The GR Corolla has quickly become a favorite among car enthusiasts, known for its sporty performance and engaging driving experience. One of the most significant upgrades that owners consider is the exhaust system, which can dramatically change the car’s sound and character. In this article, we will conduct an exhaust sound test comparing two popular aftermarket options: the Fujitsubo and HKS exhaust systems.
Understanding Exhaust Systems
Before diving into the sound test, it’s essential to understand the role of an exhaust system in a performance vehicle like the GR Corolla. The exhaust system not only helps expel gases from the engine but also influences the sound profile of the car. An aftermarket exhaust can enhance performance, reduce weight, and provide a more aggressive sound.
Fujitsubo Exhaust Overview
The Fujitsubo exhaust system is renowned for its craftsmanship and performance benefits. Designed to provide a balanced sound profile, it aims to enhance the sporty nature of the GR Corolla while maintaining a level of refinement.

HKS Exhaust Overview
The HKS exhaust system is another popular choice among GR Corolla owners. Known for its aggressive sound, HKS aims to deliver a more pronounced exhaust note that amplifies the car’s performance characteristics.
- Material: High-quality stainless steel.
- Design: Optimized for maximum flow and performance.

Sound Test Methodology
To compare the Fujitsubo and HKS exhaust systems, we conducted a series of sound tests under controlled conditions. Both exhaust systems were installed on the same GR Corolla, and we recorded sound levels at idle, during acceleration, and at cruising speeds.

Conclusion
Both the Fujitsubo and HKS exhaust systems provide unique sound profiles that cater to different preferences. The Fujitsubo is ideal for those seeking a refined and sporty sound, while the HKS is perfect for enthusiasts looking for an aggressive and loud exhaust note. Ultimately, the choice between these two systems will depend on personal preference and desired driving experience.
