Which header has the best results, companys??? 4-1 or 4-2-1??? for a GSR, that great header test was on a Type R, and the search didnt healp, so can someone please help me, im trying 2 not waste my money on this, please help, TIA...

 

In this case, what`s good for the R is also good for the GSR.

 

r u goin all-motor or just want some quick power while you save for FI? if thats the case, 4-2-1 yields better midrange and torque.. but if your gonna be racing go with 4-1 since ur gonna be in the top end most of the time. company wise, how much you lookin to spend? i say JDM DC SS 4-1 or JDM ITR header

 

im going all motor..

 

JDM 4-1 or Comptech 4-2-1

 

Toda 4-2-1

 

the people with GSR's please tell me what u use, i am trying 2 figure out 4-1 or 4-2-1, i wanna gain more then 1 or 2 lol, cuz some people say if i put one on their it might not give me n e and if i put the other one it will give me a good gain, please help...

 

Well if you have an LS you want a 4-2-1 header because the power in the LS is in midrange low end and midrange, but if you have a GSR you want a 4-1 header because its power is in top end, where the GSR is the strongest.

 

From what I hear, either DC JDM 4-1 or JG/Edlebrock ProFlo header which claims to make more hp than the dc. They independently tested a 95 GS-R with an intake and stock exhaust and it made like 8-10 more hp than the DC Sports header...Plus they use it on their all motor Integra.

COMPTECH 4-2-1
JDM DC 4-1
