4-2-1 would be better for b18b b/c of its low redline and by adding a 4-1 you would be losing low end torq and gaining more in the top end. basically, the b18b is not a high revving engine, so 4-2-1.

you need a 4-2-1. ls does not make top end power, so you'll be sluggish and pulling as hard. go w/ a 4-2-1 jg header w/ import builders mod. or you can look around for a jdm header 4-2-1
