It's because you no longer have a cat.
A cat delete is just a test pipe.

After doing a bit of research I found the solution 18mm spark plug non fowler and a 1/2 drill bit thanks again 6thgen!

or u might have not installed an o2 sensor
O2 sensor extension.
I used a street elbow (3/8", iirc) than a sensor extention, then the sensor. I had to re-tap the extension to fit NPT, but the pipe threaded right in!
3/8"npt is like 5/8"-14tpi which is DAMN close to metric! Ours is like 18mmx1.5.
No check engine light, and adding the elbow means we have no clearance issues.
