Why enthusiasts choose this upgrade

  • Valved system that integrates with the original in‑car controls for seamless operation
  • Quad 84 mm slash‑cut carbon fibre tailpipes with titanium inners for a premium finish
  • Handcrafted in Austria with a shot‑peened, full stainless steel construction
  • Engineered for low back‑pressure to enhance flow and throttle response
  • Lighter than the factory system for improved dynamics
  • Direct bolt‑on fit with precision alignment for perfect rear bumper aesthetics

Sound and driveability

With the valves closed you get a deeper, more purposeful note for daily use. Open the valves and the S58 comes alive with a race‑bred character that remains crisp and refined. Our team has fitted this system on customer cars and feedback has been consistently outstanding for tone quality, finish and fit.

Fitment and compatibility

Designed for BMW X4 M Competition F98 (S58B30A, 2019+). Retains the original valve electronics and control strategy for true plug‑and‑play operation.

Important information
