The Scorpion GPF-Back System has been specially developed for the BMW 128TI F40, produced between 2021 and 2024, and offers a perfect combination of performance and style. This 70mm / 2.75" diameter system is designed to optimize exhaust gas flow while reducing weight compared to the original system. Its high-quality construction from T304 aerospace-grade stainless steel ensures the system can withstand the toughest conditions while offering an impressive lifespan. The Scorpion GPF-Back System is equipped with an electronic valve, which can be controlled by the driver via the in-car drive mode button. This allows the sound level to be adjusted to suit driving conditions and personal preference. With the valves closed, the system produces a deeper, quieter tone, ideal for long journeys, while opening the valves fully releases the powerful exhaust note. In addition to the improved performance, the design is also aesthetically pleasing, with a choice of two handcrafted styles of the signature Scorpion tailpipes: Polished Daytona or Carbon Ascari. This allows drivers to customize the look of their car without sacrificing performance. For those looking For further performance improvements, Scorpion has also developed a GPF Delete, resulting in improved gas flow and noise performance (closed circuit use).
