Step-by-step Wrx Turbo Back Exhaust Installation Guide with OEM and Aftermarket Options

Installing a turbo back exhaust on your WRX can enhance performance and sound. This guide provides a detailed step-by-step process for both OEM and aftermarket options.

Tools and Materials Needed

  • Socket set
  • Wrench set
  • Jack and jack stands
  • Torque wrench
  • Exhaust hanger removal tool
  • New exhaust gaskets
  • Lubricant (like WD-40)
  • Safety glasses
  • Gloves

Preparation Steps

Before starting the installation, ensure your vehicle is parked on a level surface. Gather all tools and materials listed above. Make sure to wear safety glasses and gloves for protection.

Step 1: Lift the Vehicle

Using a jack, lift the rear of your WRX and secure it with jack stands. Ensure the vehicle is stable before proceeding.

Step 2: Remove the Old Exhaust

Starting from the back, locate the exhaust hangers. Use the exhaust hanger removal tool to detach the exhaust from the hangers. Then, remove the bolts connecting the exhaust to the turbo and mid-pipe.

Installing the New Exhaust

With the old exhaust removed, it’s time to install your new turbo back exhaust. This process will vary slightly depending on whether you have an OEM or aftermarket system.

Step 3: Install the Downpipe

Begin with the downpipe. Align it with the turbo and secure it with bolts. Ensure that you use new gaskets to prevent leaks. Tighten the bolts to the manufacturer’s specifications using a torque wrench.

Step 4: Connect the Mid-Pipe

Next, attach the mid-pipe to the downpipe. Again, use new gaskets and secure with bolts. Make sure everything is aligned properly to avoid any stress on the exhaust system.

Step 5: Attach the Axle-Back

Finally, connect the axle-back section of the exhaust. Ensure it is hanging properly on the exhaust hangers and tighten the bolts to secure it in place.

Final Steps

After everything is installed, double-check all connections and hangers. Start the engine and listen for any leaks. If everything sounds good, lower the vehicle back to the ground.

OEM vs Aftermarket Exhaust Options

When choosing between OEM and aftermarket options, consider the following:

  • OEM Exhaust: Typically offers a quieter operation and maintains factory specifications.
  • Aftermarket Exhaust: Can provide increased performance and a more aggressive sound, but may vary in quality.

Conclusion

Installing a turbo back exhaust on your WRX is a rewarding project that can enhance your vehicle’s performance. By following this guide, you can confidently choose between OEM and aftermarket options and complete the installation successfully.
