Hey guys! Let's dive deep into the world of the 2019 Audi S5 Sportback exhaust system. We're talking about everything from the factory setup to the best aftermarket upgrades that can seriously boost your car's performance, sound, and overall style. If you're an Audi S5 Sportback owner, you know that this car is already a stunner, offering a blend of luxury, performance, and practicality. But, are you ready to take it to the next level? The exhaust system is a fantastic place to start. A well-chosen exhaust system can significantly enhance your driving experience, providing more power, a throaty sound, and a head-turning aesthetic. So, buckle up, because we're about to explore the ins and outs of your exhaust options!

Understanding the Stock Exhaust System

Alright, first things first, let's talk about the stock exhaust. The 2019 Audi S5 Sportback comes equipped with a pretty decent factory exhaust system. It's designed to balance performance, sound, and emissions standards. This means it's generally quiet, efficient, and meets all the necessary regulations. However, if you're looking for more excitement, the factory exhaust might leave you wanting more. The stock system often prioritizes noise reduction, which can sometimes come at the expense of a richer, more aggressive sound and potentially a slight reduction in backpressure.

So, what's inside? Typically, you'll find a catalytic converter, a resonator, and mufflers. The catalytic converter is crucial for emissions control, while the resonator helps to reduce unwanted noise frequencies. The mufflers further quiet the exhaust note before it exits through the tailpipes. This setup is perfectly functional for everyday driving, but it doesn't always deliver the thrilling experience that enthusiasts crave. The materials used are generally durable but not necessarily optimized for performance gains. If you're happy with a quiet and efficient ride, the stock exhaust is perfectly fine. But, if you're like most S5 owners and want to unlock the full potential of your car, read on! You'll learn about the exciting possibilities of upgrading your exhaust system to get the most out of your ride. Now, let’s talk about those all-important exhaust upgrades!

Benefits of Upgrading Your Exhaust

Upgrading the exhaust on your 2019 Audi S5 Sportback offers a whole bunch of benefits that go beyond just a louder sound. Think of it as a complete performance package. One of the biggest advantages is an increase in horsepower and torque. By replacing restrictive components like the catalytic converter, resonator, and mufflers with high-flow parts, you're allowing the engine to breathe more freely. This reduction in backpressure can translate into noticeable gains in both power and torque, making your car feel peppier and more responsive. You'll likely experience quicker acceleration and improved throttle response, which is awesome for spirited driving and passing. Then there's the sound. An aftermarket exhaust system can transform the character of your S5, giving it a deeper, more aggressive growl that lets everyone know you mean business.

This isn't just about being loud; it's about the quality of the sound. Many aftermarket systems are designed to provide a rich, resonant tone that complements the Audi's engine without being overly obnoxious. Along with the performance and sound upgrades, there's also the aesthetic enhancement. Aftermarket exhaust systems often feature stylish tips and a more aggressive appearance, making your car look as good as it sounds. From polished stainless steel to carbon fiber, there are options to suit every taste. These visual upgrades can significantly enhance the car's overall appearance, giving it a more sporty and refined look.

Furthermore, upgrading your exhaust can improve fuel efficiency. While the gains aren't always huge, a more efficient exhaust system can help optimize engine performance, leading to slight improvements in fuel economy. Finally, a high-quality aftermarket exhaust system can increase your car's resale value. It's a desirable modification that appeals to many potential buyers, making your car more attractive in the used car market. The bottom line? Upgrading your exhaust is a win-win: improved performance, a better sound, and a more stylish car.

Popular Exhaust Upgrades for the 2019 Audi S5 Sportback

Alright, let's get into the nitty-gritty of exhaust upgrades. There's a wide variety of options available for your 2019 Audi S5 Sportback, each with its own set of pros and cons. We'll start with cat-back exhaust systems. Cat-back systems replace the exhaust components from the catalytic converter back, including the resonator and mufflers. They're a popular choice because they offer a significant improvement in sound and performance without requiring any modifications to the catalytic converter. They are also usually straightforward to install. You can expect a noticeable increase in horsepower, a deeper exhaust note, and often, more stylish exhaust tips.

