Default dc 4-2-1 to jdm 4-1 worth it?
i guess my question is, will a jdm 4-1 header fit my b18a, and is it worth it to sell me dc 4-2-1 header for the 4-1. what kind of gains am i looking at. i heard that dc also made 4-1 but im getting a good deal on the other. thanks in advance

Hangs really low but its worth it if you can get it on a good deal.

More high-end power, lose a little low-end, but on average the gain is more...

4-2-1 is a better header, but its hard to see the gain unless you have a dyno
