Catalytic converter options
I was told by my mechanic that both of my converters are shot out (clogged). I was brought to this situation by check engine light on. I have a 95 LS400 with 135,000 miles. Can I purchase the converters aftermarket? Any ideas are welcomed. Thanks in advance.

First off...
What EXACTLY was the diagnosis of the CEL??
If your cats are bad they could also rattle around obscenely. Like metal jumping beans in a tin can
OEM Cats are ~$1000.00 a piece.

Without more info on the CEL I think he's trying to scam you. When cats are bad it's usually completely obvious.
Oh yeah...and if they're so clogged up they should glow red if I'm not mistaken.

Any aftermarket cat will have to be fabbed up to fit.
Plus it's very doubtful a $100 universal cat will be NEARLY as good as a $1000.00 OEM.
I'm at +156k miles on my 97 and my cats are fine.

anything from dealer is expensive. the cats only have a small trace of platinum and thats why its so high. go magnaflow high flow cats, free up some horsepower. or if u REALLLY wanna go wild...just ditch them for straight pipes.

Sorry 2 hear your cats are bad - at 228,000 miles mine on my 95 are fine.
If I had to change them I would seriously consider Magnaflow hi flow cats as long as they were guaranteed to be smog legal for Cali.

FWIW
The important point to remember here is that converters don't just plug up or die for no good reason. There is usually an underlying cause which must also be diagnosed and corrected before the problem can be eliminated. Diagnosing a plugged or fouled catalytic converter is only half the fix. Replacing a bad catalytic converter will only temporarily restore things to normal because unless the underlying problem that caused the original converter to fail is identified and fixed, the replacement converter will likely suffer the same fate.

not necessarily requiring an underlying cause, a 20year old part that is exposed to temperature extremes multiple times a day can just very well FAIL.
you check bad cats with exhaust flow, also this causes ur car to have no power at all, there is a tool that u use to drill in the pipes before and after the cats, measure the flow and when u r done u put these plugs into the holes
