Michigan Introduces Bill to Ban Most Aftermarket Exhaust Systems

Legislation (H.B. 5726) to prohibit motor vehicle repair facilities from modifying an exhaust system to “produce noise in excess of OEM stock decibel levels” has been introduced in Michigan.  Under the bill, a person who violates this prohibition would be forced to pay a fine of $10,000 for each violation. 

We Urge You to Contact Members of the Michigan House Transportation and Infrastructure Committee (List Below) Immediately to Oppose H.B. 5726

  • Under Michigan law, a motor vehicle repair facility means “a place of business which engages in the business of performing or employing persons who perform maintenance, diagnosis, vehicle body work, or repair service on a motor vehicle for compensation . . .”
  • H.B. 5726 does not provide repair facilities with decibel readings on factory-installed exhaust systems.
  • H.B. 5726 ignores the fact that aftermarket exhaust systems are designed to make vehicles run more efficiently without increasing emissions.
  • H.B. 5726 would make it impossible for hobbyists to replace factory exhaust systems with durable, better performing options.
  • H.B. 5726 would saddle violators with excessive and unreasonable fines.

DON’T DELAY!  Please contact members of the Michigan House Transportation and Infrastructure Committee immediately to request their opposition to H.B. 5726.
