Thread: 04 cat converter.

Has anyone ever replaced the cat on and 04? My car has an p0420 code which is low cat efficiency. I allready changed my 02 sensor to see if it was the problem but it wasnt which means the cat is bad so im going to buy a new cat and change it myself, just seeing if anyone else has changed it and if its not a pain in the ass?

it'll have to be cut out and and the new on rewelded in

I know that, Im just wondering how hard it is to do without a lift and just plain old car jacks.

you can do it with jackstands, but it will be harder. unbolt the downpipe and take it somewhere where they will weld it on for you

Ok all I needed to know and I also have a welding machine in the garage so I can even do that myself. Thanks!
