which dc sports headers would be best for my 1999 integra gsr...the 4-2-1 or 4-1 wats advantages/disadvantages for both?? thx

dingus88

dopends what you want...I personally woudl go jdm 4-1 with a full 2.5 inch all the way back..jsut so future all motor power adders like cams will be put to full use..the jdm 4-1 2.5 collector and 2.5 exhaust is a proven basis for all motor power...but if your just going for i/h/e then just get a 4-2-1 with 2 1/4 all the way back for mild all motor apps..the 4-1 wodul be over kill if your jsut doign mild bolt on's

4-1 higher top end
4-2-1 higher midrange

4-1 for me...

thats what i wan't if i decide to go n/a

boy_huot

yea for this summer it will be I/E/H for me...and lowering my car...but in future if i have money then for sure a little more so 4-1 wud be my best bet??

4-2-1

nice midrange power..... something we need to boot around the Bseries motor.

but the GSR has some pretty good low end Grunt, so id go 4-2-1

boy_huot, if you're smart you'll ignore what all these ppl said and you'll go look at dyno charts and decide for yourself.

don't expect the RIGHT answer to be handed to you... ppl will have opinions from what they HEARD and so on, but dyno charts don't lie.

bbarbulo is right dyno charts dont lie but if your car is extremely lowered the a 4-1 is not for you so keep that in mind but if its got a mild drop then you should be ok

boy_huot

ok dude jus lookin for some opinions

boy_huot

oo by the way 2 inch drop for front, 1.75 back
