The Audi S3 2.0 TFSI is a popular choice among car enthusiasts looking to enhance performance and sound. One of the most effective modifications for this vehicle is the installation of a CTS Turbo downpipe. This article will guide you through the benefits, installation process, and considerations when upgrading to a CTS Turbo downpipe.
Benefits of Upgrading to a CTS Turbo Downpipe
Installing a CTS Turbo downpipe offers several advantages for your Audi S3. Here are some key benefits:
- Increased Power: A downpipe allows for better exhaust flow, which can lead to significant power gains.
- Improved Sound: The downpipe enhances the exhaust note, giving your S3 a more aggressive sound.
- Better Turbo Response: With reduced back pressure, the turbo can spool faster, improving throttle response.
- Weight Reduction: Aftermarket downpipes may weigh less than stock components, contributing to overall vehicle weight savings.
Tools and Materials Needed
Before starting the installation, gather the necessary tools and materials:
- CTS Turbo downpipe
- Socket set
- Wrench set
- Torque wrench
- Jack and jack stands
- Safety goggles
- Gloves
- Exhaust gasket (if needed)
Installation Process
Step 1: Prepare Your Vehicle
Begin by parking your Audi S3 on a level surface. Engage the parking brake and ensure the engine is cool. Use a jack to lift the front of the vehicle and secure it with jack stands.
Step 2: Remove the Stock Downpipe
Start by disconnecting the exhaust system from the stock downpipe. This usually involves removing bolts and clamps. Be sure to keep any hardware that you will need for the new downpipe installation.
Next, remove the oxygen sensors from the stock downpipe. Take care not to damage the sensors, as they will be reused. Finally, unbolt the downpipe from the turbo and carefully remove it from the vehicle.
Step 3: Install the CTS Turbo Downpipe
Position the CTS Turbo downpipe in place, aligning it with the turbo and exhaust system. If your downpipe requires a new gasket, install it now. Secure the downpipe to the turbo using the original bolts, ensuring you follow the manufacturer’s torque specifications.
Step 4: Reconnect the Exhaust System
Reconnect the exhaust system to the new downpipe. Ensure all clamps and bolts are tightened securely. Reinstall the oxygen sensors in their respective locations, making sure they are properly seated.
Step 5: Lower the Vehicle and Test
Carefully lower your Audi S3 back to the ground. Start the engine and listen for any unusual sounds that may indicate a leak. Check for any warning lights on the dashboard and ensure everything is functioning correctly.
Considerations After Installation
After installing the CTS Turbo downpipe, consider the following:
- Tuning: A downpipe can affect your vehicle’s air-fuel ratio, so consider getting an ECU tune to optimize performance.
- Legal Regulations: Check local emissions laws, as some downpipes may not be street legal.
- Maintenance: Regularly inspect the downpipe and exhaust system for leaks or damage.
Conclusion
Upgrading to a CTS Turbo downpipe is a worthwhile modification for Audi S3 2.0 TFSI owners seeking increased power and improved sound. With the right tools and careful installation, this mod can significantly enhance your driving experience. Always remember to consider tuning and local regulations after making such modifications.
