Installing a COBB turbo downpipe is a popular upgrade for Subaru WRX enthusiasts looking to enhance performance. This guide will walk you through the steps to install your downpipe, ensuring you achieve optimal results.
Tools and Materials Needed
- COBB turbo downpipe
- Socket set
- Wrench set
- Torque wrench
- Jack and jack stands
- Safety goggles
- Gloves
- Anti-seize compound
Preparation
Before you begin the installation, ensure you have all the necessary tools and materials ready. It’s also important to work in a well-ventilated area and wear safety gear to protect yourself during the process.
Step 1: Lift the Vehicle
Using a jack, lift your Subaru WRX and secure it with jack stands. Make sure the car is stable before proceeding to the next steps.
Step 2: Remove the Undertray
Locate and remove the undertray from the bottom of the vehicle. This may involve unscrewing several bolts or screws. Set the undertray aside for reinstallation later.
Step 3: Disconnect the Exhaust System
Loosen the bolts connecting the downpipe to the turbocharger and the mid-pipe. Carefully disconnect the exhaust system, ensuring not to damage any components.
Step 4: Remove the Stock Downpipe
With the exhaust system disconnected, remove the stock downpipe. This may require some maneuvering to free it from its mounts. Be cautious of any remaining gaskets or seals.
Step 5: Install the COBB Turbo Downpipe
Position the COBB turbo downpipe in place, ensuring it aligns correctly with the turbocharger and mid-pipe. Use new gaskets if necessary, and apply anti-seize compound to the bolts to prevent future seizing.
Step 6: Secure the Downpipe
Using your socket and wrench set, tighten the bolts connecting the downpipe to the turbocharger and mid-pipe. Follow the manufacturer’s torque specifications for optimal installation.
Step 7: Reinstall the Exhaust System
Reconnect the exhaust system, ensuring all connections are secure. Double-check that all bolts are tightened according to specifications.
Step 8: Replace the Undertray
Reattach the undertray to the bottom of the vehicle. Ensure all screws or bolts are tightened properly to avoid rattling or damage.
Final Checks
Once everything is reassembled, lower the vehicle from the jack stands. Start the engine and check for any leaks or unusual noises. If everything looks good, take your Subaru WRX for a test drive to experience the performance boost!
Conclusion
Installing a COBB turbo downpipe can significantly enhance the performance of your Subaru WRX. By following this step-by-step guide, you can ensure a successful installation and enjoy the benefits of increased power and efficiency.
