Truck failed inspection because cat too close to floor. Cheap fix?

Has anyone thought about a heat shield?

Not even enough room for a heat shield. There needs to be space between the shield and the CAT, and the shield and the floor.

Thats the first thing that went through my mind, but I have no idea if that would pass inspection or not. The OP needs to get with the inspection shop, and ask for recommendations, IMO.

My mechanic doesn't do any welding. I have the ability to do the required cutting and welding, just not sure where exactly to cut to make this fit nicely

Wrap it in 3M interam material and stick a layer to the under side of the floor as a double shield:

The rest of the exhaust is sitting properly

Respectfully, no it isn't. If the exhaust was where it belonged, the cat wouldn't be that close to the floor. What's been done pre-cat? At very least you need to lower the rear of the pipe, probably achieve that with longer hangers, and that in turn may create enough clearance to put a heat shield on top of the cat. Find you a stock one to crawl under and get some measurements.

In looking at it, isn't the cat upside down? The heat shield on it is on the bottom plus, the O2 sensor shouldn't be pointing straight down maybe?

That's what I thought.

I thought some cats had heat shields on the bottom to keep from igniting grass or whatever, but maybe y'all are right and it's on upside down.

The way it sits now, a small rock will take out the O2 sensor and then it'll start the grass on fire

Fair....
