The ND Miata is a beloved sports car known for its agility and driving pleasure. However, many enthusiasts seek to enhance both the sound and performance of their vehicles. One effective modification is the installation of a catted downpipe. This article will guide you through the process of installing a catted downpipe on your ND Miata, providing you with improved sound and power for around $500.
What is a Catted Downpipe?
A catted downpipe replaces the factory downpipe and includes a catalytic converter. This modification allows for better exhaust flow while maintaining emissions compliance. The benefits of installing a catted downpipe on your ND Miata include:
- Increased horsepower and torque
- Enhanced exhaust sound
- Improved throttle response
- Better overall performance
Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- Socket set (including extensions)
- Torque wrench
- Jack and jack stands
- Safety goggles and gloves
- Catted downpipe (specific to ND Miata)
- New gaskets and bolts (if necessary)
- Exhaust hanger removal tool (optional)
Step-by-Step Installation Guide
Step 1: Prepare Your Vehicle
Start by parking your ND Miata on a flat surface and engaging the parking brake. Use a jack to lift the front of the car and secure it with jack stands. This will provide you with ample space to work underneath the vehicle.
Step 2: Remove the Factory Downpipe
Locate the factory downpipe, which is connected to the exhaust manifold and the rest of the exhaust system. Using your socket set, remove the bolts securing the downpipe to the exhaust manifold. You may need to disconnect the exhaust hangers as well. Carefully lower the downpipe and remove it from the vehicle.
Step 3: Install the Catted Downpipe
Position the new catted downpipe in place, ensuring that it aligns correctly with the exhaust manifold and the rest of the exhaust system. If your downpipe came with new gaskets and bolts, use them for a secure fit. Tighten the bolts to the manufacturer’s specifications using a torque wrench.
Step 4: Reattach Exhaust Hangers
Reattach any exhaust hangers that were removed during the process. Make sure everything is aligned properly and secure. If you have an exhaust hanger removal tool, it can make this step easier.
Step 5: Check for Leaks
Before lowering your vehicle, it’s essential to check for any exhaust leaks. Start the engine and listen for any unusual sounds or hissing. If you detect a leak, turn off the engine and inspect the connections to ensure everything is tight and properly sealed.
Step 6: Lower the Vehicle and Test Drive
Once you’re confident that there are no leaks, carefully lower the vehicle back to the ground. Take your ND Miata for a test drive to experience the improved sound and performance of your new catted downpipe. Pay attention to the throttle response and any changes in acceleration.
Benefits of Installing a Catted Downpipe
Installing a catted downpipe on your ND Miata offers several advantages that can enhance your driving experience:
- Sound Improvement: The catted downpipe provides a more aggressive exhaust note, making your Miata sound sportier.
- Power Gains: By improving exhaust flow, you can expect noticeable increases in horsepower and torque.
- Throttle Response: The modification can lead to a more responsive throttle, giving you a more engaging driving experience.
- Cost-Effective Upgrade: At around $500, this upgrade is relatively affordable compared to other performance modifications.
Conclusion
Installing a catted downpipe on your ND Miata is a straightforward process that can significantly enhance both sound and performance. With the right tools and a bit of patience, you can complete this modification for around $500. Enjoy the new sound and power of your Miata as you hit the road!
