F series vs. E series 7.3 Diesel downpipe

We want to upgrade the exhaust on this E550. I know the motor is the same, but obviously its in a different location because of the E550 being a Van chassis. Does anyone know if a 4" F series downpipe work on a E series body style.

Well, it looks like you are in Mfg so you can make anything fit, right?

Honestly, I believe the answer is either no or at least not without some modifications. What I do know is I have an E-series turbo on my F-series PSD and I had to use an adapter to get the F-series exhaust to bolt up to E-series turbo. Clear as mud? What year E550? Does it have the EBPV on the turbo? That is the big difference in the F-series and the E-series turbos I have had.

Its an 03 E550. Ya we can make a lot of things work, but if i can buy something and save me 3-4 hours its worth it. Rather be workign on things we do everyday rather then rigging something up. We haev a tubing bender but not a 4 inch die set. And I am not about to buy another 1000 dollar die to build one down pipe.

Do you know of any Van diesel sites that may have something like this?

Don't know what the "EBPV" is.

I think the F-series downpipe will work if you use the adapter like DI sells for putting a van turbo on a pickup. It eliminates the EBPV(exhaust back pressure valve) though. I think you could weld a new flange on the turbo to make it fit also and keep the EBPV, that's how they used to do the van turbo to pickup swaps I believe.
