Engineered for the S55 Twin-Turbo Platform

Unlock a cleaner, deeper, and more aggressive sound from your BMW F80 M3, F82 M4, or F83 M4 with the AeroFlowDynamics RS Valved Exhaust System.

Designed specifically for the BMW S55 twin-turbo inline-six engine, the RS system transforms the factory exhaust tone into a stronger, bass-heavy performance sound while reducing the harsh rasp commonly found on the F8X M3 and M4 platform.

Fitment

2015–2020 BMW F83 M4 Convertible

Fits BMW S55 twin-turbo models.

Unlike many aftermarket exhaust systems that make the S55 sound overly metallic, tinny, or raspy, the AeroFlowDynamics RS system is engineered to deliver a smoother and deeper tone with an aggressive performance character.

This system uses our AFD aftermarket valve system, giving drivers control over the sound. Keep the valves closed for a more refined daily driving tone, or open the valves for a louder, deeper, and more aggressive exhaust note.

Premium 304 Stainless Steel Construction

The AeroFlowDynamics RS Exhaust System is constructed from high-quality 304 stainless steel, known for its durability, corrosion resistance, and long-term reliability in high-performance exhaust applications.

This premium material allows the exhaust system to withstand high temperatures, aggressive driving conditions, and long-term use while maintaining its sound quality, structure, and performance.

Refined Sound Engineering – No Rasp / Deep Bass Tone

Many aftermarket exhaust systems for the BMW S55 engine can produce unwanted rasp, drone, or harsh metallic frequencies, especially under acceleration and higher RPM.

The AeroFlowDynamics RS Exhaust System was engineered to eliminate those issues.

Through carefully designed piping, optimized sound control, and our AFD aftermarket valve system, the RS system delivers a deeper, smoother, and more aggressive performance tone with reduced rasp.
