It should be compatible, they're the same shape so it would just be a matter of finding the part number and ordering it. I believe the part number is 86612G3010 - can be seen here - 2018-2020 Hyundai Elantra GT Cover-Rear Bumper Lower 86612-G3010 | Hyundai Access Parts

That's what I was thinking too. Thanks for the reply

I'm not sure if the rear of the car is suitable for a double exhaust though, I believe there is a plastic contraption on the left side of the rear bumper where the other exhaust tip would go. Maybe go look under the back of your car and post a picture.
