Nov 14, 2025 by Alex Braham 54 views

So, you're looking to upgrade the exhaust on your 2019 Audi S5 Sportback? Awesome choice, guys! The S5 is already a sweet ride, but a new exhaust system can seriously amplify its performance and sound, taking it to a whole new level. Let's dive into everything you need to know about S5 Sportback exhausts, from understanding the stock system to exploring aftermarket options and maximizing that glorious sound.

Understanding the Stock Exhaust System

Before we get into aftermarket upgrades, let's take a quick peek under the hood (or rather, under the chassis) and understand what's going on with the stock exhaust system in your 2019 Audi S5 Sportback. The factory exhaust is designed with a focus on balancing performance, sound, and emissions. It's built to be compliant and relatively quiet, which, let's be honest, leaves a lot to be desired if you're an enthusiast craving a more aggressive sound. The stock system typically consists of several key components:

Catalytic Converters: These are crucial for reducing harmful emissions, but they also restrict exhaust flow to some extent. They use catalysts to convert pollutants like hydrocarbons, carbon monoxide, and nitrogen oxides into less harmful substances.
Resonators: Resonators help to cancel out certain frequencies, reducing drone and unwanted noise inside the cabin. They are designed to create destructive interference, which minimizes specific sound frequencies that can cause discomfort during driving.
Mufflers: Mufflers are the primary sound-dampening components. They use a combination of chambers and baffling to reduce exhaust noise to an acceptable level for daily driving. The design of the muffler directly impacts the overall sound profile of the exhaust system.
Piping: The diameter and design of the exhaust piping influence exhaust flow and overall performance. Stock piping is usually optimized for efficiency and cost, which may limit potential gains compared to larger, mandrel-bent aftermarket options.

While the stock system does its job, it's often a compromise. Automakers have to consider a wide range of factors, including noise regulations, fuel efficiency, and overall comfort. This is why many S5 owners look to aftermarket exhausts to unlock the true potential of their vehicles. By upgrading the exhaust, you can often improve exhaust flow, reduce backpressure, and significantly enhance the sound, resulting in a more engaging and thrilling driving experience. So, if you're after a throatier growl and improved performance, exploring aftermarket options is definitely the way to go. Remember, choosing the right exhaust depends on your personal preferences and how you intend to use your S5 Sportback. Do you want a subtle improvement, or are you aiming for a head-turning roar? That will guide your decision-making process.

Why Upgrade Your S5 Sportback Exhaust?

Alright, so why even bother upgrading your 2019 Audi S5 Sportback's exhaust in the first place? Good question! There are several compelling reasons why enthusiasts like us swap out the factory system for something a bit more… spirited. Let's break down the main benefits:

Enhanced Sound: This is the big one for most people. The stock exhaust on the S5 is pretty tame. An aftermarket exhaust can transform the sound from a subtle hum to a glorious roar. You'll get a deeper, more aggressive tone that announces your presence without being obnoxious (unless that's what you're going for, of course!). The sound enhancement alone is often worth the upgrade for many enthusiasts.
Improved Performance: While the gains might not be earth-shattering, an aftermarket exhaust can definitely improve your S5's performance. Upgraded exhausts are typically designed with larger diameter piping and less restrictive mufflers, which allows exhaust gases to flow more freely. This reduces backpressure, which can lead to increased horsepower and torque, especially in the mid-range. You might notice a slight improvement in throttle response as well.
Weight Reduction: Believe it or not, some aftermarket exhausts are lighter than the factory system. This is especially true if you opt for a system made from materials like stainless steel or titanium. Reducing weight can improve handling and overall performance, making your S5 feel more nimble and responsive.
Aesthetic Appeal: Let's face it, a shiny new exhaust system just looks cool! Many aftermarket exhausts feature polished tips and sleek designs that can enhance the overall appearance of your S5 Sportback. It's a subtle touch that can make a big difference in the car's overall presence.
Personalization: Upgrading your exhaust is a great way to personalize your S5 and make it your own. With so many different brands and styles available, you can choose an exhaust that perfectly matches your taste and driving style. It's all about making your car a reflection of your personality.

