This is one of 2 new Cat Back Pipe only kits we now offer. This kit is constructed of 16 gauge mandrel bent aluminized tubing with a 24 inch resonator and is a direct bolt on to your factory downpipe converter assembly or any of our W Body Performance downpipes. After many requests for a cat back system that will bolt on and allow the use of any 13-14 inch case length performance muffler, we developed these kits just for the W Body crowd. This kit was designed for the lightly modified naturally aspirated cars. This kit includes hangers welded to the pipes in the stock locations as well as a custom rear hanger that slips into the factory rear rubber hangers and clamps to the muffler outlet nipple. We even include clamps so all you have to do is choose the muffler you like, Magnaflow, Flowmaster, Hooker, Dynomax etc. in a side inlet, center outlet configuration and you are ready to go.
