Rev Up Your Audi S5: Discover the Impact of an Aftermarket Exhaust System on Performance and Sound
If you’re an Audi S5 enthusiast looking to elevate your driving experience, one of the most impactful upgrades you can consider is an aftermarket exhaust system. This article will delve into the world of performance exhausts, exploring how they can transform both the sound and performance of your Audi S5.
Understanding the Basics of Exhaust Systems
Before we dive into the specifics of aftermarket exhaust systems, it’s essential to understand how a stock exhaust system works and where it falls short.

Stock Exhaust Systems: The Limitations
Stock exhaust systems are designed with several constraints in mind, including cost, noise regulations, and overall vehicle packaging. These systems often use restrictive tubing and mufflers that dampen the sound and reduce airflow, which can limit the engine’s performance potential.
The Promise of Aftermarket Exhausts
Aftermarket exhaust systems, on the other hand, are engineered to overcome these limitations. Companies like CORSA Performance and Valvetronic Designs specialize in creating systems that enhance both the sound and performance of your vehicle.

The Sound Advantage: How Aftermarket Exhausts Transform Your Audi S5
One of the most immediate and noticeable benefits of an aftermarket exhaust system is the enhanced sound profile.
Reflective Sound Cancellation (RSC) Technology
CORSA Performance’s patented RSC® Technology is a prime example of how aftermarket exhausts can deliver a more aggressive and satisfying sound without the annoying drone at cruising speeds. This technology ensures that you get a deep, aggressive growl during startup and hard acceleration, while maintaining a quiet and drone-free experience when cruising[1].
Valvetronic Exhausts: Control at Your Fingertips
Valvetronic Designs offers another approach with their valved exhaust systems. These systems feature multiple pathways of exhaust flow controlled by a valve that opens and closes, allowing you to switch between a loud, aggressive sound and a quiet, subdued one at the touch of a button. This flexibility is particularly appealing for drivers who want to adjust the sound based on their driving conditions and preferences[3].
Performance Gains: How Aftermarket Exhausts Boost Your Audi S5’s Power
Beyond the sound, aftermarket exhaust systems can significantly enhance the performance of your Audi S5.
Maximizing Airflow and Reducing Back Pressure
CORSA Performance exhaust systems are designed to maximize airflow and minimize back pressure. Using mandrel-bent tubing, these systems ensure smooth, unrestricted airflow from the engine to the tip, which translates to better combustion, more power, and improved fuel efficiency[1].
Tuning and ECU Upgrades
For those looking for even more substantial performance gains, companies like 034Motorsport offer ECU tuning packages that work in conjunction with aftermarket exhaust systems. For example, the 034Motorsport Dynamic+ Performance Software for the Audi S4 and S5 can increase horsepower and torque significantly, with gains of up to 180 HP and 255 TQ depending on the fuel used[2].
Types of Aftermarket Exhaust Systems: Choosing the Right One for Your Audi S5
When it comes to selecting an aftermarket exhaust system, there are several options to consider, each with its own set of benefits.
Cat-Back Exhaust Systems
Cat-back exhaust systems replace the stock exhaust from the catalytic converter to the tailpipe. These systems are straightforward to install and do not require any modifications to the emissions equipment, making them a legal and easy way to boost both sound and performance[1].
Axle-Back Exhaust Systems
Axle-back exhaust systems focus primarily on sound enhancement by replacing the muffler and tips. While they may not offer the same performance gains as cat-back or full exhaust systems, they provide a range of sound profiles to suit your driving style[1].
Valved Exhaust Systems
Valved exhaust systems, as mentioned earlier, offer the flexibility to switch between different sound profiles. These systems are ideal for drivers who want to adjust the sound based on their driving conditions and preferences[3].
Practical Considerations and Installation
When considering an aftermarket exhaust system, there are several practical aspects to keep in mind.
Installation Complexity
The complexity of installation varies depending on the type of system. Cat-back and axle-back systems are generally easier to install and can often be done at home with basic tools. However, valved exhaust systems may require more expertise and specialized tools[1][3].
Legal and Emissions Compliance
It’s crucial to ensure that any aftermarket exhaust system you choose complies with local emissions regulations. Cat-back systems are generally safe in this regard, as they do not alter the emissions equipment[1].
Maintenance and Durability
Aftermarket exhaust systems are typically built with high-quality materials and are designed to last longer than stock systems. However, regular maintenance, such as checking for leaks and ensuring proper fitment, is still necessary to maintain performance and sound quality.
Real-World Examples and User Experiences
To get a better understanding of how these systems perform in real-world scenarios, let’s look at some user experiences and examples.
User Testimonials
“I recently installed a CORSA cat-back exhaust on my Audi S5, and the difference is night and day. The sound is aggressive but not overwhelming, and I’ve noticed a significant improvement in throttle response and power,” says John, a veteran Audi enthusiast.

Key Points to Consider When Upgrading Your Audi S5’s Exhaust
Here are some key points to keep in mind when upgrading your Audi S5’s exhaust system:
- Sound Profile: Choose an exhaust system that matches your desired sound profile. CORSA’s RSC® Technology and Valvetronic’s valved systems offer different approaches to sound control.
- Performance Gains: Consider the type of performance gains you’re looking for. Cat-back systems offer a balance of sound and performance, while ECU tuning can provide more substantial power increases.
- Installation: Ensure you understand the installation complexity and whether it requires professional assistance.
- Legal Compliance: Verify that the system complies with local emissions regulations.
- Maintenance: Regularly check and maintain your exhaust system to ensure it continues to perform optimally.
Upgrading your Audi S5 with an aftermarket exhaust system can be a transformative experience, enhancing both the sound and performance of your car. Whether you opt for a CORSA cat-back system, a Valvetronic valved exhaust, or combine these with ECU tuning from 034Motorsport, the results are sure to impress.
As Brandon Arpin from Valvetronic Designs puts it, “A Valvetronic or Valved Exhaust is an exhaust that has multiple pathways of exhaust flow, all controlled by a valve that opens and closes. This valve allows you to switch between different sound profiles, giving you the best of both worlds.”
In the end, the decision to upgrade your exhaust system is about more than just performance or sound; it’s about enhancing your overall driving experience and unlocking the full potential of your Audi S5. So why settle for a stock exhaust when you can rev up your Audi S5 and enjoy the thrill of a more powerful and sonically pleasing ride?
