Question on these, anyone know if one of these replaces both to the exsiting ones on the OEM pipe?

You'd be surprised I think. I'd challenge you to find OEM Cats for my truck for under $1200 a piece. (those above are $600 a piece) I had a quote before I started to do this myself, and they would have got a universal cat and welded it in. But now that I have it apart I know both cats are junk not just the one he was going to do. My thought process was - I'm not afraid to do the work myself, and maybe with the money saved I could do a few extra things (like headers and a better sounding muffler), get a direct fit. I didn't want to get into welding and stuff. But maybe I can see if I can have a shop just do that for me. my stock pipes are in pretty decent condition.
Got the exhaust manifolds off today. I had about 3 screws that broke off at the manifold top and about 3 others that the nut came off and the screw was left in tack.

As for the exhaust manifolds, a mechanic I know just did head gaskets on a 5.4 and also had problems with broken manifold studs as he removed the heads. We have lots of salt use on the roads here in the winter. Corrosion is just a fact.

Winter does suck, but that's one reason I got my truck. Starting to see the typical bottom of the doors rust issues. Wondering if I should get it cleaned up, or just let it go.
I guess I'm lucky I can take this slow. I still have a lot to think about.

Item Details
You would need one on each bank, and you would need to replace the front pre-cat with a piece of pipe. Also just some advise, stay well away from Magnaflow. They do not make good cats. In fact, partly because of their low quality and partly because they were selling stuff under the table, they just lost their largest distributor network, Allied Exhaust.

If I were you, I would leave the stock converter y-pipe in place and just cut the cats out and weld new ones in. A muffler shop will be needed for this, but I bet you will spend a lot less than buying the y-pipe. If the shop is any good, you will end up with better results too.

Best to take the truck to them for the cats. Put the headers on. Cut the old cat out. Install the pipes to the headers. Slip the new cats on and install the new y pipe and muffler and rest of system. Then drive down and have them weld it up. It will leak some but not enough to hurt anything other than some extra noise. New cat should slip over or inside pipe. Should not be a but joint.

I found another source for the JBA headers. Anyone ever use SuperExhaust.com?
SuperExhaust.com - Shopping Cart
it's a savings of $50 over Summit for the same product.
I think I'm ready to order these at least. Like to hear if anyone knows of them first.
I'm thinking about the individual BearRiver high flow cat replacement option. I'm worried it's going to add a level of frustration for me. Had to cut off the EGR tube last night to get it off the manifold and that was about as much hack saw cutting I could handle. I don't have serious cutting tools. I suppose I could sit there with my dremel and eventully cut the pipes. Or I just bring it into a shop and have them do it. I really wanted to do this project myself. But, I do think it would accomplish what I want to accomplish.

Go buy you a saws all. Good excuse to buy one. Harbor Freight has them cheap. Just get you a good blade from Lowes or somewhere (the harbor freight ones are junk).

Ok, I will consider my options. I'll have to find some time to call some local shops and see how this will work with them.
Ordered the JBA Headers today. I'm in the process of ordering a new EGR tube (ended up cutting it off the manifold to get it off), and my O2 sensors. Looking at partsgeek as suggested. Will be a better deal to get the Motorcraft ones from them. Didn't know that Bosch made those too, so these should be good. I read in some other threads that you really don't need to get the rear o2 sensors replace until they fail. So for now I may just skip those. Sound ok?
