Yes, MUCH "truth" to it. In fact, 3-tube headers are strictly for "bragging rights" and don't "make power" as headers are supposed to. Isoloation of the exhaust pulses and vacuum "signal" is the "purpose".
Hooker headers are the "best" for power productoin, at least as far as "out of the box" headers are concerned. The consideration there is ground clearance. Hooker "Comps" are fine, but 1 5/8" in diameter. If not trying to make more than 500 HP, that's enough.
Doug's Headers are also very good. They offer some "special" part numbers Hooker doesn't (not your application, as Hooker has that one "covered").
Mad Dog is a relatively new brand that is excellent.
Which ever brand you buy, get them "uncoated", as the ceramic coating applied by the header companies won't "live" for more than a year or two. Have them shipped to a coating company and have a "thermal barrier" applied. We use Thermal Tech in Hopewell, Virginia. They're also a Doug's "dealer", so "one stop shopping' is available there. Jet Hot and Swain are two other coating companies that come to mind for high quality.