Next up, we have downpipes. Downpipes are installed directly after the turbocharger and replace the factory downpipes, which often have restrictive catalytic converters. Upgrading to high-flow downpipes can significantly increase exhaust flow, leading to substantial gains in horsepower and torque. However, you should know that installing downpipes may require some extra work. They can sometimes trigger check engine lights if the car's ECU isn't properly tuned. They can also make your exhaust louder, so keep that in mind if you want to stay stealthy. Then, there are axle-back exhaust systems. Axle-back systems replace the mufflers and exhaust tips, offering a more budget-friendly upgrade.

They're easy to install and provide a noticeable improvement in sound and aesthetics. However, the performance gains are usually less significant compared to cat-back or downpipe systems. Lastly, let’s consider performance headers. Performance headers replace the exhaust manifolds, which are located directly on the engine. Headers are designed to optimize exhaust flow, leading to significant improvements in horsepower and torque. They're a more complex upgrade and often require professional installation, but the performance gains can be substantial. Keep in mind that different exhaust brands will cater to different preferences. Some brands focus on aggressive sound, while others prioritize a refined, sporty tone. Do your homework and read reviews to find the perfect exhaust system for your Audi.

Choosing the Right Exhaust System

Okay, so you're ready to pick out an exhaust system. How do you choose the right one for your 2019 Audi S5 Sportback? First things first: consider your goals. What do you want to achieve with the upgrade? Do you prioritize maximum performance, a specific sound, or a certain look? Do you want a subtle upgrade, or do you want to announce your arrival with a symphony of sound? Your answer to this question will influence your choices. Research different brands and read reviews. Reputable brands like AWE Tuning, Milltek, and Borla are well-known for their quality and performance. Read reviews from other Audi S5 Sportback owners to get a sense of each system's sound, performance, and ease of installation.

Don't hesitate to check out videos online. Seeing (and hearing) the exhaust in action can help you visualize how it will look and sound on your car. Consider the materials and construction quality. Look for systems made from high-quality stainless steel or titanium for durability and corrosion resistance. Think about the installation process. Some systems are designed for easy bolt-on installation, while others may require professional installation, especially for more complex upgrades like downpipes or headers. Be mindful of your budget. Exhaust systems range in price, so set a budget before you start shopping. Remember to factor in the cost of installation if you're not planning to do it yourself. Also, think about the local regulations regarding noise and emissions. Make sure your chosen system complies with local laws to avoid any issues. By carefully considering these factors, you can make an informed decision and choose the perfect exhaust system to enhance your 2019 Audi S5 Sportback.

Installation and Maintenance

Alright, you've chosen your exhaust system. Now, let's talk about installation and maintenance. If you're mechanically inclined, you might be able to install a cat-back or axle-back system yourself. These systems often come with clear instructions and are designed to be bolt-on replacements. However, if you're not comfortable working on your car, it's best to have a professional install the system. Professional installation ensures that the system is properly aligned and secured, preventing any leaks or other issues. For downpipes and headers, professional installation is generally recommended due to their complexity.

After installation, it's essential to monitor your exhaust system for any leaks or unusual noises. Check the exhaust tips regularly and clean them as needed. Keep an eye out for any signs of corrosion, especially if you live in an area with harsh weather conditions or road salt. If you notice any issues, such as a drop in performance or a change in sound, have the system inspected by a qualified mechanic. Regular maintenance will help keep your exhaust system in top condition and ensure that you continue to enjoy its benefits for years to come. In summary, if you choose to install yourself, follow the instructions carefully. If you have the pros do it, make sure they have experience with Audi vehicles. Lastly, regular checks and cleaning will make your exhaust last a long time.
