How do I minimize all noise except the exhaust?

[Artizan]

I’m wondering which panels would you apply sound deadening onto to accomplish this?

 

I’m guessing all the doors, the front everywhere. Top of the trunk.

What about rear seats and trunk floor?

 

Also, is there a way to apply sound deadening to the firewall without disassembling half a car?
