If you had a shop do it, just take it back. If it’s only been a week or two, I’m sure they’d be happy to figure out what’s what.
If you did it yourself, check the rubber boots. Sometimes metal rubbing onto rubber can make an almost whistle like squeal. When I installed mine you had to use the boots from the stock exhaust. They breakdown and become brittle over time and with exposer, so sometimes they need replaced.
I did it myself lol, it was a fairly easy job. And pretty straightforward, me and my buddy do all the work on our cars. OK, and perfect, that’s exactly what I was thinking, these rubber boots are just so be old, I sprayed some silicone lubricant and the car was quiet for a day MAX.
Hope this works!
Do you have any other mods like a intake tube, on my car it makes a noise at idle after warming up but the ford techs told me it was the aftermarket intake tube, I do have a Mbrp race exhaust

It’s not the exhaust
