i would guess they are gonna pretty much be the same. if so the difference will be negligable.

Default 4-2-1 vs 4-1 header



The 4-2-1 is just what it says...4 pipes into 2 pipes... then into one out to the exhaust. It separates the exhaust flow a little more and might give u a few more horsepower (maybe 1 or 2 tops) . 4-1 is 4 pipes directly into 1 pipe... </P>


Its kinda like the freeway, if2 lanes are trying to mergeat the same point, its alot easier on everything than 4 lanes trying to merge, does this make sense?</P>


If u can afford it... go with the 4-2-1, but if u are doing minimal mods then the 4-1 wont really hurt anything.</P>

Did you ever go to the start of this original Headers and Exhaust forum, I started it a while ago and posted a 4-2-1 Header in it.
Take a look at it and then if you wish e-mail me back..I'll answer your questions for you..

If you can get the 4 to 1, get it.

I would go with the 4-1, if you talk to any real racer it gives you the better ratios and HP.

the 4-2-1 is better for midrange power and the 4-1 is better for top-end power, if you are into auto-x or circuit racing, go with the 4-2-1, if you are more into drag, go with the 4-1. that said, the difference isnt that big, just try to get a quality header in either configuration
