i am sure this has been covered but i couldnt find it anywhere..

whats the difference between a 4 to 1 header and a 4 to 2 to 1 header.. i know one had better high end and one has been low end power.. but i cant remember which is which... thanks

4-2-1 better power low and some top 4-1 way better top end

well I had 4-2-1 and I thought my bottom end got worse. I think that the 4-1 is better for bottom end. NOT REAL SURE?

i ended up purchasing a 4 to 1 header form SSautochrome and it is great. i noticed alot more top end power. its laggy for lowend, but once you get mid range to upper you can feel the increase in airflow.

Stock manifold is 4-1. I put on the DC Sports 4-2-1. I feel a pretty nice amount of extra pull throughout. Especially mid range and top end. People claim B.S. so maybe my ass dyno is broken?
