Ford Mustang GT Offers New Quiet Mode Exhaust

Ford Mustang GT Offers New Quiet Mode Exhaust

After a brief conversation with his fellow engineers, they came up with the concept for the quiet exhaust mode. All in, a 2018 Ford Mustang GT with the active exhaust system bears a starting price of $38,890. On an otherwise peaceful morning in his suburban Detroit neighborhood, Von Foerster had just backed a Shelby GT350 Mustang out of the driveway (Shelby GT350 is equipped with a two-mode active exhaust), and as the Voodoo V8 engine cracked to life, an annoyed neighbor dialed the police.

Ford Mustang 2018 will now come with "Quiet Mode" which allows you to reduce the noise of the car's exhaust.

It's part of a new active valve performance exhaust system, and owners will be able to activate the mode on the go or choose a programmable Quiet Start function to make sure the vehicle doesn't disturb those around it upon startup. That's good for the track and strip, but not great when you give your neighbor a 6 a.m. wakeup call day, after day, after day. Von Foerster was gone before the law arrived and didn't get a ticket - but he did get an idea for the new Mustang. However, your neighbours might not like it as much as you do, especially if you usually leave the house early in the morning.

According to a recent poll by digital media firm, loud engine revving ranks among the most annoying noises neighbors make.

To access this feature, drivers toggle through a menu in the instrument cluster to select when they want to cater to the quiet whims of their nosey neighbors.

Matt Flis, Ford exhaust development engineer, said when sounds get to about 70 decibels that is typically the level that starts to bother people. The system uses an active valve performance exhaust system that closes valves to restrict the amount of noise made by the vehicle. According to Ford, Quiet Start, also known as "Good Neighbor Mode", is essentially a timer you can program to automatically put the active exhaust into its quietest mode during certain hours, even if you parked it in wide-open track mode. The Quiet mode lowers the 5.0-litre V8's roar to 72 decibels, a drop of about 10 dB compared to Normal mode.
