I got a header for my other car the other day. I didn't know it was a 4-1 till I got it. Anyways. I read the FAQ about the differences of the two, but is that true for all 4-1's? Can some one give me a good comparison of the two for any car?

well...what car do yo have them on....most 4-1 are for high reving engines...but ive seen some civics with some. so i dont think you will have a problem.

lol..its not for a high rever..88' dodge 2.2
general rule is that 4-1 headers are good for upper PRM gains.
4-2-1 are good for lower and a little for upper HP gains.
