hey guys i was wondering which header would preform better on my b18b1 thanks

 

Two Peice or not?

 

ya two pecice

 

might want to provide more information on your setup for better responses. Are you stock or what mods have you done?

 

ive had both on my car and the difference in performance is so slight if you dont have any other mods on your car. all i really noticed was that my car was louder and since i dont bother taking it to the track, because i dont want to drag race the car, i dont know if it did much at all. my car still seems and feels like a 15.5 second car.
you should go with a one piece header because a friend of mine got a 2pc 4-2-1 ceramic header and after a year, it warped a bit and didnt seal too well and exhaust fumes were coming out of the space where the header connected. you dont have to take my word for the info above, use your own judgement.

 

No header, turbo manifold. Headers don't do anything.

 

I've had the 2" collector ones in both 4-1 & 4-2-1. The 4-1 hangs pretty low and I smashed the **** out of it. Performance wise, I think the 4-1 took more clutch to get it moving from a standstill, but it did rev faster after 4k. I never had this motor tuned though... maybe it would have helped. We all know that unless you are doing major work on a B18B, if it isn't a turbo manifold, it will still be slow. Listen to mrdeadman.

 

junk the DC headers. they dont do a damn thing. i would personally get a set of used cams

Although you have made a factual statement, that isn't want he asked... lol

Get turbo or vtec... or turbo & vtec.
