extractors..

[denrie]

For an eg with a b18c2 motor what would be the best solution for extractors 4-1 or 4-2-1? and wheres the cheapest and good place to go? (in the west) blacktown, mount druitt area, parra, livo?

you can get xforce or 5zigen headers pritty cheap from some of the traders on here

4-1 headers hp output on high RPM, 4-2-1 headers hp output mid range n low range rpm.

i disagree. i had JDM 4-1s and i gained in low to mid also over my 4-2-1.

thats always a confusing debate, as the status quo generally say that felixd is correct. however theres a huge pocket of people who agree with limbo. wish the sydney folk went through with that extractor dyno test. wouldve laid this to rest once n for all.

i agree but i also understand that some people think (like 'limbo') that 4-1 is better all over. i think it depends on the quality of the extractor but as a general rule, 4-2-1 better for low to mid range.

i have 4-2-1 on my dc2 and i got a noticable gain in those areas

from what i gather i read on here somewhere that a cheap 4-1 header will be better then a cheap 4-2-1, however a top shelf 4-2-1 header is better then a top shelf 4-1.

Just wondering if you have tried both? cos i have. It helps when you have friends who have exhaust shops. Cos i tried a variety of combos before settling on the JDM 4-1s.
But then its up to you what setup you would like, cos i only post what i've experienced

[nick_sixx]

i doubt you would really be able to feel that much of a difference....

I've J's racing 4-2-1.. on a B18C2 feels more torquey than before.. noticeable gains (Not huge).. especially on uphills.. Feels more low to mid.. A decent installation will cost u abt 200+.. (good job no nonsense) ..
