I keep hearing everone saying that the 4-1 are "better" than the 4-2-1. This is not completely true. While the 4-1 will help more in the mid/upper rpms & the 4-2-1 will help in the lower/mid it is really not that much of a difference AS LONG AS THE TUBING IS THE SAME DIAMETER. I have seen various dynoes of other cars where they tested 4-1 vs 4-2-1 headers and the difference was usually only 1hp. In fact the 4-2-1 DC headers tested a higher max hp(& torque) vs the 4-1 DC headers on an Integra GS-R. It is almost the same as putting an exhaust on your car that is too big. If the primaries are too big they will not scavenge the exhaust gases as well. If you are building a car that will have ALL the n/a mods you should go for the 4-1 since you will obvious be racing your car so you will want that extra upper rpm hp. On a street car that will maybe have the basics(I/H/E) you could just get the 4-2-1 and save a little cash. This is my .02, take it as you will.

thats VERY true<img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>
if your not gonna go racing and all that stuff, you want that low end to mid torque and don't need that high high end, and if your gonna race then you do need the high end ofcoarse.
good post, that will maybe clear up some of the confusion when it comes to people looking to purchase the headers. two thumbs up for you!<img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0><img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0><img src=/images/forums/snitz/approve.gif width=15 height=15 border=0>
