Quick way to gut a catalytic cadalac converter  

I cut a box into both my cats and beat all the honeycomb out with a hammer then welded it back on

When I gutted my 2010 Honda coupe 3.5 V6 I left $600 to thousand dollars worth of precious metals on the ground didn’t realize I could’ve sold it as is too a company not far from me it had started to rain 🌧️ hard when my cousin pulled up and told me about it lol 😂

Mine doesn't have sensors on it. Lucky me. I'm gutting it today. It's off the car already

I used an inch and 1/8 long paddle bit on my drill works great

That a vw downpipe?

I want to do this to my corolla but don’t want an check engine light? How can I avoid that ?

Air hammer another option

What’s that coming out
