So, you're looking to upgrade the exhaust on your 2020 BMW M4 Competition? Great choice, guys! The M4 Competition is already a beast, but a new exhaust system can really take it to the next level, enhancing the sound, performance, and overall driving experience. Let's dive into everything you need to know about choosing the perfect exhaust for your ride.

Why Upgrade Your M4 Competition Exhaust?

Before we get into specific options, let's talk about why upgrading your exhaust is such a popular modification. The stock exhaust on the M4 Competition is decent, but it's often criticized for being too quiet, especially considering the car's aggressive styling and potent engine. An aftermarket exhaust can address this in a few key ways:

• Enhanced Sound: This is the most obvious benefit. A new exhaust can give your M4 a deeper, more aggressive growl, a louder roar, or a more refined and exotic tone, depending on the system you choose. Imagine cruising down the street and turning heads with that perfect exhaust note!
• Improved Performance: Many aftermarket exhausts are designed to be less restrictive than the factory system. This allows the engine to breathe more freely, which can result in increased horsepower and torque. While the gains might not be massive, they can definitely be noticeable, especially when combined with other modifications.
• Weight Reduction: Some aftermarket exhausts are made from lighter materials like titanium, which can reduce the overall weight of the car. This can improve handling and acceleration, making your M4 even more nimble and responsive.
• Aesthetics: Let's be honest, a shiny new exhaust system just looks cool. Many aftermarket options feature polished tips and aggressive designs that can enhance the visual appeal of your M4's rear end. It's all about that curb appeal, right?

Types of Exhaust Systems

Now that you know why you might want to upgrade, let's look at the different types of exhaust systems available for your 2020 M4 Competition:

• Axle-Back Exhaust: This is the simplest and most affordable option. It replaces the exhaust components from the rear axle back, typically including the mufflers and exhaust tips. Axle-back systems primarily focus on improving sound and aesthetics, with minimal performance gains.
• Cat-Back Exhaust: A cat-back system replaces the exhaust components from the catalytic converters back. This includes the mid-pipes, mufflers, and exhaust tips. Cat-back systems offer a better balance of sound, performance, and price compared to axle-back systems.
• Downpipes: Downpipes connect directly to the turbochargers and replace the factory downpipes, which contain catalytic converters. Upgrading to aftermarket downpipes can significantly improve exhaust flow and result in substantial performance gains. However, keep in mind that removing or replacing catalytic converters may be illegal in some areas and can affect emissions.
• Full Exhaust System: This is the most comprehensive and expensive option. A full exhaust system replaces all the exhaust components from the turbochargers back, including the downpipes, mid-pipes, mufflers, and exhaust tips. Full systems offer the greatest potential for performance gains and sound improvement.

Factors to Consider When Choosing an Exhaust

With so many options available, it's important to consider your individual needs and preferences when choosing an exhaust. Here are some key factors to keep in mind:

• Sound: What kind of sound are you looking for? Do you want a deep, aggressive growl, a loud, attention-grabbing roar, or a more refined and exotic tone? Listen to sound clips of different exhausts online to get an idea of what they sound like.
• Performance: Are you primarily interested in improving performance, or are you more focused on sound and aesthetics? If performance is your priority, look for exhausts that are designed to be less restrictive and improve exhaust flow.
• Budget: Exhaust systems can range in price from a few hundred dollars to several thousand dollars. Determine your budget before you start shopping so you can narrow down your options.
• Installation: Are you planning to install the exhaust yourself, or will you be taking it to a professional? Some exhausts are easier to install than others. Factor in the cost of installation if you're not planning to do it yourself.
• Legality: Be sure to check the local laws and regulations regarding exhaust modifications. Some areas have restrictions on noise levels or require catalytic converters to be in place. You don't want to get a ticket, do you?

Installation Tips

If you're planning to install your new exhaust yourself, here are a few tips to make the process go smoothly:

• Gather the Necessary Tools: Make sure you have all the tools you need before you start, including a socket set, wrenches, a torque wrench, and penetrating oil.
• Raise the Car Safely: Use a jack and jack stands to safely raise the car off the ground. Never work under a car that is only supported by a jack.
• Spray Penetrating Oil: Spray penetrating oil on the exhaust bolts to loosen them up before you try to remove them.
• Follow the Instructions: Carefully follow the instructions that come with your new exhaust system. Seriously, read the manual!
• Torque to Spec: Use a torque wrench to tighten the exhaust bolts to the manufacturer's specifications.

Maintaining Your New Exhaust

Once you've installed your new exhaust, it's important to maintain it properly to keep it looking and sounding its best. Here are a few tips:

• Regular Cleaning: Clean your exhaust tips regularly with a metal polish to remove dirt and grime.
• Inspect for Leaks: Check for exhaust leaks periodically. Leaks can reduce performance and cause the exhaust to sound raspy.
• Avoid Harsh Chemicals: Avoid using harsh chemicals or abrasive cleaners on your exhaust, as they can damage the finish.
