Upgrading your Scion FR-S with a Borla cat-back exhaust system can significantly enhance its performance and sound. This guide will take you through the step-by-step process of installing the exhaust system.
Tools and Materials Needed
- Jack and jack stands
- Socket set
- Wrench set
- Torque wrench
- Rubber mallet
- Safety glasses
- Gloves
- Borla cat-back exhaust system
Before starting the installation, ensure that you have all the necessary tools and materials at hand. This will make the process smoother and more efficient.
Step 1: Prepare Your Vehicle
Begin by parking your Scion FR-S on a level surface. Engage the parking brake and ensure the engine is off. For safety, wear safety glasses and gloves throughout the process.
Next, use the jack to lift the rear of the vehicle and secure it with jack stands. This will provide you with adequate space to work underneath the car.
Step 2: Remove the Stock Exhaust System
Locate the stock exhaust system. Start by loosening the bolts that connect the exhaust to the catalytic converter using your socket set. Make sure to keep these bolts for the new installation.
Next, move to the hangers that support the exhaust system. Use a rubber mallet to gently tap the exhaust off the hangers, taking care not to damage them.
Once the exhaust is free from the hangers, carefully remove it from the vehicle. It may be helpful to have a friend assist you with this step.
Step 3: Install the Borla Cat-back Exhaust
With the stock exhaust removed, it’s time to install the Borla cat-back exhaust system. Start by positioning the new exhaust in place, aligning it with the existing hangers.
Once aligned, slide the exhaust onto the catalytic converter and secure it using the bolts you saved from the previous step. Ensure that everything is tight, but do not fully torque the bolts yet.
Securing the Exhaust System
After securing the exhaust to the catalytic converter, attach the hangers to their respective mounts. Make sure the exhaust is properly aligned and does not touch any other components.
Once everything is in place, use your torque wrench to tighten the bolts to the manufacturer’s specifications. This ensures a secure fit and prevents any leaks.
Step 4: Check for Leaks and Final Adjustments
With the Borla exhaust installed, it’s crucial to check for any leaks. Start the engine and let it idle for a few minutes while inspecting the connections for any signs of exhaust leaks.
If you notice any leaks, turn off the engine and tighten the bolts further. Make any necessary adjustments to ensure the exhaust is properly aligned.
Step 5: Lower the Vehicle
Once you are satisfied that there are no leaks and everything is secure, it’s time to lower the vehicle. Carefully remove the jack stands and lower the car back to the ground.
Step 6: Test Drive Your Scion FR-S
After the installation, take your Scion FR-S for a test drive. Pay attention to the sound of the exhaust and the overall performance of the vehicle. The Borla cat-back exhaust should provide a more aggressive sound and improved performance.
Enjoy your enhanced driving experience and the benefits of your new exhaust system!
