My 84 XJ was running bad and I found the stuff in the cat was blocking the flow. I took the cat off and removed all the inerts, put it back on and it still passed with fling colors. Years ago I was replacing a muffler on my BMW and found it had nothing in the cat and it passed just fine. That's why I tried it on the XJ.
