Default Cat converter question.

I was changing the oil on the lift the other day and looked for the rattle under the car. I found it, it was the cat converter, must be all busted up inside. Do the new converters come with an expanded end on each side? My converter on the front looks like it a press fit. The only way i see getting it off is by cutting it off. Please let me know your thoughts.

Thank you,
Sellncars

It'* actually press-crimped. But the result is the same. Cut away.

Thanks for the heads up guy'*, i appreciate it. Sawzall'* all warmed up and ready to start cutting. Is there much of a difference between the high flow and the stock converter?

Thanks again,
Sellncars

About 10% in flow. Enough to ALMOST feel, but makes a performance diff when done with the muffler. Worth it.

Noise? Makes a difference on the 92 and 93 that never saw a factory resonator.
