What code do you have?
If it is P0420, it's normal and expected because the ECU sees that the cat is missing, and you will need MazdaEdit or an AccessPORT to block the CEL from showing.
If it is a different code, it may or may not be related.

What does the Check Engine Light (CEL) Mean?: (Updated October 14th 2013)
<snip>
When the CEL lights up, there will be ONE OR MORE of these codes stored in the ECU. Some hardware failures will 'throw' more than 1 code:

Dont replace the cat. Get the CEL blocked with tuning software. You can leavr the CEL on if yur want it isn't affecting the cars performance (if anything, it's improved)

I wish people would just stop with making this seem so simple for people who obviously don't know what they're doing.
This is going to involve shelling out at least a few hundred dollars for an AP, then either learning AccessTuner or paying someone else to do it. You can tell when people make posts like these that they're most likely not going to find something like this easy and/or financially acceptable.
This forum is littered with threads like these with people spouting to "Just get an AP and mask it" with little to no actually explanation on how that's done. It's definitely not as easy as just plugging it in and the CEL goes away. I know, I have one.

No, the engine is actually safer without a cat, since it no longer stacks up heat close to the engine in front of the cat elements, and if you develop misfires, the cat can no longer clog up and damage the engine from the excess heat and pressure. I lost my first engine to a cat that clogged up.
