Each kit comes complete with quality hardware, gaskets and instructions for a complete installation.
Direct replacement of the stock exhaust manifolds, header bolts up to the existing stock Y-Pipe/Crossover pipe. Installation requires modification to exhaust system. Takes between 3 And 6 hours depending on application. All hardware, gaskets, and instructions included.
