This is said in the May issue of Muscle Mustang and Fast Fords on page 116 about the S-197s. Wow if that is the case why didn't Ford do this in the first place. Anyone ever heard of this? My local Mustang shop said that before Ieven read this in the May issue. This is really news to me. Anyone?

please explain further. I know without cats you are getting more performance however it said with cat-backs and x-pipe. Meaning no axlebacks but catbacks and x-pipe.

Yeah UPR and Pypes claims 20 with the x-pipe but no cats. It's more like 8 to the wheels.
