who has welded there up pipe shut to the EGR cooler?

[barry1me]

I would like to hear from the people that have done this, and how hard is it? I have a hard time rationalizing with paying $150 for one that has it blocked shut.

I had mine done when I got my headstuds installed. It was a piece of cake then as the pipe was already off the truck. I'm with you tho, why spend $150 when you can weld it shut for free. On the flip side, maybe those who want the sneeky pipe are concerned with being able to put it back to stock for warranty reasons? Just wondering aloud.

so if I weld my inside of my pipe shut which would look and function just like a sneay pipe?? If I have to go into the dealership for warranty work would I throw a code if my truck is in stock form and the pipe is welded shut internally?

Weld it.
That way you know it's OFF and can't cause over-pressurization.

I was told by authority, 03' and 04's can have the EGR pipe welded in the proper Location (where the pipe branches off and attaches to the EGR sensor feed) NO PROBLEM !
On 05' and 06' The Same Pipe has an internal Flange that acts as a diverter.
on these NEWER models the same procedure (weld shut) can be performed , but the pipe (EGR) also needs to be cut open in order to remove this internal directional flange. This removal of this flange would ensure that 100% of EGR Air flow by-passes the EGR feed completely. (Not leaving a restriction in the middle of the EGR pipe that would direct partial flow to welded shut Flange.)
BUT>>> This cut in the EGR pipe made to remove the diverter would lead to FORD being able to identify a modfication to the EGR pipe.

So in a NUTSHELL, 03' and 04' weld away with confidence and $avings....
05' and 06' can be done with a little more WORK and they WILL NOT retain the OEM appearannce.

Hope this rings true and makes sense......Good Luck Guys n Gals

Dats true john! The sneaky pipe for the 05 and up trucks does not have the scoop anymore. That scoop blocks nearly 35 or 40% of the flow to the turbo. It truely does make a differance.

I have mine welded shut with no issues. In fact, there is no contact between the up-pipe and the EGR cooler. Valve deactivated with SCT.

good info I think I remember reading that somewhere else. If I have to take my truck into the dealership I can get another stock up pipe.

I had a Bullydog 4" exhaust on my truck at first. Well then I learned that was a bad idea when it put a hole in my up-pipe. I got one from ford for like 100 or 120 bucks.
