Our braided flex couplings are great for reducing vibration and stress in your exhaust system. They feature both a stainless braided external and internal layer as well as a flexible stainless bellow in the center. The braided internal layer is meant to prolong the life of the metal exhaust bellow and help eliminate "whistling".
NOTE: These flex couplings feature an inner braid and are not intended to be used in turbo manifolds or applications where the braided flex coupling is positioned BEFORE the turbo(s). Due to the extreme heat created by the turbo(s) and/or the turbo manifold(s) the internal braided portion can degrade and may damage the turbo. Ace Race Parts is not responsible for any damage caused by using this braided flex product in pre-turbo applications or if it is placed in the direct line of induction of the turbo(s). We highly suggest using Flex Bellows with a solid inner liner for pre-turbo applications, including turbo manifolds.
