Akrapovic Titanium Axle-Back for BMW X3M and X4M F97 F98 Competition

Transform your fast BMW SUV with Akrapovic’s titanium rear section. This valve-controlled, OPF and GPF friendly system unlocks a deeper, richer straight-six soundtrack, sharper throttle response and meaningful weight savings without the cabin drone you do not want. EU ECE type approved as the rear section only. Part number S-BM/T/10H.

Why this titanium rear section is the upgrade your X3M or X4M needs

• Lightweight titanium construction for a serious strength to weight advantage and long-term durability.
• Active valve technology with precision cast housings for quiet cruising and full-blooded performance sound on demand.
• Sound tailored for BMW’s turbo straight-six. Deep tone at low rpm, crisper upshifts, no intrusive drone.
• Real gains you can feel. Up to +5.4 kW at 6550 rpm and +12.8 Nm at 3400 rpm versus stock with a 9.5 kg reduction.
• Beautiful finish with signature Akrapovic tailpipe options to complete the rear end aesthetics.
• ECE compliant when used as the rear section only, ideal for OPF and GPF equipped cars.

How it improves your drive

Developed and validated by Akrapovic engineers, this axle-back improves response and adds character across the rev range while trimming significant mass from the back of the car for a more agile feel. On the road it delivers a more engaging drive and that unmistakable Akrapovic tone. We have installed this system for X3M and X4M owners and customer feedback on fit, finish and sound has been consistently excellent.
