Ok.... GSRNBP on aim(oisin on here?) is telling me that Dc sports headers suck for integras....

Another question I have is, will a 4-2-1 1 piece header for a GSR fit on my b18b1 LS/GS motor? Cuz dc sports doesnt seem to make a 1 piece 4-2-1 for my ls...

I think they made it that way because the motors are a little different. You could try and see if it fits and then if not....well i guess that would suck.:licker:

in so many words, the gsr header will bolt up to your head but it wont bolt up to your cat because it's shorter.
