i looked on here but i couldnt find anything. maybe its just me. i really would like to find a how to on these installs b/c i like doing the work myself and i dont want to pay someone to work on my truck. they are long tube headers and i know i will need gaskets...will i need to do anything for the o2 sensors? thanks in advance

 

If they are the Kooks/JDM version the driver's side goes in from the top and the passenger side goes in through the fender well. New factory Ford gaskets are a must. O2 extenders will also be needed. Watch your starter wires and the main harness going to the trans. If not secure and routed proper they will burn through.

Driveshaft should be easy. Undo 4 bolts where the shaft meets the rear end pinion, but make a mark so it bolts back up exactly where it was.

I'm thinking Cometic makes new gaskets too, good gaskets and bolts a must. I'm planning on a set soon myself when I get the Dyantech's.
