The Mazda Miata is a beloved sports car known for its lightweight design and agile handling. One popular modification among enthusiasts is the installation of a cat-back exhaust system, which can enhance performance and sound. In this article, we will guide you through the process of installing a Perrin cat-back exhaust on your Mazda Miata, highlighting the steps involved and the potential power gains you can expect.
What is a Cat-Back Exhaust?
A cat-back exhaust system includes all the components from the catalytic converter to the exhaust tip. Upgrading to a performance cat-back exhaust can improve exhaust flow, reduce back pressure, and enhance the sound of your vehicle. The Perrin cat-back exhaust is designed specifically for the Mazda Miata, offering a perfect fit and optimal performance.
Benefits of Installing a Perrin Cat-Back Exhaust
- Increased Horsepower: Expect a noticeable increase in horsepower due to improved exhaust flow.
- Enhanced Sound: A deeper, more aggressive exhaust note enhances the driving experience.
- Weight Reduction: Aftermarket exhaust systems are often lighter than stock components.
- Improved Aesthetics: The polished tips and design can enhance the overall look of your Miata.
Tools and Materials Needed
- Jack and jack stands
- Socket set
- Wrench set

Step-by-Step Installation Guide
Step 1: Prepare Your Vehicle
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Use the jack to lift the rear of the car and secure it with jack stands for safety.
Step 2: Remove the Stock Exhaust
Start by applying penetrating oil to the exhaust hangers and bolts to make removal easier. Use your socket set to unbolt the exhaust from the catalytic converter and any mounting points. Carefully remove the stock exhaust system from the hangers and set it aside.
Step 3: Install the Perrin Cat-Back Exhaust
Begin by positioning the Perrin cat-back exhaust in place. Align it with the mounting points and attach the exhaust to the catalytic converter using the provided hardware. Make sure to tighten the bolts securely but avoid over-tightening.
Step 4: Secure the Exhaust System
Once the exhaust is attached to the catalytic converter, slide the exhaust hangers into place. Ensure that the exhaust is properly aligned and sits securely without any contact with the chassis or suspension components.
Step 5: Double-Check Everything
Before lowering the vehicle, double-check all connections and ensure that everything is tightly secured. Look for any signs of misalignment or interference that could cause issues during operation.
Step 6: Lower the Vehicle and Test
Carefully remove the jack stands and lower the vehicle. Start the engine and listen for any unusual noises. Take the car for a short drive to test the new exhaust system and enjoy the enhanced sound and performance.
Expected Power Gains
After installing the Perrin cat-back exhaust, many Miata owners report an increase in horsepower ranging from 5 to 15 horsepower, depending on the model year and other modifications. This improvement is due to the increased exhaust flow and reduced back pressure, allowing the engine to breathe more freely.
Conclusion
Installing a Perrin cat-back exhaust on your Mazda Miata is a rewarding project that can enhance both performance and sound. By following this step-by-step guide, you can successfully upgrade your exhaust system and enjoy the benefits it brings. Remember to always work safely and consult a professional if you are uncertain about any steps in the installation process.
