Sooo my gf has a 2004 gmc envoy 4x4 with the inline 6. And we suspect that her cats are plugged. Now i still have the old cats off my 2004 1500. I was jw if it would be possable to use my old ones on her car? Thanks for the help guys.

 

Bump... ne one?

 

Possible yes, but finding someone to install them is slim, as it’s not legal to install used catalytic converters in every municipality that I know of. Of course if you install them yourself, then yes most likely you should be OK.

 

Humm never though of that? But ya i would be installing them my self if we did. Im thinking eather thay or just chopping it and throw n a stright pipe?
