Enhancing Performance and Sound with Miata Aftermarket Exhaust Systems

The Mazda Miata, known for its sleek design and exhilarating driving experience, can be taken to new heights with the addition of an aftermarket exhaust system. These systems not only enhance performance but also offer a distinct exhaust note that sets your Miata apart. In this article, we will explore the benefits of upgrading to an aftermarket exhaust system, factors to consider when choosing one, the different types available, installation tips, and maintenance guidelines.

Benefits of Upgrading to an Aftermarket Exhaust System

Upgrading to an aftermarket exhaust system brings several advantages to your Mazda Miata:

  • Increased Performance: Aftermarket exhaust systems are designed for improved airflow, reducing backpressure, and increasing horsepower and torque. This leads to enhanced acceleration and overall performance.
  • Distinct Sound: One of the most exciting aspects of an aftermarket exhaust is the sound it produces. You can achieve a deeper, more aggressive tone that adds excitement to your driving experience.
  • Customization: Aftermarket exhaust systems offer customization options, allowing you to choose the level of performance, sound, and appearance that suits your preferences.

Factors to Consider When Choosing an Aftermarket Exhaust System

Before investing in an aftermarket exhaust system, consider the following factors:

1. Performance Goals: Determine whether you want to prioritize horsepower gains, torque improvement, or both. Different exhaust systems are designed to cater to specific performance goals.

2. Material and Build Quality: Quality materials like stainless steel ensure longevity and resistance to corrosion. A well-constructed exhaust system can last longer and withstand various driving conditions.

3. Sound Preferences: Decide on the level of sound you desire. Some systems offer a mild enhancement, while others provide a more aggressive and attention-grabbing exhaust note.

Different Types of Aftermarket Exhaust Systems

Aftermarket exhaust systems come in various configurations. Here are the most common types:

1. Axle-Back Exhausts: This type replaces the exhaust components from the rear axle to the exhaust tips. It offers a sound upgrade and minor performance gains while keeping the stock catalytic converter and resonator.

2. Cat-Back Exhausts: By replacing components from the catalytic converter with the exhaust tips, cat-back systems provide more significant performance improvements and a louder exhaust note. They maintain emissions compliance.

3. Header-Back Exhausts: These systems replace the entire exhaust system, starting from the exhaust manifold. They provide the most extensive performance gains and a complete change in exhaust sound.

Installation and Professional Help

While some enthusiasts opt for a DIY installation, it’s advisable to seek professional help. Experienced mechanics can ensure proper fitment and alignment, preventing leaks and potential issues.

Maintaining an Aftermarket Exhaust System

To keep your aftermarket exhaust system in optimal condition:

  • Regular Inspections: Routinely inspect the exhaust system for any signs of damage, loose components, or leaks.
  • Cleaning: Clean the exhaust tips regularly to prevent carbon buildup and maintain a polished appearance.
  • Check for Rust: If your exhaust system is not made of stainless steel, monitor it for signs of rust and address the issue promptly.


Upgrading to an aftermarket exhaust system is an exciting way to enhance the performance and auditory experience of your Mazda Miata. With considerations such as performance goals, material quality, and sound preferences, you can select the perfect exhaust system for your needs. Remember to prioritize professional installation and regular maintenance to enjoy the benefits of your new exhaust for years to come.
