Hey all!

If this is in the wrong forum, let me know so I can repost.

Bought a 14 Elantra 1.8 new. Currently has 113,000 miles. Never a single problem until recently.

Check engine cams on, had the code read and it was a P0420 and it seems the Catalytic Conv. may need to be replaced.

The couple quotes I have had are super high (1500-1800) to change the O2 and Cat out.

Anyone have any experience doing this work? Everything accessible with the right tools?

Have googled this every way I can imagine to see if a video can show me and I can’t find a thing.

Any help is appreciated!!
