The NB Miata is a beloved sports car that offers a thrilling driving experience. One popular modification among enthusiasts is the installation of a Racing Beat cat-back exhaust system. This guide will walk you through the step-by-step process of installing this performance upgrade.
Tools and Materials Needed
- Racing Beat Cat-Back Exhaust System
- Socket set
- Wrench set
- Jack and jack stands
- Safety glasses
- Gloves
- Lubricant (WD-40 or similar)
Preparation
Before starting the installation, ensure that you have all the necessary tools and materials. It’s also important to work in a well-ventilated area and wear safety gear to protect yourself during the process.
Step 1: Lift the Vehicle
Using a jack, lift the rear of the vehicle and secure it with jack stands. Ensure the car is stable before proceeding with the installation.
Step 2: Remove the Stock Exhaust
Locate the stock exhaust system under the vehicle. Start by removing the bolts that connect the exhaust to the catalytic converter using a socket wrench. Apply lubricant to the bolts if they are rusted or difficult to remove.
Next, disconnect the hangers that support the exhaust system. You may need to use a pry bar or a similar tool to help remove the hangers from their mounting points.
Once all connections are detached, carefully remove the stock exhaust from the vehicle. Be cautious as the exhaust can be heavy and awkward to handle.
Step 3: Prepare the Racing Beat Exhaust
Unbox the Racing Beat cat-back exhaust system and lay out all components. Familiarize yourself with the parts included in the kit, which typically consists of the muffler, piping, and necessary hardware.
Step 4: Install the New Exhaust System
Begin by positioning the new exhaust system under the vehicle. Start with the mid-pipe and attach it to the catalytic converter using the provided hardware. Make sure to align the pipes correctly.
Next, attach the muffler to the mid-pipe. Ensure that the exhaust hangs at the correct height and is not touching any other parts of the vehicle.
Secure all connections with the provided bolts and clamps. Tighten them using a socket wrench, but be careful not to overtighten and damage the components.
Step 5: Reinstall Exhaust Hangers
Reattach the exhaust hangers to their original mounting points. Ensure that the exhaust is properly supported and that there is no excessive movement.
Step 6: Check for Leaks
Before lowering the vehicle, it’s important to check for any exhaust leaks. Start the engine and let it run for a few minutes while inspecting the connections. Listen for any unusual sounds and look for any signs of exhaust fumes escaping.
Step 7: Lower the Vehicle
Once you have confirmed that there are no leaks, carefully lower the vehicle back to the ground using the jack. Remove the jack stands and ensure everything is secure.
Step 8: Final Inspection
Take a moment to do a final inspection of the installation. Make sure all bolts are tightened, and the exhaust system is aligned properly. Check the clearance to ensure it does not touch the undercarriage of the car during operation.
Conclusion
Congratulations! You have successfully installed a Racing Beat cat-back exhaust on your NB Miata. Enjoy the enhanced performance and sound that comes with this modification. Always remember to consult your vehicle’s manual for any specific instructions or recommendations regarding modifications.
