Well, real life and Mother Nature can be a real pain, but Worf is back together and running, again! I did splice in an 8" flex fitting on my exhaust, between the two cats. The only thing I have left to do, now, is to fab up the downpipe support for the bell housing. I had the usual fun and games bleeding the cooling system, and had to bring the yellow top back up from about 15%, but all is good, again. I also checked the A/C, since I did this job without disconnecting any of the A/C components, and it is still blowing cold! I'll post pics of the support, once I figure out how I'm going to do it!

Ouch . Looks like it's time to make that brace I put on the back burner and modify the stock cross-over to replace the ORS when it does crack.

What's your plan with the stock x-over?

Modify it like Jason4x4 did to dump on the driver side, but machine a new collector flange or modify the stock one so it can bolt to a support on the bellhousing like it did on the passenger side. I think the cross-over really needs a mount point at the flange just like the stock config to eliminate or minimize any twisting forces.

mine seems to be working fine for over a year now no problems and instead of wrapping it is now ceramic coated so i can see immediately if it where to crack. btw just so all of you know if you have a 3 inch body lift all you have to do is drop the transmission crossmember and lower the trans about 4 inches and you can slide the crossover out the drivers side wheel well

One big plus with the older cross-over design is it that it is made of two separate pipes and there is no welded junction to fail.

I'm concerned that mine might have cracked due to temperature extremes. I haven't really located the leak but it's definitely on the drivers side. It could be related to a twist/torque issue too. cadman you got yours out by lowering the transmission right? Was that the ORS crossover?

Yes, I was able to remove and re-install my ORS cross-over from the driver side by lowering the rear end of the transmission. I just put my tranny jack under the crossmember and unbolted it rather than remove the cross member and move the tranny itself. I have a 1" bl and the spacer I currently have on the cross member lifts the tranny 1" over the stock height, so that probably negates the bl lift somewhat.

So mine cracked at the collector but I think that was because I ground the weld down a little too thin. I don't know what broke the weld though. It could have been torque or cold snow getting on the hot pipe. Either way it was on the outside area so I was able to weld it without removing it or taking the wheel off. Took about 5 minutes

hey syber take a look at my post on the bottom of Dales thread

here http://www.yotatech.com/f160/3-4-swa...5/index29.html

Dale had a crack as well. seems the welded joint is prone to failure. especially when wrapped, with no flex coupling before or near the cat, and no tranny/exhuast mount support.
