In the pursuit of figuring out which exhaust to go with for my truck (leaning toward the Mufflex dodm80), I started wondering if anybody on this forum has been pulled over for having an excessively loud exhaust (especially the dodm80!). Just curious. And just to clarify now, I am not looking for f the police retorts... I live in Michigan and the law here is pretty clear:
257.707c Noise limitations; prohibitions.
(1) After April 1, 1978, a motor vehicle shall not be operated or driven on a highway or street if the motor vehicle produces total noise exceeding 1 of the following limits at a distance of 50 feet except as provided in subdivisions (b)(iii) and (c)(iii):
(i) Ninety DBA if the maximum lawful speed on the highway or street is greater than 35 miles per hour.
(ii) Eighty-six DBA if the maximum lawful speed on the highway or street is not more than 35 miles per hour.
(iii) Eighty-eight DBA under stationary run-up test.
(3) A person shall not operate a vehicle on a highway or street if the vehicle has a defect in the exhaust system which affects sound reduction, is not equipped with a muffler or other noise dissipative device, or is equipped with a cutout, bypass, amplifier, or a similar device.
(5) A person shall not modify, repair, replace, or remove a part of an exhaust system causing the motor vehicle to which the system is attached to produce noise in excess of the levels established by this act, or operate a motor vehicle so altered on a street or highway.
