AWE Exhaust For BMW G20/G22 M340i & M440i: Review & Upgrade

So, you're thinking about upgrading the exhaust on your BMW G2x M340i or M440i? Smart move! An aftermarket exhaust system can seriously transform your driving experience, not just in terms of sound, but also performance. One name that often comes up in the BMW tuning world is AWE Tuning, and for good reason. Their exhaust suite for the G2x platform is pretty impressive. Let's dive into what makes the AWE exhaust a popular choice for BMW enthusiasts.

Why Upgrade Your Exhaust?

Before we get into the specifics of the AWE system, let's quickly cover why you might want to upgrade your exhaust in the first place. The factory exhaust on the M340i and M440i is decent, sure, but it's designed with mass-market appeal in mind. That means compromises in sound and performance to keep things quiet and meet emissions regulations. Aftermarket exhausts, on the other hand, are engineered for a more aggressive sound, improved exhaust flow, and, potentially, a bit of extra horsepower and torque. It’s all about unlocking the true potential of your B58 engine!

Think of the stock exhaust as a well-mannered guest at a party – it's polite and doesn't cause a ruckus. An AWE exhaust, however, is like the life of the party – loud, exciting, and impossible to ignore. If you're looking to turn heads and make a statement, an exhaust upgrade is definitely the way to go. Plus, the improved exhaust flow can help your engine breathe easier, leading to better throttle response and overall performance. It's a win-win!

Beyond just sound and performance, an aftermarket exhaust can also enhance the look of your car. AWE offers various tip options, from classic chrome to aggressive black diamond finishes, allowing you to customize the appearance of your rear end. Let's be honest; who doesn't want their car to look as good as it sounds? Upgrading your exhaust is an investment in both the performance and aesthetics of your BMW, making it a truly personalized driving machine.

AWE Exhaust Options for the G2x

AWE Tuning offers several exhaust configurations for the BMW G2x M340i and M440i, allowing you to choose the system that best suits your needs and preferences. Their offerings typically include:

• Cat-back systems: These replace the exhaust system from the catalytic converters back, offering a good balance of performance and sound without requiring any modifications to the downpipe.
• Axle-back systems: These are a more budget-friendly option, replacing only the rear section of the exhaust. While they may not offer the same performance gains as a cat-back system, they can still significantly improve the exhaust note.
• Downpipes: For those seeking maximum performance, AWE also offers downpipes. These replace the factory downpipe, which is typically the most restrictive part of the exhaust system. However, keep in mind that replacing the downpipe may affect emissions compliance and could require additional tuning.

Within each of these categories, AWE usually provides different sound level options. Their Touring Edition is designed for a refined, sporty sound, while their Track Edition is for those who want the loudest and most aggressive exhaust note possible. They also offer resonated and non-resonated versions. Resonated versions include resonators to help reduce drone, while non-resonated versions are generally louder and more raw. Selecting the correct version depends heavily on one's tolerance and personal preference. For those looking for the best of both worlds, valved systems are also an option; these allow you to control the exhaust volume with the push of a button.

Key Features of the AWE Exhaust

So, what exactly makes the AWE exhaust stand out from the competition? Here are some key features that contribute to its popularity:

• Precision Engineering: AWE exhausts are known for their precise fitment and high-quality construction. They use CNC machined flanges, mandrel-bent tubing, and TIG welding to ensure optimal performance and durability. This attention to detail translates to a product that not only performs well but also looks great under your car.
• Sound Engineering: AWE invests a lot of time and effort in developing the sound of their exhausts. They use sophisticated acoustic testing equipment to fine-tune the exhaust note and minimize drone. The result is an exhaust that sounds aggressive and sporty without being obnoxious or tiring on long drives.
• Performance Gains: While sound is a major factor for many enthusiasts, AWE exhausts are also designed to improve performance. By optimizing exhaust flow, they can help your engine breathe easier, leading to increased horsepower and torque. The exact gains will vary depending on the specific system and your car's modifications, but you can typically expect to see a noticeable improvement.
• Tip Options: AWE offers a variety of tip options to customize the look of your exhaust. Whether you prefer a classic chrome finish or a more aggressive black diamond look, you can choose the tips that best complement your car's style. This allows you to personalize your exhaust system and make it truly your own.
• Drone Mitigation: Exhaust drone can be a major annoyance, especially on long drives. AWE exhausts are designed with drone mitigation in mind, using resonators and other techniques to minimize unwanted frequencies. This ensures that your exhaust sounds great without being intrusive or irritating.

Installation and Fitment

Installing an AWE exhaust is generally straightforward, but it's always recommended to have it done by a qualified technician. The exact installation process will vary depending on the specific system, but it typically involves removing the factory exhaust and bolting on the AWE system in its place. AWE provides detailed instructions and all necessary hardware to ensure a smooth installation. Fitment is typically excellent, thanks to AWE's precise engineering and manufacturing processes.

However, like with any aftermarket modification, it's important to double-check that the exhaust system is compatible with your specific model year and configuration. Some minor adjustments may be necessary, depending on your car's modifications. For example, if you have aftermarket downpipes, you may need to modify the exhaust system to ensure proper fitment. Always consult with a qualified technician to ensure that the installation is done correctly and safely. Also, make sure you are following local laws by checking noise regulations in your area.

Sound and Performance Impressions

Okay, so the AWE exhaust looks good on paper, but how does it actually sound and perform in the real world? Well, the general consensus is that it sounds fantastic. The exhaust note is aggressive and sporty, with a deep growl at low RPMs and a high-pitched scream at high RPMs. It's definitely an upgrade over the factory exhaust, without being overly loud or obnoxious.

In terms of performance, many users report noticeable improvements in throttle response and overall power. The engine feels more responsive and eager to rev, making the car more fun to drive. While the exact horsepower and torque gains will vary depending on your car's modifications, you can typically expect to see a noticeable improvement. Dyno tests have shown gains anywhere from 5-15 horsepower, depending on the exhaust configuration and other modifications.

Alternatives to the AWE Exhaust

While AWE is a popular choice, it's not the only option for upgrading your BMW's exhaust. Here are a few other brands to consider:

• Remus: Remus is another well-known exhaust manufacturer that offers high-quality systems for the G2x platform. Their exhausts are known for their refined sound and excellent fitment.
• Akrapovic: Akrapovic is a premium exhaust manufacturer that specializes in high-performance systems. Their exhausts are typically made from titanium and offer exceptional performance and sound.
• Eisenmann: Eisenmann is a German exhaust manufacturer that has been producing high-quality exhausts for decades. Their exhausts are known for their aggressive sound and excellent craftsmanship.

Each of these brands has its own unique sound and performance characteristics, so it's worth doing some research to find the system that best suits your needs and preferences. Listen to sound clips, read reviews, and talk to other BMW enthusiasts to get a better sense of what each brand has to offer.
