Hey guys! Let's dive into the world of the 2019 Audi S5 Sportback exhaust systems. If you're looking to boost your car's performance, sound, and overall driving experience, upgrading your exhaust is a fantastic place to start. In this guide, we'll cover everything you need to know, from the benefits of upgrading to the different types of exhausts available, and even some top recommendations.

Why Upgrade Your 2019 Audi S5 Sportback Exhaust?

Upgrading your 2019 Audi S5 Sportback exhaust system offers a plethora of benefits that can significantly enhance your driving experience. Let's explore these advantages in detail:

• Enhanced Performance: One of the primary reasons car enthusiasts opt for an exhaust upgrade is the promise of improved performance. The stock exhaust systems in many vehicles, including the 2019 Audi S5 Sportback, often come with design constraints aimed at reducing noise and emissions. These constraints can, unfortunately, restrict the engine's ability to breathe efficiently. By installing an aftermarket exhaust system, you can reduce backpressure, allowing exhaust gases to flow more freely. This, in turn, can lead to noticeable gains in horsepower and torque, especially in the mid to high RPM ranges. Imagine feeling that extra surge of power as you accelerate – it's an exhilarating experience that transforms your daily commute into something much more engaging.
• Improved Sound: The sound of your car is a huge part of the driving experience. The factory exhaust on the S5 Sportback is okay, but it often leaves something to be desired for those craving a more aggressive and sporty sound. An aftermarket exhaust system can provide a deeper, throatier exhaust note that announces your presence with authority. Whether you prefer a subtle rumble or a full-on roar, there's an exhaust system out there that can match your desired sound profile. The sound improvement isn't just about being loud; it's about creating a more emotional and connected driving experience. The right exhaust note can make every drive feel more special.
• Weight Reduction: Many aftermarket exhaust systems are crafted from lighter materials such as stainless steel or titanium. These materials not only offer superior durability but also contribute to weight reduction compared to the heavier stock systems. Reducing the overall weight of your vehicle can lead to improved handling, better acceleration, and even slight gains in fuel efficiency. Every pound counts when it comes to performance, and an exhaust upgrade is an easy way to shave off some extra weight.
• Aesthetic Appeal: Let's face it: the way your car looks matters. An aftermarket exhaust system often comes with polished tips and a more aggressive design that can enhance the visual appeal of your 2019 Audi S5 Sportback. These visual upgrades can complement other modifications you might have made to your vehicle, creating a cohesive and customized look. Whether you're going for a subtle and refined appearance or a bold and aggressive style, an aftermarket exhaust can help you achieve your desired aesthetic.
• Increased Resale Value: While it might seem counterintuitive, certain high-quality aftermarket parts can actually increase the resale value of your vehicle. If you choose a reputable brand and install the exhaust system professionally, it can be seen as a desirable upgrade by potential buyers. This is especially true if you keep the original exhaust system, allowing you to revert to stock if needed. Investing in quality parts shows that you've taken good care of your vehicle and are willing to invest in its performance and appearance.

Types of Exhaust Systems for the 2019 Audi S5 Sportback

Understanding the different types of exhaust systems available for your 2019 Audi S5 Sportback is crucial in making an informed decision. Each type offers unique characteristics in terms of performance, sound, and cost. Let's explore the common options:

• Cat-Back Systems: A cat-back exhaust system replaces everything from the catalytic converters back to the exhaust tips. This is a popular choice for many enthusiasts because it offers a good balance of performance gains, sound improvement, and affordability. Cat-back systems typically include a new mid-pipe, muffler, and exhaust tips. They are designed to be a direct replacement for the factory system, making installation relatively straightforward. With a cat-back system, you can expect a noticeable improvement in exhaust flow, resulting in modest gains in horsepower and torque. The sound is also enhanced, providing a deeper and more aggressive tone without being overly loud.
• Axle-Back Systems: An axle-back exhaust system is a more budget-friendly option that replaces the components from the rear axle to the exhaust tips. This usually includes the muffler and exhaust tips. Axle-back systems are primarily focused on improving the sound of your vehicle, offering a quicker and easier installation compared to cat-back systems. While they may not provide significant performance gains, they can still make a noticeable difference in the exhaust note. If you're mainly looking to enhance the sound of your 2019 Audi S5 Sportback without breaking the bank, an axle-back system is a great choice.
• Downpipes: The downpipe connects directly to the turbocharger and plays a critical role in exhaust flow. Upgrading the downpipe can significantly reduce backpressure, leading to substantial gains in horsepower and torque. However, it's important to note that replacing the downpipe may require modifications to the ECU (Engine Control Unit) to optimize performance and avoid potential issues. Additionally, some downpipes may eliminate the catalytic converter, which could affect emissions compliance. If you're serious about maximizing performance and are willing to invest in additional modifications, a downpipe upgrade can be a game-changer.
• Full Exhaust Systems: A full exhaust system, also known as a turbo-back system, replaces the entire exhaust system from the turbocharger to the exhaust tips. This includes the downpipe, mid-pipe, muffler, and exhaust tips. Full exhaust systems offer the most comprehensive performance gains and the most significant improvement in sound. They are designed to optimize exhaust flow throughout the entire system, resulting in maximum horsepower and torque gains. However, full exhaust systems are typically the most expensive option and may require professional installation. If you're looking for the ultimate exhaust upgrade for your 2019 Audi S5 Sportback and are willing to invest the time and money, a full exhaust system is the way to go.
• Muffler Delete: For those seeking an aggressive and loud exhaust note on their 2019 Audi S5 Sportback, a muffler delete is an option. By removing the muffler, the exhaust gases flow directly out of the exhaust pipe, creating a raw and unfiltered sound. This modification is relatively inexpensive but can significantly increase the volume of your exhaust. However, it's important to be aware that a muffler delete may not be legal in all areas due to noise regulations. Additionally, it can result in a loss of backpressure, which could potentially affect performance. If you're considering a muffler delete, be sure to research local laws and regulations and weigh the potential pros and cons.
