These Pypes hangers are identical in size and shape to the Ford hangers but are made in stainless for a lifetime of use. They should be used when converting a V6 Mustang to dual exhaust. Also Ford made a design change sometime in the middle of the 2007 production of Mustangs. If your car is equipped with hangers that look very different from those pictured here, it will be necessary for you to purchase these hangers for proper fit of any of the Pypes Axle Back products as well as most other aftermarket axle back products.
