As reported by SEMA, through its government affairs division, a "substitute bill to ban the use of most aftermarket exhaust systems has been introduced in the Utah Legislature and passed by the [state's] Senate Transportation Committee," and will move "to the floor of the senate for a vote by all members. Under the substitute bill, all vehicles must be equipped with an exhaust system that is 'installed by the original manufacturer of the vehicle and is not modified; or meets specifications equivalent to the muffler installed by the original manufacturer of the vehicle and is not modified.'"
