I've searched and searched and could not come up with the factory torque specs on the two downpipe bolts that connect the downpipe to the 02 housing.

Thanks all!

Here is the service manual Spec sheet. Let me know if you have problems downloading it. Remember the stock pipe has springs so it won't come loose and for impact so use thead lock on the bolts and seel it up on the rim as well.

Is there a thread lock available for high temperature applications? Usually threadlock compounds such as Locktite red are basically plastic and are "deactivated" using heat.

Also, if anyone is using an aftermarket downpipe with a gasketless or donutless flat DP flange, you've got to be careful not to over torque the two bolts. Using the factory O2 housing it's possible to overtorque the two bolts which will bend the ears of the flange and cause it to warp and leak. It's easy to do if you're attempting to tighten the bolts to take care of a leak at that joint. Tightening will work up until the point where you ned the flange, after that a leak will just get worse the tighter your bolts get. BTDT...

Yes they do make high temp thread lock. I believe it is a blue color I picked some up from a local parts dealer when I did my exhaust sometime ago then I used it again on my cam gear bolts when I installed my cams. It specifically says for high heat applications, people have used high heat silicone on the threads as well and it works just fine also. This I would trust on exhaust componets only.
