Installing an axle-back exhaust on your Subaru WRX can enhance both its performance and sound. This step-by-step guide will walk you through the process, ensuring a successful upgrade whether you’re a seasoned mechanic or a DIY enthusiast.
Tools and Materials Needed
- Socket set and ratchet
- Wrench set
- Jack and jack stands
- Exhaust hanger removal tool
- Penetrating oil (e.g., WD-40)
- New axle-back exhaust kit
- Safety gloves and goggles
Preparation
Before starting, ensure your vehicle is parked on a flat surface. Engage the parking brake and wear safety gear. Use the jack to lift the rear of the car and secure it with jack stands. Apply penetrating oil to the bolts and hangers to ease removal.
Removing the Old Exhaust
Locate the clamps and bolts connecting the existing exhaust to the muffler and tailpipe. Use the appropriate socket or wrench to loosen and remove these fasteners. Carefully detach the exhaust hangers using the exhaust hanger removal tool. Support the exhaust as you remove it to prevent dropping.
Installing the New Axle-Back Exhaust
Position the new exhaust in place, aligning it with the hangers and connection points. Use the provided clamps and bolts to secure the exhaust to the muffler and tailpipe. Tighten all fasteners firmly but avoid over-tightening, which could damage components.
Final Checks and Test Drive
Double-check all connections and fasteners for tightness. Lower the vehicle from the jack stands carefully. Start the engine and listen for leaks or rattles. Take the car for a short test drive to ensure the exhaust is functioning properly and producing the desired sound.
Maintenance Tips
- Regularly inspect the exhaust for rust or damage.
- Clean the exhaust tips to maintain appearance.
- Check for any unusual noises during operation.
By following these steps, you can successfully upgrade your Subaru WRX with a new axle-back exhaust, improving both its performance and sound profile. Happy driving!
