4-1 header vs tri y

or an itr cat.

I was going to get the rmf narrow at first but I looked at some dynos and even though the tri y dropped off before the 4-1 there were still very close and the tri y looked better all around. My mods are :

Intake exhaust fuel rail with reg intake manifold throttle body URL filter type r cams and other small things. So which header would you choose for my set up For drag racing

Again either one but for drag id go 4-1.

My full Hy Tech setup includes a cat, just letting the OP know hybrid header systems with cat's do exist, if he must have a cat for his state's inspection standards.

Hytech offers headers with integrated cats?
