I got a 2004 up-pipe for $50. I an having the recirculation flange welded up. I also have an old EGR valve that I am welding shut. My EGR system delete will be the up-pipe swap and the EGR "plug".

Mark, do you even need to mess with the EGR valve if you block the exhaust flow?

Depending on your model year you can: a) unplug the EGR with no issues or b) use a SCT with custom tunes to prevent the CEL or code.

I am also welding up an EGR valve to be cautious. Since I am not planning on removing the EGR cooler (or even welding it up), I wanted to be sure that an EGR cooler coolant leak would not get into the intake through a weak EGR valve (even if it were in the "commanded closed" position).

DSMMH - I appreciate the suggestions. I am not too worried about the EGR valve. It is an old style and a spare. I would not install it in the truck anyway. I will say that the friend who I asked to weld the valve is worried about warping it while welding. So I may be back to the epoxy idea. What type/brand of epoxy did you use?
