How do I quiet down a 2015 Scion tC Exhaust/Valve Train?

Hi, anyone else notice that the 2014/2015 OEM Exhaust makes an obnoxious trebly sorta sound every time you hit the gas. How do I quiet that down?

I've been reading online for like 3 hours now and will an exhaust silencer work? Valve train cover? I don't get it. Does the sound actually come from the back of the vehicle where the exhaust lets out or from the front of the vehicle near the engine?

Please help. Just got the car a couple days ago and noise is driving me crazy.

Hi I have a 2015 Scion tC 16k miles, when I turn on the AC, car is in drive,
There's a rattle underneath the drivers side door. Took it to the dealer and they say it's
Normal from the muffler pipes, they also said don't worry tour car is
Still under warranty. What kind of answer is that? Took it to a muffler shop
Wanted to charge $250 for a bracket that goes between the catalytic converter
And muffler pipes.

Does anyone know what this noise is?
