Well...apparently I'm 7000 miles outside my warranty, and was told this morning that my Code 420 means the catalytic converter is done...NOT a happy morning...anyone else got this horror story...or words of encouragement? Sheeeeeeeit.

 

What kind of truck do you have? I believe the convert has it's own warranty.

 

2003 H2...8 year or 80,000 miles...or so I'm told.

 

Do a cross reference and see what other vehicles use the same catalytic converter and then visit your local wrecking yard.

 

I have a buddy who ha an 03 and ignored that error now he is replacing his engine.

 

Get stainless high flow CATs to replace the stock. They are relatively cheap, and any muffler shop can throw them on PDQ.

Good luck.

 

no emmisions testing.. No cat.. Gut that sucker...

I mean, what the hell right? you're already part of global warming.. lol

 

make that thing sound like a true beast

great idea

 

Bronx, what did you wind up doing?

 

FYI, just in case you want oem replacement.

You might want to check and see if your O2 sensor is not burnt out because that can give you a bad code if there is one after the cat.
