Preparation
Before starting the installation, ensure you have all the necessary tools and materials. Make sure to work in a well-ventilated area and wear safety glasses and gloves for protection.
Step 1: Lifting the Car
Use a jack to lift the rear of the car and securely place it on jack stands. Ensure the car is stable before proceeding to the next steps.
Step 2: Removing the Stock Exhaust
Locate the stock exhaust system and begin by loosening the clamps and bolts connecting it to the catalytic converter and the exhaust tips. Carefully remove the exhaust hangers using a pry bar if necessary.
Step 3: Installing the Borla Exhaust
Position the Borla exhaust system in place, starting with the connection to the catalytic converter. Align the exhaust tips with the bumper cutouts and ensure everything fits snugly.
Step 4: Securing the Exhaust
Once everything is aligned, use the clamps and bolts to secure the exhaust system. Make sure to tighten them to the manufacturer’s specifications using a torque wrench.
Step 5: Final Checks
Before lowering the car, double-check all connections and ensure the exhaust hangers are in place. Make sure there are no leaks in the system.
Sound Tests
After installation, it’s time to test the sound of your new Borla exhaust. Start your car and let it idle for a minute. Listen for any unusual noises that might indicate a poor installation.
Rev Test
Perform a rev test by gently pressing the accelerator while stationary. Note the changes in sound compared to the stock exhaust. The Borla exhaust should produce a deeper and more aggressive tone.
Drive Test
Take the car for a short drive to experience the sound under load. Pay attention to how the exhaust note changes when accelerating and decelerating.
Conclusion
Installing a Borla exhaust on your M2 Competition is a rewarding project that can enhance both performance and sound. By following this guide, you should be able to complete the installation successfully and enjoy the new exhaust note.
