So I picked my truck up from the dealership today for the ECM relay recall, and they informed me that my exhaust manifold/s had a leak, but didn't really go into detail. They gave me a quote of $2041 to replace/fix this issue. Does this necessarily mean that one or both manifolds are cracked? Or could it be a gasket leak or something else? Anyone have experience with this, and how does that quote sound? High, low, good? Thanks for the help everyone.
