The Subaru WRX is renowned for its performance and tuning potential, and one of the most impactful modifications enthusiasts can make is upgrading the exhaust system. Among the most popular options are the Borla, Remus, and Takeda turbo back exhaust systems. Each of these systems offers unique sound characteristics and performance benefits. In this article, we will conduct sound tests to compare these three exhaust systems, helping you make an informed decision for your WRX.
Understanding Turbo Back Exhaust Systems
A turbo back exhaust system replaces the entire exhaust path from the turbocharger to the rear of the vehicle. This upgrade can enhance power output, improve throttle response, and significantly alter the sound of your WRX. The choice of materials, design, and muffler type all contribute to the final sound and performance of the exhaust system.
Overview of Exhaust Systems
- Borla: Known for its high-quality construction and deep, aggressive sound.
- Remus: Offers a sporty tone with a focus on performance and refinement.
- Takeda: Aimed at maximizing airflow and producing a loud, attention-grabbing sound.
Sound Test Methodology
To accurately compare the sound of each exhaust system, we conducted a series of sound tests under controlled conditions. The tests included:
- Static revs at 2,000, 4,000, and 6,000 RPM.
- On-road sound tests during acceleration.
- Decibel measurements at various distances.
Borla Turbo Back Exhaust Sound Test
The Borla turbo back exhaust is known for its rich, deep tone. During our sound tests, it produced a strong growl at lower RPMs, transitioning to a refined roar at higher RPMs. The overall sound was aggressive yet not overwhelming, making it suitable for daily driving.
Static Revs
At 2,000 RPM, the Borla system emitted a deep, throaty rumble. At 4,000 RPM, the sound became more pronounced, with a noticeable increase in volume. By 6,000 RPM, the exhaust produced an exhilarating roar that showcased the engine’s power.
On-Road Performance
During on-road tests, the Borla system provided a satisfying sound during acceleration without excessive drone at cruising speeds. It struck a balance between performance and comfort, making it a popular choice among WRX enthusiasts.
Remus Turbo Back Exhaust Sound Test
The Remus turbo back exhaust system is designed to provide a sporty tone while maintaining a level of refinement. Our sound tests revealed that this system offers a unique blend of aggressiveness and sophistication.
Static Revs
At 2,000 RPM, the Remus system produced a subtle growl, which became more pronounced at 4,000 RPM with a crisp, aggressive note. By 6,000 RPM, the sound was exhilarating, showcasing the turbocharged engine’s capabilities with a distinctive edge.
On-Road Performance
On the road, the Remus system offered a refined experience. It provided a sporty sound during acceleration while minimizing drone at highway speeds. This makes it an excellent choice for those who want performance without sacrificing daily drivability.
Takeda Turbo Back Exhaust Sound Test
The Takeda turbo back exhaust is known for its loud and aggressive sound. Our sound tests indicated that this system is designed for those who want to make a statement with their WRX.
Static Revs
At 2,000 RPM, the Takeda system produced a loud, aggressive tone that was immediately noticeable. At 4,000 RPM, the sound intensified, and by 6,000 RPM, it reached a peak volume that was both thrilling and exhilarating.
On-Road Performance
During on-road tests, the Takeda system delivered an aggressive sound that turned heads. However, it did produce some drone at highway speeds, which may not be suitable for all drivers. This system is ideal for those who prioritize sound and presence over subtlety.
Comparative Analysis
After conducting sound tests on the Borla, Remus, and Takeda turbo back exhaust systems, we can summarize the findings as follows:
- Borla: Deep and aggressive sound, balanced for daily driving.
- Remus: Sporty and refined, ideal for performance without excessive noise.
- Takeda: Loud and attention-grabbing, perfect for those who want a bold presence.
Conclusion
Choosing the right turbo back exhaust system for your WRX ultimately depends on your personal preferences and driving style. The Borla system offers a well-rounded sound suitable for everyday use, while the Remus provides a refined sporty tone. For those seeking maximum volume and presence, the Takeda system stands out. Consider your priorities and take the time to listen to each system in person if possible, as sound is a highly subjective aspect of any performance modification.
