The Momentums are the only shorty I would buy. If you are dead set on having headers, want to keep your existing exhaust, and run HFC's, buy the Z1 (Momentum) headers and HFC.while you are at it, just buy their whole power mod and call it a day. You will get a healthy increase in power. Just don't say we didn't warn you on the install, it's terrible and cost of labor is running about $800.
