NOS Factory 5.0 Catted H-Pipe F/S February 19, 2013, 06:28:03 PM I've got a NOS catted h-pipe for sale. It's designed to fit 87-93 Mustangs, but will fit Fox T-Birds and Cougars if you install factory 5.0 Stang headers. This h-pipe comes with the air tube that connects the air pump on the engine to the h-pipe. This WIILL NOT FIT an SN-95 Stang.I'm selling this h-pipe for $150 plus shipping. That's less than half the price a Ford parts department would charge for it. Quote Selected
