noise for testing if you get pulled over for it.

All the detroit automakers are already getting hit hard... if they take away peoples ability to mod their cars people are gonna be leaving in flocks...

This is lame.

Barge is Screeeeeeeeeeeeeeeeeeeeeeewed!!!! [censored] easy 100db

I wonder what my exhuast is? after all it is just stock
