Hey guys, let's dive into the awesome world of the 2020 BMW M4 Competition and, more specifically, its exhaust system! If you're lucky enough to own one of these beauties, or even if you're just dreaming about it, you know that the M4 Competition is all about performance and that incredible driving experience. A big part of that experience is, of course, the sound. The exhaust system plays a massive role in both the performance and the auditory symphony that your M4 creates. So, let's explore the exhaust options, the benefits of upgrading, and how to get that perfect roar. We will cover the stock exhaust, aftermarket upgrades, and what to consider when choosing the right exhaust system for your 2020 BMW M4 Competition.

Stock Exhaust System: What's the Deal?

Before we jump into the exciting world of aftermarket exhausts, let's take a look at what the 2020 BMW M4 Competition comes with from the factory. The stock exhaust is designed to balance performance, sound, and emissions regulations. This means it's a bit of a compromise. BMW engineers do a great job, but there are always restrictions. They have to meet noise levels, and that often means the stock exhaust is a little too quiet for the enthusiasts among us. The stock system is typically made from stainless steel and features a catalytic converter, resonators, and mufflers. These components work together to filter the exhaust gases and keep the sound levels in check. But, in doing so, they can also restrict the flow of exhaust gases, which can slightly limit the engine's power potential. The sound is decent, it is a nice growl, and it has the typical BMW character, but it's not going to turn heads like an aftermarket system will. Therefore, the goal of those who are upgrading the exhaust system is to have more power and sound.

The stock exhaust is built to be durable and reliable, it's designed to last, but it may not offer the aggressive sound and the performance gains that many M4 Competition owners are looking for. So, while it does its job well, it leaves some room for improvement, and that is where aftermarket exhausts come into play. It is important to remember that it is not a bad exhaust; it is just a bit restricted, and for many owners, this is simply not enough. BMW designed the M4 Competition to be a high-performance machine, and the stock exhaust, while good, doesn't always fully unleash the potential of that engine. Therefore, if you are planning to upgrade it, you should know that you are in for a big improvement in both sound and performance.

Why Upgrade Your 2020 BMW M4 Competition Exhaust?

So, why would you even consider upgrading the exhaust on your 2020 BMW M4 Competition? Well, there are several key benefits that make it a worthwhile modification. First and foremost, a properly designed aftermarket exhaust system can significantly improve the sound. The stock exhaust is often muted to meet regulations, but an upgraded system can unleash the full potential of that incredible engine. You will enjoy a more aggressive, deeper, and more exhilarating exhaust note that perfectly complements the M4's high-performance character. When driving, this makes the entire experience so much more enjoyable, making every acceleration a moment to remember. For some, the sound itself is a significant factor, a primary reason for making the upgrade. The right exhaust system can transform the way the car sounds, making it a true head-turner.

Beyond the amazing sound, upgrading your exhaust can also boost performance. By reducing backpressure and improving exhaust flow, aftermarket systems can free up some extra horsepower and torque. This might not be a huge jump, but every bit helps, right? The engine will breathe more freely, which means it can generate more power more efficiently. Depending on the system, you could see gains in both horsepower and torque, especially in the mid-range, which makes for better acceleration and responsiveness. These gains often translate into quicker lap times on the track or simply more exhilarating performance on the street. It is the type of upgrade that you can feel when you hit the gas. This is not just about sound; it's about making your M4 Competition even more of a beast.

Also, you can reduce weight. Many aftermarket exhausts are made from lighter materials, such as titanium or high-grade stainless steel. This can help to reduce the overall weight of the car, which in turn can improve handling and acceleration. The lighter the car, the better it is, right? This seemingly small reduction in weight can have a positive impact on overall performance, especially when cornering. Even if the weight reduction is not huge, every pound counts, and a lighter car feels more agile and responsive on the road and track. This is more of a side benefit, but it's still a nice bonus. By reducing backpressure and improving exhaust flow, aftermarket systems can also free up some extra horsepower and torque.

