New Hampshire Signs into Law Bill to Allow Use of Side-Mounted Exhaust Pipes

A win in New Hampshire! Governor Chris Sununu signed into law SAN-supported legislation (H.B. 1534) to authorize the use of side-mounted exhaust pipes for antique vehicles. The new law specifies exhaust discharge points (must be to the rear edge of either door if the vehicle has 2 doors and to the rear edge of either rear door if the vehicle has 4 doors) and such system directs exhaust gas away from the vehicle.

Prior to the new law, only custom vehicles were allowed to have a side-mounted exhaust system. Additionally, the new law recognizes that the collection and restoration of historic and classic cars is an important part of preserving the technological achievements and cultural heritage of the United States. It will go into effect July 19th.

Congratulations and thank you to those who supported this effort!
