Ok, I tried a Pacesetter header and I felt a difference. I know Pacesetter is cheap, the paint burns off and it doesn't fit all that well, but it's decent. Cost me maybe $180, but I've seen it for a lot less online. It gave me more torque which it is designed to do and that's why I bought it. I faired well against a certain car but felt I had no top end compaired to him. I don't worry about top end as much since torque makes driving fun around town.
