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:
Material: Stainless Steel and Carbon Fiber. This is exhaust tip only, would not make sound or any smog problems. We have our own warehouses in the United States, the United Kingdom, and Germany, and we have more products in China.

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.
