The Audi S4 is known for its luxurious feel and impressive performance. However, many enthusiasts look for ways to enhance the driving experience further. One popular modification is the resonator delete, which can improve both sound and power. In this guide, we will walk you through the DIY process of performing a resonator delete on your Audi S4 for just $100.
What is a Resonator Delete?
A resonator delete involves removing the resonator from your car’s exhaust system. The resonator is designed to reduce noise and modify exhaust tones. By removing it, you can achieve a more aggressive sound and potentially increase horsepower. This modification is particularly popular among car enthusiasts who want a sportier driving experience.
Benefits of a Resonator Delete
- Improved Sound: A resonator delete typically results in a deeper and more aggressive exhaust note.
- Increased Power: By reducing back pressure, your engine may perform better, leading to a slight increase in horsepower.
- Cost-Effective: This modification can be done for around $100, making it an affordable upgrade.
- Easy Installation: With basic tools, many car enthusiasts can perform this modification themselves.
Tools and Materials Needed
- Tools:
- Socket wrench set
- Jack and jack stands
- Cutting tool (sawzall or pipe cutter)
- Measuring tape
- Safety goggles
- Gloves
- Materials:
- Replacement pipe or exhaust tip
- Exhaust clamps
- High-temperature exhaust sealant (optional)
Step-by-Step Guide to Perform a Resonator Delete
Step 1: Prepare Your Vehicle
Before starting, ensure your vehicle is parked on a flat surface and the engine is cool. Use the jack to lift the rear of the car and secure it with jack stands for safety.
Step 2: Locate the Resonator
Under the vehicle, locate the resonator in the exhaust system. It is typically a round or oval-shaped component situated between the catalytic converter and the muffler.
Step 3: Measure and Cut
Using your measuring tape, determine the length of the section you need to cut out. Mark the area clearly. Use the cutting tool to carefully remove the resonator from the exhaust system.
Step 4: Install the Replacement Pipe
Once the resonator is removed, take the replacement pipe and fit it into the space where the resonator was. Ensure that it aligns properly with the existing exhaust system.
Step 5: Secure the Exhaust System
Use exhaust clamps to secure the replacement pipe in place. Ensure that all connections are tight to prevent any leaks. If desired, apply high-temperature exhaust sealant for additional security.
Step 6: Lower the Vehicle and Test
Carefully lower the vehicle back to the ground. Start the engine and listen for any unusual sounds. Take the car for a short drive to ensure everything is functioning correctly and enjoy the new sound of your Audi S4!
Potential Drawbacks
While a resonator delete can provide several benefits, there are some potential drawbacks to consider:
- Increased Noise: The sound may be too loud for some drivers, especially during long drives.
- Possible Legal Issues: In some areas, modifications that increase exhaust noise may not be street legal.
- Warranty Concerns: Modifying the exhaust system could potentially void certain aspects of your vehicle’s warranty.
Conclusion
A DIY resonator delete on your Audi S4 can enhance both sound and performance for a minimal cost. With the right tools and a little bit of time, you can achieve a more aggressive exhaust note and possibly increase your vehicle’s horsepower. However, always consider the potential drawbacks and ensure that any modifications comply with local regulations. Enjoy your upgraded Audi S4!
