4-1 or 4-2-1 Header? What is the Dif.?

[JB68]

Hello,
I have a 95? LS SC?d running at 7-8 PSI and i would like the help of you guys selecting a proper header. I don?t know what is the difference between the 4-1 header and the 4-2-1 header. Someone told me that the 4-2-1 header help the engine at the low end of the RPM range, and that the 4-1 Header helps the engine at High end of the RPM range. Can someone show me some light on these matter?

Thanks

Engine's only make torque. Do you want the torque added to lower rpm's, or higher rpm's.

Many people say the 4-2-1 is better for forced induction, becuase the shorter primaries (the front part of the header) works better.

I Have Automatic Transmission, so i think i need Torque at low RPm?s to have a better launch.
