typeR aus spec oem header vs after market

[locote]

are type R headers as good as after market 4-2-1 headers, what kind of gains would i see in a 96 gsi and what would be the best exhaust diameter to get in press bent??

or would 4-1 headers be better, i know they are mainly for top end power. how would they work on a non vtec motor which redlines a 7000rpm. does any one have any experience.

auspec type r headers are susposedly the same as my vtir headers so yerr i dont think they would be that good and as adrian from toda au said if u aint got the money go for x-force headers they would be equal to jdm headers but for half the price....or something like that...
as for diameter of zorst type r's run 2.25 or there aboutz and pplz say max diameter for a b series is about 2.5 so yerr not much room to work with but atleast you roughly know whats best....

aus spec itr headers are junk, heavy and ugly POS

What about JDM 4-1?

[locote]

does mandrel bends make much difference if i put xforce header and 2.25' zorst

[locote]

i got told that b18c headers wont fit a b18b is that true, i wanna get the 4-1 headers from xforce

[locote]

so would it make much difference in power getting the jdm 4-1 or xforce 4-1 as oppesed to aftermarket 4-2-1 not aus typeR??

[quangsta]

mandrel bends susposedly give almost a 50% better air flow rate as oppose to crush bends, not sure if crush bends are the same and press bends but yerr main point is mandrel bends make a difference....so ive heard =)

can some 1 please help

[faijai]

depends what ur after
4-1 better top end and can feel the bottom end lagging on the jdm 4-1's
4-2-1 better bottom to mid end power.
jdm 4-1 headers r good and go for n e where form 650-800.
aftermarket gof rom n e where from 300-1500
