Installing a Borla Cat-back Exhaust on Your Gto: Step-by-step for 15+ Horsepower Increase

Installing a Borla Cat-back exhaust on your GTO can significantly enhance your vehicle’s performance and sound. This guide will walk you through the step-by-step process to achieve a horsepower increase of over 15. Follow these instructions carefully to ensure a successful installation.

Tools and Materials Needed

  • Borla Cat-back exhaust system
  • Socket wrench set
  • Jack and jack stands
  • Safety glasses
  • Gloves
  • Torque wrench
  • Lubricant spray

Preparation Steps

Before starting the installation, ensure your vehicle is parked on a level surface. Gather all necessary tools and materials. Make sure to wear safety glasses and gloves to protect yourself during the process.

Step 1: Raise the Vehicle

Using a jack, lift the rear of your GTO and securely place it on jack stands. Ensure the vehicle is stable before proceeding.

Step 2: Remove the Old Exhaust System

Start by using a socket wrench to loosen the bolts connecting the old exhaust system to the catalytic converter. Apply lubricant spray to the bolts if they are rusted or difficult to remove.

Next, disconnect the exhaust hangers from the rubber mounts. You may need to use a pry bar or similar tool to help detach them.

Step 3: Install the Borla Cat-back Exhaust

Begin by positioning the new Borla cat-back exhaust system under the vehicle. Align it with the mounting points and slide the exhaust hangers into the rubber mounts.

Next, connect the exhaust to the catalytic converter. Hand-tighten the bolts first, ensuring everything is aligned correctly.

Step 4: Secure the Exhaust System

Once the exhaust is in place, use a torque wrench to tighten the bolts to the manufacturer’s specifications. This will ensure a secure fit and prevent any leaks.

Step 5: Check for Leaks

Start your vehicle and let it run for a few minutes. Listen for any unusual sounds and check for exhaust leaks around the connections. If you notice any leaks, recheck the tightness of the bolts and adjust as necessary.

Step 6: Lower the Vehicle

After confirming that there are no leaks, carefully lower the vehicle back to the ground using the jack.

Step 7: Take a Test Drive

Take your GTO for a test drive to experience the improved sound and performance. Pay attention to the throttle response and overall driving experience.

Conclusion

Installing a Borla cat-back exhaust on your GTO is a straightforward process that can lead to significant performance gains. By following these steps, you can enjoy an increase of over 15 horsepower and enhance your driving experience.
