exhaust problem on 2001 4.0 sohc xlt

[pjb153]

My exhaust broke right behind what appears to be cat or pre heater. On the right side where the manifold pipe comes down (about as far back as where the passenger door is). There is a connection which is bolted. The end of the chamber has come apart from the connection. It appears oval and has come apart from the flange.

I have not crawled underneath yet. Does anyone have a diagram or detailed photo so I can be sure of the part I am talking about?

If it is stainless, I might either find someone that welds stainless, or bypass with a pipe to the cat.

It is sort of where this person replaced on this 4.0 Ranger photo. http://ford40.com/graphics/collectortocat2.jpg

Link to entire project he did. http://ford40.com/exhaust.shtml

I am just wondering what this chamber is and if it can be removed or welded.

thanks

Well after more information searching, this is actually the dual cats on the 4.0 explorer. The cat ovals directly into the flange and this is where it popped out. Does anyone know if there is a replacement donut gasket for this?

here is a picture of it where it popped.

I had something similar happen to mine but mine just leaked really bad.
Do your cats hang down really low, like below the crossmember?
Is that normal.
I just welded mine back together.

I don't think they hang low.. it is just the angle of the photo. I was told they are stainless steel and would need to be specially welded.

How did you weld yours?

I was just seeing how your cats were because mine hang down really low,
I think thats how I keep getting leaks because I hit them on stuff.
I took it to a friends shop and had him help me weld it im not really sure I dont know much about it.
