When it comes to performance cars, one cannot ignore the distinct sound of a Subaru with its big exhaust system. The Subaru brand has developed a reputation for its aggressive roar, partly due to the size of its exhaust system. In this blog, we will delve into the reasons why Subaru has opted for a large exhaust system in their vehicles.
Performance Enhancement:
One of the primary reasons Subaru has a big exhaust system is to improve the performance of their vehicles. A larger exhaust system allows for better airflow, which means improved engine combustion and increased power output. A free-flowing exhaust system reduces back-pressure, enabling the engine to breathe more efficiently and maximize its potential horsepower and torque. This results in a more responsive and exhilarating driving experience.
Turbocharged Engines:
Subaru is known for its implementation of turbocharged engines, particularly in models like the WRX and STI. Turbocharging forces more air into the engine, increasing its power output. However, it also generates more exhaust gases that need to be expelled efficiently. A larger exhaust system ensures that the turbocharged engine can expel these gases with minimal restriction, allowing for optimal performance and turbo response.
Unleashing the Signature Sound:
The distinct sound of a Subaru's big exhaust system is a crucial part of its identity. Subaru enthusiasts often refer to it as the "Subaru rumble." The unequal length headers, another unique characteristic of Subaru engines, contribute to this signature sound. The combination of a large exhaust system and unequal length headers creates a deep, throaty exhaust note that is instantly recognizable. This sound adds to the overall driving experience and feeds the passion of Subaru enthusiasts.
Aesthetic Appeal:
Beyond performance benefits, a big exhaust system can also enhance the visual appeal of a Subaru. The larger exhaust tips serve as a statement of the car's sporty nature, adding a touch of aggression to the rear end. Some Subaru models feature quad exhaust tips, which further enhance the visual impact and give the vehicle a more aggressive and performance-oriented look.
Tradition and Rally Heritage:
Subaru has a rich rally heritage, and its big exhaust system is a nod to its racing legacy. In rally racing, a large exhaust system is often used to optimize performance and enhance power delivery. By incorporating a similar design into their production cars, Subaru maintains a link to their rally roots and exudes a racing-inspired persona.
The combination of performance enhancement, turbocharged engines, signature sound, aesthetic appeal, and a tribute to Subaru's rally heritage are the driving forces behind the presence of a big exhaust system in Subaru vehicles. This design choice not only improves the overall performance of the car but also adds to the exciting and exhilarating experience for drivers and enthusiasts. So, if you've ever wondered why the Subaru has a big exhaust system, it's all about amplifying the power and creating a thrilling driving experience that represents the spirit and passion of the brand.
