As to making the exhaust come out faster, what happens when it gets slowed back down through the cats and exhaust pipes?

It's all in how you phrase it. If normal headers give you 20-30 rwhp, and stepped headers give you say...5-10 more HP..then that is 30% more power. Thats a lot for only a $200 premium. People spend $300 and $400 on intakes that barely give that much power.
