Hi, I'm looking to upgrading my header. I have a F22B2 auto with stock manifold on it. What would be better a 4-2-1 or 4-1? Stock it is 4-1. Its my dd but would like to get little more out of it. Please help!

Thanks-Travis!

4-1 is low end. More back pressure causing better acceleration and 4-2-1 has a little bit less back pressure causing higher top speeds. Would it make much of a difference on everything else stock... Probably not noticeable.

KA7 dude is a tard. So its jh4dc.

4-2-1 is low/mid range power
4-1 is high end hp

You want the 4-2-1 will make better power where it counts.
