G29 Z4 M40i Akrapovic Slip-On Exhaust S-BM/T/9H, Titanium & Carbon Fibre, ECE Approved, OPF/GPF Compatible

For the G29 Z4 M40i (B48TU engine, 2019+), this Akrapovic S-BM/T/9H slip-on replaces only the rear section - no cat-back or downpipe needed. It’s not an OEM replacement; it’s a fast road or track day upgrade that cuts 6.1 kg and sharpens throttle response without triggering check-engine lights on OPF/GPF-equipped cars.

• Fitment is exact: G29 Z4 M40i only - not for sDrive20i, M40i with manual, or pre-2019 models
• Stage 1 compatible: Works cleanly with stock ECU, OTS maps, or mild bolt-ons (intake, charge pipe)
• Sound profile: Deeper idle, aggressive crackle on lift-off, civilised in Comfort mode - ideal for daily driver or show car use
• Materials: Full titanium rear box + muffler, carbon-fibre quad tips - no steel, no compromise