Aftermarket Exhaust Options for Your M4 Competition

Alright, now for the exciting part: What are your options when it comes to aftermarket exhausts for your 2020 BMW M4 Competition? There's a huge variety out there, and the best choice depends on your budget, your desired sound, and your performance goals. Here are some of the popular types of exhaust systems you can find:

• Cat-Back Exhaust Systems: This is one of the most common upgrades. These systems replace the exhaust components from the catalytic converters (or, more commonly, just after the catalytic converters) back to the exhaust tips. Cat-back systems offer a great balance of improved sound, performance, and ease of installation. They are often a good starting point for exhaust upgrades, as they provide a noticeable improvement without being overly complex or expensive. Many brands offer complete cat-back systems tailored specifically for the M4 Competition, so you'll find plenty of choices, and they are pretty easy to install, even at home.
• Axle-Back Exhaust Systems: This is a more basic upgrade that replaces the exhaust components from the rear axle back to the exhaust tips. Axle-back systems are usually the most affordable option and offer a simple way to improve the sound. While they may not provide as much of a performance gain as a cat-back system, they are still a good way to give your M4 a more aggressive exhaust note. They are the easiest to install, typically just bolting right on. This makes them a popular choice for those looking for a quick and easy upgrade.
• Downpipes: This is where things get serious. Downpipes replace the factory pipes that connect the exhaust manifolds to the catalytic converters. Upgrading your downpipes, especially with catless or high-flow catalytic converters, can significantly improve exhaust flow and boost power. However, be aware that catless downpipes are often not street-legal and can trigger check engine lights. High-flow cats offer a good compromise between performance and compliance. This modification requires more technical expertise to install and may involve additional tuning, but the performance gains can be substantial.
• Full Exhaust Systems: As you might guess, a full exhaust system replaces all the components from the exhaust manifolds all the way back to the tips. This is the most comprehensive upgrade and offers the greatest potential for performance gains. This usually includes headers, downpipes, cat-back systems, and often resonators and mufflers. Full systems are typically the most expensive and require the most complex installation. You'll likely need professional installation and may need to retune your engine to maximize the benefits.

Each of these options has its own pros and cons, but the cat-back systems are often a good starting point for exhaust upgrades as they provide a noticeable improvement without being overly complex or expensive.

Materials and Construction

The materials used to make the exhaust system will influence durability, performance, and of course, the price. Here are the most common materials:

• Stainless Steel: It's the most common material because it is a great balance of cost, durability, and performance. It's rust-resistant and can withstand high temperatures, making it a reliable choice for exhaust systems. Stainless steel exhausts offer good value and are often a popular choice for all types of exhaust systems. You can expect years of service from it.
• Titanium: This is the premium option. Titanium is incredibly strong and lightweight, offering superior performance and a unique, high-pitched sound. It's also resistant to corrosion. Titanium exhaust systems are more expensive but are often preferred by performance enthusiasts who want the best of the best. The weight savings are also a huge bonus, and the sound is unmistakable.
• Aluminum: This is also a premium material; aluminum exhaust systems are not as common. They are lightweight and offer good corrosion resistance, but they are generally less durable than stainless steel or titanium. Aluminum is still a viable option for weight savings and performance, but they are typically for specific applications.

Installation and Considerations

When choosing an exhaust system, it's essential to consider the installation process. Some systems are designed for easy bolt-on installation, while others may require welding or professional installation. If you are not comfortable working on your car, it is a good idea to seek professional help. Professional installation ensures that the system is installed correctly and that you get the best performance and sound possible. The difficulty of installation can vary significantly depending on the type of exhaust system and the complexity of your vehicle. The cat-back and axle-back systems are usually the easiest to install. Always make sure the system you choose is compatible with your 2020 BMW M4 Competition, and double-check all the measurements and fittings. Many manufacturers provide detailed instructions and videos to help with the installation, and you can always consult a professional if you need help.

Also, consider the following:

• Sound Level: How loud do you want your car to be? Some exhausts are designed for a more subtle upgrade, while others are incredibly aggressive. Make sure to check the sound clips and reviews before making your final decision. Consider your local noise regulations as well, as some aftermarket exhausts can be too loud for certain areas.
• Performance Goals: Do you want to maximize performance, or is the sound more important? Consider what gains you expect from your upgrade.
• Budget: Exhaust systems can range from a few hundred dollars to several thousand. Setting a budget beforehand will help you narrow down your options and avoid overspending.
• Legal Considerations: Are the exhaust modifications street-legal in your area? Some states have strict emissions laws that can restrict your options. Check your local regulations before making a purchase.

Maintaining Your Exhaust System

Once you have upgraded your exhaust, you'll want to take good care of it to ensure it lasts for years to come. Regularly inspect your exhaust system for any leaks, damage, or corrosion. Clean the exhaust tips to keep them looking their best. Also, if you live in an area with harsh winters or salted roads, consider protecting your exhaust system with a ceramic coating or sealant. This will help to prevent corrosion and keep your exhaust system looking good for the long haul. Regular maintenance is important to keep your exhaust system in top condition and ensure it delivers optimal performance and sound.
