Help Again! Clogged Exhaust

While driving to my favorite lunch establishment, My Jeep grandually loses power as a strange hissing sound increasing. It was determined to be a clogged Cat. Converter. I had the converter and the muffler replaced and it ran great. About three miles down the road the whole thing starts up again. Did I really clog the new converter that fast? What could cause this? I am running a '77 CJ7 with a 304 and headers. Thank you for your help.

Re: Help Again! Clogged Exhaust

No the intake is fine. It is the exhaust. It is definitly at the Cat. Converter. Exhaust is blowing out a high pressue from a crack in the headers and there is nothing coming out of the tail pipe. To get it on the lift the muffler guy just cut exhaust pipe before the Converter and it ran fine. Could oil be getting in the headers? If so how? This is seeming more and more like a bad thing.

Re: Help Again! Clogged Exhaust

Rich exhaust mixture will clog them.Unless it was defective to begin with.
Or internal damage during shipping ?
