Abstract

An article of manufacture includes a rigid plate, first and second tab members defined by a pair of substantially diametrically-opposed U-shaped apertures within the plate, and a third tab member defined by a U-shaped aperture proximal to the first and the second tab members. The article of manufacture can be used as an active exhaust defeat device, providing the capability of locking a butterfly valve of a vehicle active exhaust system in a desired orientation. Although the butterfly valve is locked, which may be a non-standard exhaust configuration, the article of manufacture provides that vehicle error codes specific to an exhaust valve actuator are avoided.
