Pros and Cons of Installing a Loud Mouth Axle-Back Exhaust System in a 2011-2014 Mustang GT/Boss 302/GT500

1. Pros:

a. Improved Engine Sound: The primary benefit of a Loud Mouth axle-back exhaust system is the increased exhaust flow and reduced back pressure, resulting in a more pleasant and authentic Mustang exhaust note. This is especially appealing for Mustang enthusiasts looking for a distinctive and aggressive sound.

b. Increased Performance: A free-flowing exhaust system not only enhances the sound but also offers performance benefits. Through reduced back pressure, the engine can breathe more easily, providing a slight increase in horsepower and torque.

d. Weight Savings: Axle-back exhausts typically weigh less than factory exhausts, contributing to a slight reduction in vehicle weight which can improve acceleration.

2. Cons:

a. Louder Exhaust Note: The name "Loud Mouth" suggests that this exhaust is designed to be loud, which may not be to everyone's liking. The increased volume from this exhaust could disrupt the peace and quiet, especially during early morning hours or in residential areas.

b. More Visible: The Loud Mouth axle-back exhaust's distinctive appearance could attract unwanted attention making your car stand out more than preferred.

c. Installation Complexity: The installation process can be more time-consuming and difficult compared to other exhaust upgrades due to its custom design and the need for professional expertise.

d. Cost: A higher-end performance exhaust system like Loud Mouth comes at a premium price. This investment may not be feasible for those with a limited budget.

3. Conclusion:

Installing a Loud Mouth axle-back exhaust onto a 2011-2014 Mustang GT/Boss 302/GT500 offers significant advantages such as improved engine sound, increased performance, better fuel economy, weight savings, and the thrill of an aggressive exhaust note. However, it also comes with some drawbacks like an increase in volume, visibility, installation complexity, and cost.

4. Recommendation:

If you are an enthusiast who values the sound and performance benefits of a custom exhaust, a Loud Mouth axle-back exhaust system could be the right choice for you. Be prepared for the added cost and potential unwanted attention, but enjoy the rewarding experience of unleashing the full potential of your Mustang engine's sound. If however, the increased exhaust volume and attention are unwanted, consider exploring other, quieter exhaust options to suit your preferences.
