Yea i would look at ebay honestly. That's where i got my tips. Pretty good quality too mostly from china.
Here is the ones i had on before but since mine is a 23 gt2 that has oval exits i ended up changing it to something else thay fit far better yet didnt rub against the exit as i tried 5 inch outlets and they were touching the exits. Would cause vibration, rubbing or damage the bumper.
Since you have a 2020 yours is not the oval exits. You need round ones.
Round tips:
You can also go for these without the blue colored tips, just chrome:
Just make sure you choose correct inlet size 2.5" and then i assume 4 inch would be ok or maybe 3.5. I would measure the exits on your car.
This is what I am running on my car now with borla active catback (2.25 inlet 4.5 outlet). Looks great and they look like good quality too:

At least we have good options on ebay. Just takes a while to get the darn tips. But yeah mine look great and they help with drone and make a difference in sound as well so it doesn't bounce back in the rear bumper. Attached picture of them.
Hopefully that helps.
