02 Downpipe on an OBS?

[cullumscott]

Saw a wrecked 02 with a 7.3 in it today. The downpipe was danglin by the last hangar, so i asked how much. Guy said 10 bucks, so i bought it.

I held it up to the stock OBS downpipe (made me sick to think that ford thought that one was a good idea... FLAT??!)

Anyways, it looks like 3" at least... so must have some better flow. It had similar bends to it, but looked like the flange was at a different angle.

Im wondering if anyone has heard of the newer DP being used on the older 7.3?

I think with a bit of adjusting, i can make it work.

OR should i just pony up and get a 3" mandrel bend piece?

Get a 2 piece mandrel bent DP. It will save you lots of headaches.

positive it wont work, you probably can sell that downpipe for like 30-50 bucks, sell it and buy the correct 3 inch downpipe for the obs

I've been told it will work but you have to swap the flange from your stock down pipe. It's 3.5" BTW. I have the one off my Superduty and I'm seriously considering attempting the swap now that I have a welder to use.

Thanks for the replies. Im going to order a new one.

Superduty, i dont think its 3.5 ID.. it shrinks down inside, and i bet its not even 3" (But at least its not flat!!)

im pretty sure its 3" stock on the superduty.
