Installing a performance exhaust system on your Audi S4 can significantly enhance both sound and power, providing a more thrilling driving experience. In this guide, we will walk you through the step-by-step process of installing a performance exhaust system for around $1,200.
Tools and Materials Needed
- Performance exhaust system
- Socket wrench set
- Torque wrench
- Jack and jack stands
- Safety goggles
- Gloves
- Exhaust hanger removal tool
- Lubricant (WD-40 or similar)
Preparation
Before starting the installation, ensure you have all the necessary tools and materials. It is also advisable to work in a well-ventilated area and wear safety gear to protect yourself.
Step 1: Lift the Vehicle
Using a jack, lift the Audi S4 and secure it with jack stands. This will provide you with ample space to work underneath the vehicle.
Step 2: Remove the Stock Exhaust
Start by spraying lubricant on the exhaust hangers to make removal easier. Use the exhaust hanger removal tool to detach the hangers from the stock exhaust system.
Next, use your socket wrench to remove the bolts connecting the exhaust to the catalytic converter and the mufflers. Carefully lower the stock exhaust system and set it aside.
Step 3: Prepare the New Exhaust System
Unbox your new performance exhaust system and lay out all the components. Familiarize yourself with the parts and the installation instructions provided by the manufacturer.
Step 4: Install the New Exhaust System
Begin by attaching the new exhaust pipes to the catalytic converter. Ensure that the pipes are aligned correctly and use the provided bolts to secure them. Tighten the bolts with a torque wrench to the manufacturer’s specifications.
Next, hang the exhaust system onto the hangers. Make sure each section is properly aligned and secured to prevent any vibrations during operation.
Step 5: Final Checks
Once the new exhaust system is installed, double-check all connections and ensure that everything is tight. Lower the vehicle back to the ground and start the engine to listen for any unusual sounds.
Benefits of a Performance Exhaust System
Upgrading to a performance exhaust system can provide several benefits, including:
- Enhanced Sound: A performance exhaust system typically offers a deeper, more aggressive sound compared to the stock exhaust.
- Increased Power: Improved exhaust flow can lead to better engine performance and increased horsepower.
- Weight Reduction: Many aftermarket exhaust systems are lighter than factory options, reducing overall vehicle weight.
- Better Fuel Efficiency: Enhanced exhaust flow can contribute to improved fuel efficiency under certain driving conditions.
Conclusion
Installing a performance exhaust system on your Audi S4 is a rewarding project that can enhance your vehicle’s sound and performance. With the right tools and a little patience, you can complete the installation yourself for around $1,200. Enjoy your upgraded driving experience!
