which headers?
 

:confused: hey guys i need some help does anyone know anything about hedman chikara headers? 4-2-1 one piece....or of R1 4-1 headers one piece...i need some help determining what would be a good choice...if anyone knows the stats on these guys or anything i would appreciate it...thanx!

those are crap. spend a little more and get a set of dc.

ok but what kind of numbers are we talkin here?

take a look at: http://www.ap-engineering.com/header.html

it gives some numbers on different headers. note that only one of these headers is street legal here in the US (comptech 4-2-1). this is just to give you an idea as every car and engine is different.

I got a set of stainless DC 4-1 headers for about 350 a little more than a year ago. I'd reccomend them. I just checked wholesalehyper and they got them for a hair over 375. Might wanna look into that.

thanx guys i apreciate it

if anyone else knows anything about these headers i'd appreciate some tips or what not.

All of the JDM headers(Toda, Mugen, OEM JDM 4-1, JDM DC, etc) have a 2.5" collector, and will not bolt up to your stock cat. You will need a 2.5" cat, and have a flange put on it to match the JDM header if you choose to run one. You can have this done at a muffler shop, or purchase a cat pre-made to fit JDM headers:

As a general rule 4-2-1 headers give a bit more torgue while 4-1 give more top end HP. Same applies to pipe size, smaller more torgue, larger more top end HP.

u think i should concentrate more on top end hp or on torque? u guys gotta help me i'm still a beginner...a novice if u will...lol
