The installation of a Perrin WRX downpipe can significantly enhance the performance and sound of your vehicle. This guide will walk you through the step-by-step process, ensuring that you can complete the installation with confidence.
Tools and Materials Needed
- Socket set (including 10mm, 14mm, and 17mm sockets)
- Wrench set
- Torque wrench
- Jack and jack stands
- Safety glasses
- Gloves
- Perrin downpipe
- New gaskets (if necessary)
- Exhaust sealant (optional)
Step 1: Prepare Your Vehicle
Before starting the installation, ensure your vehicle is parked on a flat surface. Engage the parking brake and wear your safety glasses and gloves. Use the jack to lift the front of the car and secure it with jack stands.
Step 2: Remove the Stock Downpipe
Locate the stock downpipe. It is typically connected to the turbocharger and the rest of the exhaust system. Start by removing the heat shield if your vehicle has one, using the appropriate socket or wrench.
Next, disconnect the O2 sensors by carefully unplugging the connectors. Make sure to note their positions for reinstallation.
Now, loosen the bolts connecting the downpipe to the turbo and the exhaust system. Keep track of the bolts and nuts, as you will need them for the new downpipe installation.
Step 3: Install the Perrin Downpipe
With the stock downpipe removed, it’s time to install the Perrin downpipe. Align it with the turbo and the exhaust system. Make sure it fits snugly and that the bolt holes line up correctly.
Before tightening the bolts, place the new gaskets (if applicable) in position. If you prefer, you can apply a small amount of exhaust sealant to ensure a tight seal.
Using your torque wrench, tighten the bolts to the manufacturer’s specifications, ensuring that you do not overtighten and risk damaging the components.
Step 4: Reconnect O2 Sensors
Reconnect the O2 sensors to their respective connectors. Double-check that they are securely plugged in and not pinched or damaged during the installation.
Step 5: Reinstall Heat Shield (if applicable)
If your vehicle originally had a heat shield, reinstall it over the new downpipe using the original bolts. This will help protect the surrounding components from heat damage.
Step 6: Lower the Vehicle and Test
Once everything is securely in place, carefully lower the vehicle back to the ground. Start the engine and listen for any unusual sounds. Check for leaks around the downpipe connections.
Step 7: Final Checks
After a short test drive, recheck the downpipe connections and O2 sensors to ensure everything remains tight and secure. It’s essential to make sure that the installation is complete and that there are no leaks.
Conclusion
Installing a Perrin WRX downpipe can greatly improve your vehicle’s performance and sound. By following this step-by-step guide, you can ensure a successful installation. Always remember to take your time and double-check your work for the best results.
