N/A build discussion

#137156 just wondering how everyone rates the comptech 4-2-1 header, my build is going to be

blox stage 2 tuner cams
blox springs and retainers
skunk2 tuner cam gears
skunk2 68mm throttle body
skunk2 68mm intake manifold
standard JDM b16a engine
decat
2.5 greddy evo2 cat back
mapped on chrome or something similar

then possibly in the future a b20 bottom end

will it be one of the better headers to go for on this build or should i look for a different header, maybe a mugen or something else.

im not bothered about brands. i only look for performance in products

#137193 thats a good header, i would look into some other cam/springs/retainers like skunk2 or even crowers. somethin other than blox

#137239 i did some research into the blox cams and there the same as the skunk2 stage 2 tuner cams, plus i've already brought them.
