You may use the following points in your message:

  • H.B. 225 provides no test by which vehicles would be tested.  Many states have established noise limits for modified exhaust systems based on an easy to administer objective test standard (SAE J1169) to a fair noise limit of 95-decibels.
  • H.B. 225 would force inspectors to fail vehicles for violation of an unspecified test.  
  • H.B. 225 ignores the fact that aftermarket exhaust systems are designed to make vehicles run more efficiently without increasing emissions.  
  • H.B. 225 would make it almost impossible for hobbyists to replace factory exhaust systems.
  • H.B. 225 provides for substantial fines, including $200 for the first violation, $300 for the second violation and $500 for the third and each subsequent violation.

Overview: Legislation (H.B. 225) to provide that no motor vehicle muffler or exhaust system shall emit a noise level greater than sixty decibels was introduced.  The bill exempts those mufflers or exhaust systems installed as original equipment.  The measure will be considered by both the House Transportation and House Judiciary Committees.
