New to Mustangs and I have a question

I recently purchased a 2002 Mustang GT 4.6 the car is in really good condition with all the service records. My question is the service engine light is on the persons I purchased the car from says it is because he removed the cats and has an x pipe off road exhaust on it making the o2 sensors read hotter than normal causing the light to come on.

The car runs great no leaks or other issues, is what the guy stated true or should I do some digging into other causes?

Thanks again for the help.

Sounds true to me as long as everything is running good. You can get mil eliminaters to get rid of the cel or a handheld tuner to shut the rear 02s off.

If wanting help with a check engine light it's best to have the DTC codes read and posted. Remember there are 1,000's of them and they each have a story to tell.

2000 GT coupe (Craigslist project. Fixed. Now my DD). Windsor to Romeo swap.

What he is saying is that the car doesn't have any catalytic converters and that's why there is a light. I won't hurt anything but it won't pass emissions testing if you are required to.
Get a code reader, it's a good addition to the tool box. Here's one for under $20. https://www.amazon.com/gp/aw/d/B01I8...wbL&ref=plSrch

Thanks no emission tests required in Idaho so I am good there. I am looking into the mil eliminators to take care of the light issue.
