Tight LSA/Tri-y headers, Why? I read this in a thread:
"Tri-Y headers are good for NA cars with a cam of increased overlap?"
could anyone explain to me why this is?

here would be your answer:

they basicaly center all the pulses on a 180* center.... meaning more even pulses...meaning more power..... and the more overlap you have the less even the exhaust....so you can get things back to more even with a tri-y-header

Actually this statement on its own means nothing. Any 4-1 or 4-2-1 header that facilitates increased air flow over a stock manifold will benefit any cam.
However, a 4-2-1 header supposedly provides more "suction" as it "pulls" air through the cylinder. With increased overlap, that will aid in sucking more air during intake.
