Stock has a good sound and I think GMPP sounds even better.
By the time you find a "quality" recording you will have had plenty of time to go test drive a real STS and hear it first hand. The stock sound is mostly just engine and intake noise. When you change the exhaust out to something else is about the only time you'll actually hear it in the car well.
