This article will guide you through the process of installing a Milltek Sport Exhaust on your B9 S4, detailing the benefits and steps involved.
Benefits of Milltek Sport Exhaust
Upgrading to a Milltek Sport Exhaust offers several advantages for your B9 S4:
- Enhanced Sound: The Milltek exhaust system provides a deeper, more aggressive sound that enhances the driving experience.
- Improved Performance: This exhaust is designed to reduce back pressure, allowing for better engine efficiency and performance gains.
- Quality Materials: Made from high-quality stainless steel, Milltek exhausts are built to last and resist corrosion.
- Weight Reduction: The Milltek system is often lighter than the stock exhaust, contributing to better handling and performance.
Tools Required for Installation
Before you begin the installation, make sure you have the following tools on hand:
- Socket set (including 13mm and 15mm sockets)
- Ratchet and extension
- Torque wrench
- Jack and jack stands
- Rubber mallet
- Safety glasses and gloves
Installation Steps
Step 1: Prepare Your Vehicle
Start by parking your B9 S4 on a flat surface. Engage the parking brake and ensure the engine is cool. Use a jack to lift the vehicle and secure it with jack stands for safety.
Step 2: Remove the Stock Exhaust
Using the socket set, remove the bolts securing the stock exhaust system to the downpipe. Carefully detach the exhaust hangers using a rubber mallet if necessary. Once all connections are loose, remove the stock exhaust from the vehicle.
Step 3: Install the Milltek Exhaust
Begin by positioning the Milltek exhaust under the vehicle. Align it with the downpipe and exhaust hangers. Secure the connections using the provided bolts, ensuring everything is tight but not over-torqued. Follow the manufacturer’s specifications for torque settings.
Step 4: Check Alignment and Hanger Placement
Once the Milltek exhaust is in place, check the alignment. Ensure that the exhaust tips are centered and that there is adequate clearance from the vehicle’s undercarriage. Adjust the hangers as necessary to achieve the correct positioning.
Step 5: Final Checks and Lower the Vehicle
After confirming that everything is aligned correctly, perform a final check on all bolts and connections. Once satisfied, lower the vehicle from the jack stands and remove the jack.
Post-Installation Tips
After installing your Milltek Sport Exhaust, consider the following tips:
- Take your B9 S4 for a test drive to experience the new sound and performance.
- Monitor for any leaks or unusual noises during the first few drives.
- Regularly check the exhaust system for any loose bolts or hangers.
Conclusion
Installing a Milltek Sport Exhaust on your B9 S4 is a rewarding modification that enhances both sound and performance. With the right tools and careful installation, you can enjoy the benefits of improved exhaust flow and a more aggressive tone. Happy driving!
