Installing an aftermarket axle-back exhaust on your Subaru WRX can enhance both the sound and performance of your vehicle. Proper installation ensures safety and optimal function. Follow these step-by-step tips to achieve a successful upgrade.
Preparation Before Installation
Gather all necessary tools and parts before starting. Typical tools include a jack, jack stands, socket set, WD-40, and possibly a torque wrench. Ensure your new exhaust is compatible with your Subaru WRX model.
Park your vehicle on a flat surface, engage the parking brake, and disconnect the negative battery terminal for safety. Lift the rear of the car using a jack and secure it with jack stands.
Removing the Stock Exhaust
Locate the stock axle-back exhaust components. Spray the bolts and clamps with WD-40 to loosen rust and debris. Use a socket wrench to carefully remove the clamps and bolts holding the stock exhaust in place.
Gently detach the stock exhaust from the mid-pipe and muffler. Be cautious to avoid damaging surrounding components. Once removed, inspect the area for any rust or damage.
Installing the Aftermarket Axle-Back Exhaust
Align the new exhaust with the mid-pipe and muffler connections. Slide the clamps into position and hand-tighten the bolts to hold the exhaust in place. Ensure the exhaust tips are properly aligned and centered.
Use a torque wrench to tighten the clamps and bolts to the manufacturer’s specified torque values. Double-check all connections for security and proper fit.
Final Checks and Tips
Lower the vehicle from the jack stands and reconnect the negative battery terminal. Start the engine and listen for any leaks or rattles. Check the exhaust tips for proper alignment.
Take the vehicle for a short test drive to ensure everything is functioning correctly. Listen for any unusual sounds and verify that the exhaust is securely mounted.
Additional Tips for Success
- Always wear safety glasses and gloves during installation.
- Work in a well-ventilated area to avoid inhaling fumes.
- Consult your exhaust manufacturer’s instructions for specific torque specs.
- Consider applying anti-seize compound to bolts to facilitate future removal.
With patience and attention to detail, installing an aftermarket axle-back exhaust on your Subaru WRX can be a rewarding DIY project that enhances your car’s sound and style.
