Exhaust (or any performance part) manufacturers base their claims on modification levels. So, the part above gains an estimated 5 hp (with little or no other modifications) to 15 hp (very heavily modified). To get the 15 hp, you would need a long (and expensive) list of other mods that directly complement the exhaust and its performance- at that point, I don't think you'd be as worried about the cost of the muffler, but on the flipside, custom exhaust work would probably be of better benefit to you, anyway.
