Leaks need to be welded

Get that fixed, run the BG 44K, and get a new O2 sensor (as has been mentioned several times)

Finally Passed Smog.

Went over both welds on the cat and took it in for a test.

Nox at 15mph was 307 max is 517
Nox at 25mph was 27. Max is 539

Lesson learned that I have to double check work that others do to my jeep.

Thanks for all the repair suggestions along the way. Time to get out and take her wheeling.
