There are many who will repeat this concept that headers don't mean anything on the time slip. It depends as always.

Had a decent set of headers we made then had a custom set made for the engine combo picked up several MPH and decent amount of ET back to back.

Friend of mine went from a set of box headers to burns stainless design and set of their collectors picked up good amount of ET and a few MPH.
They were told clocking the primary tubes was more important than equal length plus avoiding sharp/tight turns was also.



Depending on how far out to lunch your present set is you could pick up a lot!
