Installing a Perrin Turbo Downpipe on your Subaru WRX can enhance performance and sound. This guide provides a step-by-step approach to ensure a smooth installation process.
Tools and Materials Needed
- Perrin Turbo Downpipe
- Socket set
- Torque wrench
- Jack and jack stands
- Safety glasses
- Gloves
- PB Blaster or penetrating oil
Before starting the installation, gather all necessary tools and materials. Ensure you have a clean workspace and that your vehicle is parked on a flat surface.
Preparation
Begin by ensuring your Subaru WRX is cool to the touch. Wear safety glasses and gloves for protection throughout the process.
Lift the Vehicle
Using a jack, lift the front of your WRX and secure it with jack stands. This will give you access to the undercarriage for the installation.
Removing the Stock Downpipe
Locate the stock downpipe, which connects the turbocharger to the exhaust system. Begin by spraying PB Blaster on the bolts to loosen any rust or corrosion.
Disconnecting the Exhaust Components
Remove the bolts that connect the downpipe to the turbo and the exhaust system. This may require a socket wrench and extension for better reach.
Removing the Stock Downpipe
Once the bolts are removed, carefully maneuver the stock downpipe out of its position. Be cautious of any remaining exhaust hangers that may need to be disconnected.
Installing the Perrin Turbo Downpipe
With the stock downpipe removed, it’s time to install the Perrin Turbo Downpipe. Align it with the turbo and exhaust system connection points.
Securing the Downpipe
Insert the bolts through the downpipe flanges and tighten them by hand first. This will ensure proper alignment before fully tightening.
Tightening the Bolts
Using a torque wrench, tighten the bolts to the manufacturer’s specifications. This step is crucial to prevent any exhaust leaks.
Reconnecting Exhaust Components
Reconnect any exhaust hangers or components that were removed during the process. Ensure everything is secure and properly aligned.
Checking for Leaks
Before lowering the vehicle, start the engine and let it run for a few minutes. Check for any exhaust leaks around the downpipe connections.
Final Steps
Once you have confirmed there are no leaks, lower the vehicle carefully and remove the jack stands.
Test Drive
Take your Subaru WRX for a test drive to experience the improved performance and sound. Listen for any unusual noises that may indicate a problem.
Conclusion
Installing a Perrin Turbo Downpipe can significantly enhance your Subaru WRX’s performance. Follow these steps carefully to ensure a successful installation.
