Indiana Introduces Bill to Require Factory Installed or Equivalent Mufflers

By SEMA Washington, D.C., Staff

Legislation to require all motor vehicles to be equipped with a factory installed or equivalent aftermarket muffler was introduced.

Indiana already requires that exhaust systems be “in constant operation to prevent excessive or unusual noise or smoke.” Among other things, the bill fails to recognize that factory replacement parts or comparables are not always readily available for all motor vehicles and that aftermarket exhaust systems are designed to make vehicles run more efficiently without increasing emissions.
