Ford Mustang MK6/7 tuning parts

The Ford Mustang, across its recent generations, represents the modern pinnacle of American muscle car performance and technology. The MK6 (S550), introduced in 2015, marked a revolutionary step, bringing independent rear suspension (IRS) to the Mustang line globally, vastly improving handling and ride quality compared to its predecessors. For its later model years (2018 onwards), the S550 integrated an optional Active Valve Performance Exhaust system, allowing the driver a degree of control over the roar of the iconic 5.0-litre Coyote V8 engine through various drive modes. The subsequent MK7 (S650), launched in 2024, maintained the fundamental architecture of the S550 while significantly modernizing the interior with a large, integrated digital dashboard and further refining the drivetrain for minor performance gains and chassis tuning, ensuring the Mustang remains a powerful, track-capable, and globally relevant sports coupe.

While both the S550 and S650 offer the desirable Active Valve Exhaust, its control is ultimately dictated by the car's Engine Control Unit (ECU). The ECU automatically opens and closes the exhaust flaps based on predefined rules related to RPM, throttle position, and selected drive mode, which can prevent the driver from achieving the loudest possible sound during specific scenarios, such as cruising or coming to a stop. This lack of true manual control often frustrates enthusiasts who want instantaneous, unbridled sound on demand, regardless of the car’s current operating conditions or drive mode setting.

This is where Capristo's offerings provide a tailored solution. The Capristo E2E (Electronic to Electronic) Exhaust Remote Kit A is a German-engineered, plug-and-play module designed specifically for the electric valve system on the late S550 and S650 Mustangs. By installing this module—which seamlessly "piggybacks" into the OEM wiring harness without cutting—the driver gains a dedicated wireless remote. This remote allows the user to instantly override the ECU's logic, forcing the exhaust valves completely open for maximum volume at any time, providing total command over the soundtrack of their modern Mustang.
