273 manifolds

Has anyone seen a dyno test on the new TTI early abody headers?

That would be a cool test, 273 early manifolds,
vs the new TTI headers,
especially, if they also tested the "Spitfires" too. :)

I would like to also see the Dougs headers tested as well. They really are well thought out and they WORK! Very few problems compared with some other designs.
