But what does improve?

Roddimus Prime

power curve smooths out with much better top end power. DaveB uses the Obx header on his automatic p5 and claims he picked up almost 8mph in top end with that as the only mod.

4-1 design improves top end power with slight increases across the rev range. 4-2-1 increases the whole range also but with more mid-range power and less top end.

You can find headers for 3rd gen Pros on www.protegegarage.com
I think they're made by OBX. Anyway, you should check 'em out. They got a lot of parts for Mazda owners.
