Vermont Bill Would Penalize Some Aftermarket Exhaust Systems

SEMA is opposing legislation to ban motor-vehicle exhaust systems that increase the noise level above the level emitted by the originally installed system. Under the bill, violators would not pass the state’s required inspection. The bill does not provide an opportunity for vehicle hobbyists to install and use aftermarket modified exhaust systems that meet an objective 95-decibel limit under a fair and predictable test.

In addition, the measure does not supply inspectors with an enforcement standard, allowing them to make subjective judgments on whether an exhaust system increases “the noise emitted by the motor vehicle above the level emitted by the exhaust system as originally installed.”
