The Subaru WRX is a popular choice among car enthusiasts, known for its performance and tuning potential. One of the modifications that can significantly enhance the performance of your WRX is the installation of high flow catalytic converters. In this article, we will guide you through the step-by-step installation of Flowmaster high flow catalytic converters on your Subaru WRX.
Tools and Materials Needed
- Flowmaster high flow catalytic converters
- Socket set
- Wrench set
- Jack and jack stands
- Torque wrench
- Exhaust pipe cutter (if necessary)
- Safety goggles
- Gloves
Preparation
Before starting the installation process, it is essential to prepare your workspace and gather all necessary tools and materials. Make sure your Subaru WRX is parked on a flat surface and allow the exhaust system to cool down completely to avoid burns.
Step 1: Lifting the Vehicle
Using a jack, lift the front of the vehicle and secure it with jack stands. Ensure that the car is stable before proceeding with the installation.
Step 2: Removing the Stock Catalytic Converters
Locate the stock catalytic converters under the vehicle. Using a socket set, remove the bolts securing the catalytic converters to the exhaust system. If the bolts are rusted or stuck, you may need to use penetrating oil to loosen them.
Once the bolts are removed, carefully detach the stock catalytic converters from the exhaust system. Be cautious of any exhaust hangers that may still be attached and remove them as necessary.
Step 3: Preparing the Flowmaster High Flow Catalytic Converters
Before installing the Flowmaster high flow catalytic converters, inspect them for any damage. Ensure that all necessary gaskets and hardware are included in the package. If needed, trim the exhaust pipes to fit the new converters using an exhaust pipe cutter.
Step 4: Installing the Flowmaster Catalytic Converters
Position the Flowmaster high flow catalytic converters in place where the stock units were removed. Ensure that the inlet and outlet pipes align correctly with the exhaust system.
Using the provided bolts and gaskets, secure the new catalytic converters to the exhaust system. Start by hand-tightening the bolts to ensure proper alignment, then use a torque wrench to tighten them to the manufacturer’s specifications.
Step 5: Reattaching Exhaust Hangers
After securing the Flowmaster catalytic converters, reattach any exhaust hangers that were removed during the process. Ensure that the exhaust system is properly supported and free from any strain.
Step 6: Lowering the Vehicle
Once everything is secured and in place, carefully lower the vehicle back to the ground using the jack. Remove the jack stands and ensure the vehicle is stable.
Step 7: Testing for Leaks
Start the engine and let it idle for a few minutes. Listen for any unusual sounds and check for exhaust leaks around the new catalytic converters. If you notice any leaks, recheck the bolts and connections to ensure they are tight.
Step 8: Final Inspection
After confirming that there are no leaks, perform a final inspection of the installation. Make sure all tools and materials are removed from under the vehicle, and double-check that everything is secure.
Conclusion
Installing Flowmaster high flow catalytic converters on your Subaru WRX can improve performance and enhance the overall driving experience. By following these step-by-step instructions, you can successfully complete the installation and enjoy the benefits of your new exhaust system. Always remember to follow safety precautions and consult a professional if you are uncertain about any part of the process.
