Preparation Steps

Before beginning the installation, ensure that your vehicle is parked on a flat surface and the engine is cool. Gather all necessary tools and materials to avoid interruptions during the process.

1. Secure the Vehicle

Use a jack to lift the rear of the vehicle and place it securely on jack stands. Ensure the vehicle is stable before proceeding with the installation.

2. Apply Penetrating Oil

Spray penetrating oil on the exhaust bolts and hangers. This will help loosen any rusted or seized components, making removal easier.

Removing the Stock Exhaust

To install the Apexi N1 Exhaust, you must first remove the stock exhaust system. Follow these steps carefully.

1. Disconnect the Exhaust from the Turbo

Locate the flange connecting the stock exhaust to the turbo. Use a 14mm socket to remove the bolts and disconnect the exhaust from the turbo.

2. Remove the Mid-Pipe

Next, locate the mid-pipe section of the stock exhaust. Remove any bolts or clamps securing it to the rear section of the exhaust. Use the appropriate socket to detach it completely.

3. Take Off the Rear Section

Finally, remove the rear section of the stock exhaust. This may require loosening additional bolts on the hangers. Carefully slide the exhaust out from under the vehicle.

Installing the Apexi N1 Exhaust

With the stock exhaust removed, it’s time to install the Apexi N1 Exhaust system. Follow these steps for a successful installation.

1. Position the Rear Section

Start by positioning the rear section of the Apexi N1 Exhaust under the vehicle. Align it with the existing hangers and ensure it fits snugly.

2. Attach the Mid-Pipe

Next, attach the mid-pipe to the rear section of the exhaust. Use the provided clamps and ensure a tight fit. Tighten the bolts securely.

3. Connect to the Turbo

Now, connect the exhaust to the turbo. Align the flange and use the bolts removed earlier to secure it in place. Make sure it is tightly fastened.

4. Secure the Hangers

Ensure all hangers are properly secured. Adjust the exhaust to ensure it does not touch any other components of the vehicle. This will prevent rattling and ensure optimal performance.

Final Steps

Once the installation is complete, perform the following final checks.

1. Double-Check Connections

Go through each connection and ensure everything is tightened to the manufacturer’s specifications. Use a torque wrench for accuracy.

2. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground. Ensure there are no tools left under the car.

Start the engine and listen for any unusual sounds. Check for exhaust leaks around the connections. If everything sounds good, take your Evo 8 for a test drive.
