Product Description

The Akrapovič Slip-On Titanium Exhaust System for the BMW F8X M3 and M4 is a premium, performance-oriented upgrade that enhances both sound and driving dynamics with high-quality materials and engineering. Constructed from lightweight titanium with select cast components, this slip-on exhaust replaces the restrictive stock rear section to significantly reduce weight, lower backpressure, and deliver increased power and torque — especially in the mid-range. Its acoustic calibration emphasizes deeper, richer tone and a more engaging sound experience at part- and full-throttle while preserving overall drivability. Finished with optional titanium or carbon-fiber tailpipes, this Akrapovič system also elevates the rear-end appearance of your M3/M4.

Fitment Notes

  • Direct fit for BMW M3 (F80) and BMW M4 (F82/F83) with S55 twin-turbo engine.

  • Also fits M3/M4 Competition and M3/M4 CS (Sport Club) variants — confirm fitment based on body style and OEM exhaust hardware.

  • Replaces the factory rear exhaust section (slip-on) — retains OEM front sections and catalytic converters.

  • Tailpipes and sound kit sold separately (titanium or carbon tips).
