23: Upgraded Exhaust
It’s been a long time since automakers actually added an aftermarket exhaust from the factory. But Ford is going this route with the Mustang in order to better compete with Chevy. The NitroPlate quad-tip performance exhaust has a deep growl to it. For a factory exhaust, this is actually a welcome addition. If you’ve ever heard a factory 5.0 exhaust setup, you’ll be pretty pleased with it.

Obviously, most owners are going to rip the factory exhaust off as soon as they get to the muffler shop. But even straight from the factory, the Mach-1 is going to be a stellar performance car with excellent sound.
