Side-exit exhausts are a rare and distinctive feature that adds a touch of flair and power to any vehicle. They are often associated with high-performance cars, but their history and purpose go beyond mere aesthetics. In this article, I'll delve into the fascinating world of side-exit exhausts, exploring their origins, design considerations, and the cars that have made them iconic. From the classic to the cutting-edge, these exhaust systems offer a unique blend of performance and style that continues to captivate car enthusiasts worldwide.
A Historical Perspective
Side-exit exhausts have a rich history, dating back to the early days of automotive engineering. One notable example is the TVR Sagaris, a car known for its aggressive design and powerful engine. The Sagaris' exhaust system, positioned on the sides, not only contributed to its distinctive sound but also showcased the engineering prowess of TVR. This design choice allowed for optimal engine performance while also providing a visual statement that left a lasting impression on onlookers.
Another iconic car with side-exit exhausts is the Dodge Viper. The Viper's exhaust system, with its unique manifold and exhaust design, produced a sound that was both captivating and distinct. This attention to detail in exhaust engineering is a testament to the dedication of car manufacturers to creating a symphony of power and sound.
Aerodynamics and Performance
The inclusion of side-exit exhausts in certain vehicles goes beyond aesthetics. For instance, the Mercedes-McLaren SLR incorporated side-exit pipes to maintain the car's flat floor and rear diffuser, ensuring optimal aerodynamics. This design choice not only enhanced the car's performance but also paid homage to the original SLR from the 1950s, which featured similar exhaust placement. Such a blend of historical nod and modern engineering showcases the evolution of car design.
Practical Considerations
In some cases, side-exit exhausts serve practical purposes. The Caterham Seven, a lightweight sports car, uses side-exit exhausts to direct exhaust gases away from the driver's legs when entering or exiting the vehicle. This design consideration ensures a more comfortable driving experience, especially in a car that prioritizes performance and agility.
Iconic Models and Their Exhausts
Several iconic cars have made side-exit exhausts a signature feature. The Shelby Daytona Coupe, with its dual side-exit exhausts, produced a powerful sound that matched its 390bhp 4.7-litre Ford V8 engine. This design not only contributed to the car's performance but also made it a collector's item, with original models commanding multi-million-dollar premiums at auctions.
The Jaguar XKSS, a street-legal version of the legendary D-Type, featured side pipes that ran hot and spat fire. Jaguar, however, added a guard plate to ensure the exhausts were safe for public use. This attention to detail showcases the brand's commitment to both performance and safety.
Modern Innovations
In the modern era, side-exit exhausts continue to evolve. The Chevrolet Corvette C2 offered an 'off-road exhaust' package in the 1960s, which was actually designed for on-track performance. This innovative approach to exhaust design highlights the versatility and adaptability of side-exit systems.
Additionally, the Singer DLS-T showcases the challenges and benefits of side-exit exhausts in rear-engined cars. By steering exhaust gubbins away from the rear diffuser, Singer created a unique and functional design solution.
Conclusion
Side-exit exhausts are more than just a visual flourish; they represent a blend of history, engineering, and performance. From the classic designs of the past to the innovative solutions of today, these exhaust systems continue to captivate car enthusiasts and engineers alike. As automotive technology advances, we can expect to see further innovations in exhaust design, pushing the boundaries of what's possible in terms of sound, performance, and aesthetics.
