The GR Corolla is known for its impressive performance and sporty design, making it a popular choice among car enthusiasts. One of the essential upgrades that can enhance its performance and sound is the exhaust system. In this article, we will provide a detailed step-by-step guide for installing a GR Corolla exhaust, along with tips to ensure a perfect fit and seal.
Tools and Materials Needed
- Socket wrench set
- Torque wrench
- Jack and jack stands
- Exhaust gasket
- New exhaust system
- Anti-seize compound
- Safety glasses
- Gloves
Before starting the installation, gather all the necessary tools and materials. This preparation will help streamline the process and ensure you have everything on hand.
Step 1: Prepare the Vehicle
Begin by ensuring the vehicle is parked on a flat surface. Engage the parking brake and wear safety glasses and gloves. Use a jack to lift the rear of the vehicle and secure it with jack stands. This will provide better access to the exhaust system.
Step 2: Remove the Old Exhaust System
Locate the exhaust hangers and use a socket wrench to remove any bolts securing the exhaust to the undercarriage. Carefully slide the exhaust off the hangers and remove it from the vehicle. Be cautious as the old exhaust may be heavy.
Step 3: Inspect the Exhaust Flange
After removing the old exhaust, inspect the exhaust flange for any signs of damage or corrosion. A damaged flange can lead to leaks in the new exhaust system. If necessary, clean the flange with a wire brush to ensure a smooth surface for the new exhaust gasket.
Step 4: Install the New Exhaust Gasket
Place the new exhaust gasket onto the flange. Ensure it is aligned properly with the bolt holes. This gasket is crucial for creating a tight seal between the exhaust components.
Step 5: Position the New Exhaust System
Carefully position the new exhaust system under the vehicle. Align it with the exhaust flange and hangers. It may be helpful to have a friend assist you in holding the exhaust in place while you secure it.
Step 6: Secure the Exhaust System
Using the socket wrench, tighten the bolts on the exhaust flange. Be sure to follow the manufacturer’s torque specifications to avoid damaging the components. After securing the flange, attach the exhaust hangers to their respective locations.
Step 7: Apply Anti-Seize Compound
To prevent future rust and make future installations easier, apply a small amount of anti-seize compound to the threads of the bolts. This will help ensure that the bolts can be removed easily when necessary.
Step 8: Check for Leaks
Once the installation is complete, start the engine and listen for any unusual sounds. Check for exhaust leaks by feeling around the connections with your hand. If you notice any leaks, you may need to tighten the bolts further or reposition the exhaust system.
Step 9: Lower the Vehicle
After confirming that there are no leaks, turn off the engine and carefully lower the vehicle back to the ground. Remove the jack stands and ensure everything is secure before taking the car for a test drive.
Conclusion
Installing a new exhaust system on your GR Corolla can significantly enhance its performance and sound. By following these steps and tips, you can ensure a perfect fit and seal, leading to a successful installation. Always remember to take your time and double-check each step for the best results.
