Should I move this to 7.3 Technical forum? DI up pipes and 4" downpipe are mods but the procedure is probably more tech than mod.

 

I pulled my down pipe when I installed my up pipes. Can't remember if I pulled the starter, I know I thought about it.

 

It will be easier with the DP out of the way. You could try dropping it to see but still think the easier way is to remove it.

 

The time needed to remove the DP is well worth it..

 

Thanks guys.

Got a buddy coming over to help pull while I heat one of the exhaust pipe connections to red with a torch. I bet it will go back together without heating again.

Probably should have had Dave's team install it but I have learned a lot about this engine, and I got the oil from the HPOP leak I had cleaned from the valley.

 

I got both sides unbolted and everything out including the turbo with the dp inplace. But there is no way to get the new pipes in. I tried every angle. Not happening. I fought with the dp for a half hour to get it apart. The uppipes fell right in once the dp was out.
Hope this helps:ford:

 

Are there gaskets between the exhaust manifold and the uppipes? Seems there could be a significant loss of exhaust pressure without them.

Thanks,

 

Nope ball an socket flange it will seal.

 

Next time I do up pipes, my tranny is coming out. There is nothing in the way with the tranny out. I can R&R my tranny in about 90 minutes. I fought the uppies for three to four hours.

 

for real? is your truck 2wd or 4wd?

 

I tihnk I'd re-install stock up-pipes with new donuts before I'd try and do those bellowed pipes again. Things were a nightmare to get in/out and fitting right.

 

I got a set of DI pipes in my truck. Pulled the DP top and dropped them right in, no problems. Worth every dime.

 

Got em done.

The down pipe had to come out. My problem was not removing the spider and turbo but the down pipe. My 4" downpipe and exhaust is Dynamax (PO install) and my propane torch did not have the gusto to heat the connections enough to get them apart.

After messing with it a while and calling Dave at DI, I finally maned up and used my sawsall and got with the program. Cut the exhaust forward of the cross member and in front of the muffler.

Took the down pipe and the 4' section behind it to Tomball muffler and they welded it back together and separated the connection. I bolted the down pipe in and drove the Excursion back to them and they welded the other cut and put it back together.

Bone head move on my part was not connecting the EBPV rod to the pivot. Had to remove the boot on the passenger side and rotate the intercooler pipe up and out of the way to get my hand in there to make the connection.

If I melt the stock turbo I guess I will be doing the EBPV delete when going with a BB turbo. In the mean time the wife will appreciate the quick cabin heat, especially when we are at her folks house and its 20 below at the western tip of Lake Superior.

didn't have to pull my downpipe to install my set. It was a tight fit... LOL

 

:whs:

I think I used a small box end wrench and a ratchet with a swivel head.
