what is the difference between these headers?..
 

what is the difference between a 4-2-1 header and a 4-1 header?

do you gain more power with one of them?

and does it matter if it is a two piece or a one piece?

thanks

well 4-2-1 is known for good low/mid range and iight top and 4-1 gives u good top end.. just on what u want bro

4-2-1 is for low to mid power

4-1 is for high power (DC Sports claims no loss in low to mid)

1 piece is lighter than 2 piece

fyi search before posting this.
