massive exhaust leak just past o2, enough to cause lean code?

Would that be close enough to mess with the o2? It's where the new pacesetter pipe goes into the older pipe just before the cat. It looks like it's leaking at least halfway around the pipe. I was just under the car while it was running, looking at every gasket and feeling around them for hot air coming out, and that was the only one I could see, hear, or feel.

hmm, it's about 10 inches.

Also just found a little leak on the bottom side of the header gasket. Middle right tube. I'll try to get in there and re-torque those tomorrow.

Today I'd like to try actually enjoying my holiday.
