Catalytic Converter Help!

1845 Views 1 Reply 2 Participants Last post by  kscoyote
I just realized that one of my catalytic converters is damaged in my 1996 mustang...I was wondering how long I can drive with it without doing serious damage to my car (if any)? Second, I have a friend back home who said he could clean out both catalytic converter casings so essentially it would be 2 catalytic converters with just the outer casings (no inner parts)...my question is would this hurt/help horsepower? Would it make my car sound better/worse keeping in mind I have dual 40 series flowmasters? Thanks for the help!

If it plugs, it could cause some power losses and a CEL,

If you hollow them out, it's basically zero-sum. Though you may get a CEL.

It will be louder if they're hollowed out.
