Mad Dog Headers

You 'may' have your points but 2700+bucs aint logical man,cant be right in the head,there aint no way to justify it

Maybe for YOU but it is perfectly logical in context as Inkjunky and A-body Joe have pointed out. It's as basically heads up racing and there is more power to be gained in exhaust than probably anything other legal modification except perhaps the shape of the cam lobe.

For other forms of competition whether it is worth it is still worth considering. With any given engine, exhaust is one place where large gains can be made. I can tell you that over the years I've wasted close to that much in cash alone for headers that didn't work out either immediately or in the long run.

Are these a tuned header?

A tuned header refers to creating harmonics that helps fill the cylinders with clean intake air through certain rpm ranges. To do this, each primary tube will be of equal length. In a stepped header, both the intial and stepped up section will be of equal length. That's only part of it, but its the part that when you look at the #1 and #2 tubes pictured its obviously not a tuned header.

On a street vehicle, in my opinion it is more important not to accidently create bad harmonics in the system. That is, to insure that harmonics are not occuring that reflect exhaust gas back into an opening exhaust valve. A software program like Pipe-max can make sure H or X pipe placement, muffler placement, overall length are not placed harmfully. The lengths closer to the engine are generally the most important. So if the primaries are unequal, and the collectors* are unequal, problem harmonics are going to be less of a big deal.

*In a closed exhaust consider collector length the distance from the end of the primary tubes to the muffler, H-pipe or X, whichever comes first.
