This valved catback for the X3 M and X4 M uses an equal-length, resonated layout. Balancing the exhaust pulses smooths out uneven frequencies, so the S58 takes on a cleaner, more exotic tone than the factory system. The valves stay tied to the car's own drive modes.

What you get

  • Equal-length resonated design for a smooth, motorsport-style sound.
  • Electronic valves wired into the OEM M1/M2 modes, so sound changes with the drive mode you pick.
  • Fully mandrel-bent piping for flow.

Pick your options

  • Material: Grade 5 titanium or T304 stainless.
  • Tips: Carbon Fiber, Black or Brushed.
