I'd like to know what you guys recommend in the way of headers for the 5.0. I want something that is of high quality (like QTP or Kooks for LS1s), but also good gains.

What are you planning on doing with the car? Drag racing? Forced induction? All motor? High end? low end? daily driver? weekend warrior? race car?

Mainly for a daily driver when the weather is nice, so it has to be streetable. But I also want to take it to the strip when I take my T/A and I figured my wife could drive the Mustang down the track...so I'd definitely like more power than what it has stock.
