Hooker builds some really nice headers for the 300. Go check them out. Yes it will use dual exhaust.

I got the 3006cyl headers and 4 barrel intake from Clifford. What they told me is with dual exhaust makes it quiker of the line and with single gives you more top end speed. I used to do alot of highway driving so I went with single.

I am running a Hedman on my mildly built 300 six. The truck gained performance throughout the rpm range plus another 800-1000 rpms of useful power. And not to mention I picked up a few extra mpg!

Are these headers recommended for the Fuel Injected 300? I've got an 87 5-150 and its got exhaust issues. when I do the rebuild in the spring, I want to start at the headers and work back, but want to make sure whatever I do is compatible with the computer/emmissions, etc...
