The Subaru WRX is a beloved performance car that combines rally-inspired engineering with everyday usability. One of the most popular modifications among WRX enthusiasts is upgrading the exhaust system. In this article, we will review two of the top performance exhaust options for the Subaru WRX: the Perrin and Cobb exhaust systems. We will explore their sound, performance, and overall value, helping you make an informed decision for your vehicle.
Overview of Performance Exhaust Systems
Performance exhaust systems are designed to enhance the flow of exhaust gases from the engine, resulting in improved horsepower, torque, and overall engine efficiency. Additionally, these systems often provide a more aggressive sound that appeals to performance enthusiasts. When choosing an exhaust system for your Subaru WRX, it’s essential to consider both performance gains and sound characteristics.
Perrin Performance Exhaust
The Perrin Performance Exhaust is a well-regarded option among WRX owners. Known for its high-quality construction and performance benefits, Perrin has become a trusted name in the aftermarket community.
Sound Characteristics
The Perrin exhaust system is designed to produce a deep, aggressive tone that enhances the WRX’s sporty character. The sound is more pronounced at higher RPMs while remaining relatively tame at idle and cruising speeds, making it suitable for daily driving.
Performance Benefits
In terms of performance, the Perrin exhaust system is engineered to reduce back pressure, allowing for better exhaust flow. This results in noticeable gains in horsepower and torque, particularly in the mid to upper RPM range. Many users report improved throttle response and overall engine performance.
Installation and Fitment
The installation process for the Perrin exhaust is straightforward, with a bolt-on design that typically requires no cutting or welding. Most users can complete the installation with basic hand tools, making it accessible for DIY enthusiasts.
Cobb Performance Exhaust
Cobb Tuning is another highly respected name in the performance aftermarket, and their exhaust system for the Subaru WRX is no exception. Known for its quality and performance, the Cobb exhaust offers an appealing alternative to the Perrin system.
Sound Characteristics
The Cobb exhaust system produces a more refined sound compared to Perrin. It delivers a sporty growl that is more noticeable at wide-open throttle while maintaining a comfortable sound level during regular driving. This makes it an excellent choice for those who want a balance between performance and daily drivability.
Performance Benefits
The Cobb exhaust system is designed to optimize exhaust flow, resulting in significant performance improvements. Users often report increased horsepower and torque, particularly in the low to mid RPM range. The improved flow can lead to better fuel efficiency as well.
Installation and Fitment
Similar to the Perrin system, the Cobb exhaust is designed for easy installation. It features a bolt-on design that allows for quick and hassle-free setup. Most owners can install the system without professional help, making it a popular choice for DIY projects.
Comparison of Perrin and Cobb Exhausts
To help you decide between the Perrin and Cobb exhaust systems, let’s compare their key features:
- Sound: Perrin offers a deeper, more aggressive tone, while Cobb provides a refined growl.
- Performance: Both systems deliver significant horsepower and torque gains, but the Perrin is noted for mid to upper RPM improvements, while Cobb excels in low to mid RPM.
- Installation: Both systems feature a bolt-on design for easy installation.
- Build Quality: Both brands are known for high-quality materials and construction.
Conclusion
Choosing the right performance exhaust for your Subaru WRX ultimately comes down to personal preference. If you prefer a more aggressive sound and focus on mid to upper RPM performance, the Perrin exhaust may be the better choice for you. On the other hand, if you want a refined sound with strong low to mid-range performance, the Cobb exhaust is an excellent option. Either way, upgrading your exhaust will enhance your driving experience and unleash the full potential of your Subaru WRX.
