Whats a better header?
a 4-1, or a TRI-Y (4-2-2-1)
just wondering which ones better and what the difference is?
 
yeah i know 4-1 is high end, and 4-2-1 is low end but wat is the tri-y (4-2-2-1) is it like mid

This is what a tri-y looks like compared to a 4-1. just locate a dyno for 4-2-1 if you want a full comparison (google images is great).
 
Very bad comparison IMO. In general; given similar dimensions, the 4-1 has more top end than the 4-2-1/tri-Y; with the 4-2-1 having better mid/low.

With different designs, diameters, bends, etc. it's pretty much negligible.
 
true yeah i mean its going on a b-series, so i was just gettin opinions on what one i should get
the 4-1 or 4-2-1 tri-y
 
Tri-Y looks sick, and it seems a lot of people use them for high power N/A motor builds.
