I guess I am wrong then I don't recall mine getting that high but maybe they did get a lot higher and then cooled down to 800 at idle, I know it is posted on here somewhere but the search function is not exactly spectacular

So my converters are running 300°F when I used a IR laser temp gun. And then my OBD PID Bank for it says 1200°F and doesn’t really change. (I’ve only gotten up to 25mph looking at the temp tho) my buddy says 1200 is normal? Need @swathdiver to verify.

when I looked back my post's in 2019 I was getting over 1200deg, and getting poor mpg and one failed shortly after trying to figure out why i was getting significantly less gas mileage for no apparent reason

I don’t think I’m getting bad gas mpg. I get like 10-11

My buddy who was a service tech is telling me 1200° is normal for light trucks. And suv

Idling they can get up to or cool down to 700-800 degrees. I've hit near 1600 accelerating onto the highway. Then they cool down again. Don't remember the specific numbers but it's on here somewhere as we've talked about this a few times over the years. These are virtual numbers calculated by the computer.

Is there easy ways to check for clogged cat?

check temps or backpressure test, sometimes people pull the 02 sensor out and stick a camera in there

Ok and the cheapest way? What’s back flow test
