How to Achieve 50 Hp More on Your Scion Fr-s: Best Intake and Exhaust Upgrades

by

The Scion FR-S is a beloved sports car known for its balance, lightweight design, and engaging driving experience. However, many enthusiasts seek to unlock even more performance from this already impressive vehicle. If you’re looking to achieve an additional 50 horsepower, the best place to start is with intake and exhaust upgrades. This article will guide you through the most effective options available.

Understanding the Basics of Intake and Exhaust Systems

Before diving into specific upgrades, it’s important to understand how the intake and exhaust systems work together to influence engine performance. The intake system brings air into the engine, while the exhaust system expels gases after combustion. Enhancing both systems can lead to significant power gains.

Best Intake Upgrades for the Scion FR-S

Improving airflow into the engine is crucial for increasing horsepower. Here are some of the best intake upgrades for the Scion FR-S:

  • Cold Air Intake Systems: These systems draw cooler air from outside the engine bay, which is denser and can lead to better combustion.
  • Short Ram Intakes: These are designed to reduce the distance air has to travel to reach the engine, improving throttle response.
  • High-Performance Air Filters: Upgrading to a high-flow air filter can help increase airflow without needing to replace the entire intake system.

Several brands offer excellent cold air intake systems specifically for the Scion FR-S. Here are a few top contenders:

  • AEM Cold Air Intake: Known for its quality and performance, this intake can add significant horsepower and torque.
  • K&N 69 Series Typhoon: This system features a washable filter and is designed for maximum airflow.
  • Injen SP Series: This intake is engineered for optimal performance and features a unique design that enhances airflow.

Best Exhaust Upgrades for the Scion FR-S

After optimizing the intake, the next step is to enhance the exhaust system. A free-flowing exhaust can help expel gases more efficiently, leading to improved performance. Here are some of the best exhaust upgrades:

  • Cat-Back Exhaust Systems: These systems replace the exhaust from the catalytic converter back, improving flow and sound.
  • High-Performance Headers: Upgrading to aftermarket headers can reduce back pressure and improve exhaust flow.
  • Performance Mufflers: A high-flow muffler can enhance exhaust flow while providing a more aggressive sound.

Choosing the right cat-back exhaust system is crucial for achieving the desired performance and sound. Here are some popular options:

  • Greddy SP Elite: This system is known for its deep tone and significant performance gains.
  • HKS Legamax: Offers a perfect balance of sound and performance, making it a favorite among enthusiasts.
  • Borla ATAK: Known for its aggressive sound and performance, this exhaust is a great choice for those looking to stand out.

Combining Intake and Exhaust Upgrades

While upgrading either the intake or exhaust can lead to performance gains, combining both can maximize horsepower. When both systems are optimized, the engine can breathe more freely, leading to better performance overall.

Tuning Your Scion FR-S

After installing intake and exhaust upgrades, tuning your vehicle is essential to fully realize the potential gains. A proper tune adjusts the engine’s fuel maps and timing to accommodate the increased airflow. Here are some tuning options:

  • ECU Reflash: A reflash modifies the factory settings to optimize performance with the new upgrades.
  • Standalone Engine Management: For those looking for maximum control, a standalone system allows for extensive tuning options.
  • Piggyback Systems: These systems work alongside the factory ECU to improve performance without completely replacing it.

Conclusion

Achieving an additional 50 horsepower from your Scion FR-S is possible with the right intake and exhaust upgrades. By understanding how these systems work and selecting the best components, you can significantly enhance your vehicle’s performance. Don’t forget to tune your engine after making upgrades to ensure optimal performance and efficiency. With the right modifications, your Scion FR-S will not only be more powerful but also more enjoyable to drive.
