Hey Crosstrek enthusiasts! Are you looking to upgrade your 2020 Subaru Crosstrek exhaust? Or maybe you're dealing with a repair and need to understand your options? You've come to the right place! In this comprehensive guide, we'll dive deep into everything you need to know about the 2020 Crosstrek exhaust system. From understanding the stock setup to exploring aftermarket upgrades and troubleshooting common issues, we've got you covered.

Understanding the Stock 2020 Subaru Crosstrek Exhaust System

Let's start with the basics. The stock exhaust system on your 2020 Subaru Crosstrek is designed for a balance of fuel efficiency, low emissions, and noise reduction. It's a pretty standard setup, consisting of several key components working together to channel exhaust gases away from the engine and out the back of the vehicle.

  • Exhaust Manifold: This is where it all begins. The exhaust manifold collects exhaust gases from each cylinder of the engine and directs them into a single pipe.
  • Catalytic Converter: A crucial component for emissions control, the catalytic converter uses chemical reactions to reduce harmful pollutants in the exhaust gases, such as hydrocarbons, carbon monoxide, and nitrogen oxides.
  • Resonator: The resonator helps to reduce noise and drone in the exhaust system. It's essentially a tuned chamber that cancels out certain frequencies.
  • Muffler: The final stage in noise reduction, the muffler uses baffles and sound-absorbing materials to quiet the exhaust gases before they exit the vehicle.
  • Piping: Connecting all these components are various lengths of exhaust piping, typically made of steel. These pipes are responsible for carrying the exhaust gases from one component to the next.

The stock exhaust system is perfectly adequate for most drivers and daily driving conditions. However, some owners may find it lacking in terms of performance or sound. This is where aftermarket upgrades come into play.

Aftermarket Exhaust Upgrades for Your 2020 Crosstrek

If you're looking to boost your Crosstrek's performance, enhance its sound, or simply give it a more aggressive look, an aftermarket exhaust upgrade might be just what you need. There are several options available, each offering different benefits and characteristics.

  • Cat-Back Exhaust Systems: A popular choice for many Crosstrek owners, cat-back systems replace everything from the catalytic converter back to the tailpipe. They typically offer improved exhaust flow, resulting in a slight increase in horsepower and torque. Cat-back systems also tend to produce a more aggressive exhaust note compared to the stock system.

    • Benefits: Improved exhaust flow, increased horsepower and torque (modest gains), enhanced exhaust sound, typically easy to install.
    • Considerations: Can be more expensive than axle-back systems, may require minor modifications for a perfect fit.

  • Axle-Back Exhaust Systems: Axle-back systems are a more budget-friendly option, replacing only the components from the rear axle back to the tailpipe. This usually includes the muffler and exhaust tips. Axle-back systems primarily focus on improving the exhaust sound and appearance, with minimal impact on performance.

    • Benefits: More affordable than cat-back systems, easy to install, noticeable improvement in exhaust sound, cosmetic upgrades with different exhaust tip styles.
    • Considerations: Minimal performance gains, may not offer the same level of sound enhancement as cat-back systems.

  • Exhaust Headers: For more serious performance enthusiasts, upgrading the exhaust headers can yield significant gains. Headers replace the stock exhaust manifold with a more efficient design that allows for better exhaust flow from the engine. However, header upgrades are more complex and may require professional installation.

    • Benefits: Significant improvement in exhaust flow, potential for substantial horsepower and torque gains.
    • Considerations: More expensive and complex to install, may require modifications to the exhaust system, may affect emissions compliance.

  • Muffler Delete: Muffler deletes are a cost-effective way to significantly increase the exhaust volume of your 2020 Subaru Crosstrek exhaust. While this method may give your car a more aggressive sound, it typically does not provide any performance benefits. Additionally, removing the muffler may not be legal in all areas due to noise regulations. Check local laws before opting for this modification.

When choosing an aftermarket exhaust system, it's important to consider your budget, desired performance gains, and sound preferences. Read reviews, watch videos, and talk to other Crosstrek owners to get a better understanding of the different options available.
