The FA20 engine, known for its balance of performance and efficiency, can benefit significantly from exhaust upgrades. With a budget of $1,000, enthusiasts can achieve up to a 20 horsepower increase. In this article, we will explore the best exhaust upgrades available for the FA20 engine, focusing on cost-effectiveness and performance gains.
Understanding the FA20 Engine
The FA20 is a 2.0-liter flat-four engine produced by Subaru. It is known for its unique boxer design, providing a lower center of gravity and improved handling characteristics. However, like many factory engines, it has room for improvement, particularly in the exhaust system.
Why Upgrade the Exhaust?
Upgrading the exhaust system can enhance engine performance by improving airflow, reducing back pressure, and increasing the overall efficiency of the engine. This can lead to noticeable gains in horsepower and torque, especially when combined with other modifications.
Top Exhaust Upgrades for the FA20
- Cat-Back Exhaust Systems: These systems replace the exhaust from the catalytic converter back, enhancing sound and performance.
- Downpipes: Upgrading to a high-flow downpipe can significantly reduce exhaust restrictions.
- Headers: Performance headers improve exhaust flow from the engine.
- Resonator Deletes: Removing the resonator can increase sound and reduce weight.
Best Cat-Back Exhaust Systems
Cat-back exhaust systems are among the most popular upgrades for the FA20. They offer a balance of sound, performance, and ease of installation. Here are some of the best options:
- Invidia Q300: Known for its deep tone and excellent fitment, the Q300 offers a subtle increase in power.
- Greddy Supreme SP: This system provides a sporty sound while maintaining a comfortable volume for daily driving.
- Nameless Performance: Offers a variety of options including muffler deletes for a more aggressive sound.
High-Flow Downpipes
Upgrading the downpipe can yield some of the most significant power gains for the FA20. A high-flow downpipe reduces back pressure and enhances turbo efficiency. Consider these options:
- Invidia Catted Downpipe: Balances performance with emissions compliance, offering a good increase in power.
- GrimmSpeed Downpipe: Designed for maximum flow, this option is a favorite among performance enthusiasts.
- COBB Tuning Downpipe: Known for its durability and performance, making it a reliable choice.
Performance Headers
Headers can significantly improve exhaust flow right from the engine. Here are some recommended headers for the FA20:
- J-Pipe Headers: These headers are designed to optimize exhaust flow and improve turbo response.
- Nameless Performance Headers: Known for their quality and performance, these headers can make a noticeable difference.
- Torque Solutions Headers: Offers a good balance of performance and price, making them a solid choice.
Resonator Deletes
For those looking to enhance sound without a significant investment, a resonator delete can be an effective modification. This simple change can make your exhaust note more aggressive.
- DIY Resonator Delete: Many enthusiasts choose to perform this modification themselves for cost savings.
- Shop Resonator Delete: Professional installation ensures proper fitment and performance.
Combining Upgrades for Maximum Gains
To achieve the best results, consider combining multiple upgrades. For example, pairing a high-flow downpipe with a cat-back exhaust system can maximize power gains and improve overall performance.
Budgeting for Exhaust Upgrades
Staying within a $1,000 budget is feasible with careful planning. Here’s a breakdown of potential costs:
- Cat-Back Exhaust: $500 – $800
- High-Flow Downpipe: $300 – $500
- Headers: $400 – $700
- Resonator Delete: $50 – $150
Conclusion
Upgrading the exhaust system of the FA20 engine is a cost-effective way to increase horsepower and enhance the driving experience. With careful selection of components and a focus on quality, achieving a 20 horsepower increase within a $1,000 budget is entirely possible. Whether you choose a cat-back system, downpipe, headers, or a combination of these upgrades, the benefits will be evident in both performance and sound.
