The Subaru BRZ has gained a reputation for being a fun, lightweight sports car that offers an engaging driving experience. However, many enthusiasts are always looking for ways to enhance performance. One popular modification is upgrading the exhaust system. In this article, we will explore the power gains achieved with the PRL Motorsports exhaust system on the Subaru BRZ, presenting real-world results that showcase the benefits of this modification.
Understanding the Subaru BRZ
The Subaru BRZ is a compact sports car developed in collaboration with Toyota, sharing its platform with the Toyota 86. Known for its rear-wheel-drive layout and balanced handling, the BRZ is powered by a naturally aspirated 2.4-liter flat-four engine. While it offers a thrilling driving experience, many owners seek ways to unlock additional power and improve exhaust flow.
The Importance of an Exhaust System
The exhaust system plays a crucial role in a vehicle’s performance. It is responsible for expelling exhaust gases from the engine, and a well-designed exhaust system can improve airflow, reduce back pressure, and enhance engine efficiency. Upgrading to a performance exhaust system can lead to noticeable power gains, improved throttle response, and a more aggressive sound.
Introducing PRL Motorsports Exhaust System
PRL Motorsports is known for producing high-quality performance parts for various vehicles, including the Subaru BRZ. Their exhaust system is designed to maximize airflow while maintaining a deep, aggressive tone. The system features mandrel-bent piping, high-flow catalytic converters, and a straight-through design to minimize restrictions.
Real-World Testing and Results
To evaluate the performance gains from the PRL Motorsports exhaust system, a series of tests were conducted on a stock Subaru BRZ. The testing involved measuring horsepower and torque before and after the installation of the exhaust system, using a dynamometer to ensure accurate results.
Baseline Measurements
Before the installation of the PRL exhaust system, the stock Subaru BRZ was tested, yielding the following results:
- Horsepower: 205 hp at 7,000 RPM
- Torque: 156 lb-ft at 4,000 RPM
Post-Installation Measurements
After installing the PRL Motorsports exhaust system, the same testing procedures were performed. The results showed a significant improvement:
- Horsepower: 220 hp at 7,200 RPM
- Torque: 165 lb-ft at 4,200 RPM
Power Gains Analysis
The results indicate a power gain of 15 horsepower and 9 lb-ft of torque after the installation of the PRL Motorsports exhaust system. This improvement enhances the overall performance of the BRZ, providing a more exhilarating driving experience.
Additional Benefits of the PRL Exhaust System
In addition to the power gains, there are several other benefits associated with upgrading to the PRL Motorsports exhaust system:
- Weight Reduction: The PRL exhaust system is lighter than the stock system, contributing to an overall weight reduction of the vehicle.
- Improved Sound: The exhaust produces a deeper, more aggressive sound that enhances the driving experience.
- Enhanced Aesthetics: The polished finish and design of the PRL exhaust system add a sporty look to the rear of the vehicle.
Conclusion
Upgrading to the PRL Motorsports exhaust system is a worthwhile investment for Subaru BRZ owners looking to enhance their vehicle’s performance. The real-world results demonstrate significant power gains, improved sound, and additional benefits that contribute to a more enjoyable driving experience. Whether you’re a casual driver or a motorsport enthusiast, this exhaust system is sure to elevate your BRZ to new heights.