Ultimately, upgrading your S5 Sportback's exhaust is about enhancing the overall driving experience. Whether you're after a more aggressive sound, improved performance, or just a more personalized look, a new exhaust can deliver. Just be sure to do your research and choose a system that's right for you!

Types of Aftermarket Exhaust Systems

Okay, so you're sold on the idea of upgrading your S5 Sportback's exhaust. Now comes the fun part: choosing the right system! But with so many options available, it can be a bit overwhelming. Let's break down the different types of aftermarket exhaust systems you'll typically encounter:

Cat-Back Systems: This is the most common type of exhaust upgrade. A cat-back system replaces everything from the catalytic converters back to the exhaust tips. It typically includes a mid-pipe, resonators (optional), mufflers, and exhaust tips. Cat-back systems offer a good balance of performance and sound improvement without requiring any modifications to the catalytic converters.
Axle-Back Systems: An axle-back system is a more budget-friendly option that replaces only the components from the rear axle back, typically just the mufflers and exhaust tips. Axle-back systems are easier to install and offer a modest improvement in sound. However, they generally don't provide as much of a performance gain as cat-back systems.
Downpipes: Downpipes connect directly to the turbocharger and replace the factory downpipe, which includes the catalytic converter. Upgrading the downpipe can significantly improve exhaust flow and boost performance. However, it's important to note that replacing the catalytic converter may not be legal in all areas, so be sure to check your local regulations before making this modification. Also, replacing the downpipe often requires a tune to optimize the engine for the increased flow.
Full Exhaust Systems: A full exhaust system replaces the entire exhaust system from the turbocharger all the way back to the exhaust tips. This is the most comprehensive upgrade and offers the greatest potential for performance gains. However, it's also the most expensive and complex to install, and may require modifications to the ECU.

When choosing an exhaust system, it's important to consider your goals and budget. Do you want maximum performance, or are you primarily interested in improving the sound? Are you comfortable with more extensive modifications, or do you prefer a simple bolt-on solution? Answering these questions will help you narrow down your options and choose the right exhaust system for your 2019 Audi S5 Sportback.

Sound Level: This is a big one! Do you want a subtle increase in sound, or are you looking for something that will turn heads? Consider where you typically drive and what kind of sound is appropriate for your daily commute. If you live in a quiet neighborhood, you might want to avoid overly loud exhausts. Listen to sound clips online to get a better idea of the exhaust's tone and volume.
Performance Goals: Are you primarily interested in improving the sound, or are you looking for a noticeable increase in horsepower and torque? If performance is your main goal, look for exhaust systems with larger diameter piping and less restrictive mufflers. Keep in mind that significant performance gains may require additional modifications, such as a tune.
Budget: Exhaust systems can range in price from a few hundred dollars to several thousand. Determine how much you're willing to spend before you start shopping. Keep in mind that the cost of installation can also add to the overall price.

Aluminized steel is more affordable but may not last as long. Titanium is the most expensive option but offers superior weight savings and corrosion resistance.
Installation: How comfortable are you with installing the exhaust yourself? Some exhaust systems are easier to install than others. If you're not mechanically inclined, you may want to have a professional install the exhaust for you. Consider the cost of installation when budgeting for your exhaust upgrade.
Local Regulations: Be sure to check your local laws and regulations regarding exhaust modifications. Some areas have restrictions on noise levels and catalytic converter removal. Make sure your chosen exhaust system complies with all applicable laws to avoid any potential issues.

By carefully considering these factors, you can narrow down your options and choose an exhaust system that perfectly matches your needs and preferences. Take your time, do your research, and don't be afraid to ask for advice from other S5 owners.

Installation Tips and Considerations

Okay, you've picked out your dream exhaust system. Now it's time to get it installed! Whether you're tackling the installation yourself or having a professional do it, here are a few tips and considerations to keep in mind:

Read the Instructions: This might seem obvious, but it's crucial! Carefully read the installation instructions that come with your exhaust system before you start. This will help you understand the process and avoid any potential mistakes.
