Vibrant Performance has engineered flexible couplings that can isolate vibration from your vehicles engine which relieves stress on your exhaust system. These couplings feature an internal stainless steel interlock liner that incorporates smooth flow of high temperature exhaust gases. TurboFlex couplings are recommended for high performance applications, especially forced induction applications. One of the main advantages to these flex couplings is they will reduce premature cracking of manifolds or downpipes and extend the life of other exhaust components.
