Akrapovič Slip-On Line (Titanium) – BMW X3 M (F97) / X4 M (F98)
Part Number: S-BM/T/29H
Transform the character, sound, and performance of your BMW X3 M or X4 M with the Akrapovič Slip-On Line (Titanium) — a precision-engineered exhaust system crafted to deliver measurable gains without compromising refinement.
Constructed entirely from lightweight high-grade titanium, this system reduces weight by 9.5 kg (41.1%) compared to the stock M Sport exhaust. Designed for seamless integration with OPF/GPF-equipped models, it is fully ECE type-approved, requires no ECU remapping, and is road legal where ECE approval applies.
Sound: Refined When Cruising, Aggressive When Driven
Specifically tuned for BMW’s twin-turbo inline-six, the Slip-On Line enhances exhaust volume while maintaining everyday usability. The tone builds progressively through the rev range, delivering:
A deeper, richer exhaust note
Dynamic acoustic feedback on gear shifts
Zero intrusive drone at cruising speeds
For drivers wanting full sound control, the optional Akrapovič Sound Kit allows independent valve operation at the press of a button.
Performance: Lighter, Sharper, More Responsive
By optimising gas flow and reducing back pressure, the system delivers proven dyno gains:
+7.3 hp at 6,550 rpm
+9.4 ft-lb at 3,400 rpm
–9.5 kg (41.1%) weight reduction
The result is improved throttle response, enhanced agility, and a more engaging driving experience across the entire rev range.
Design: Titanium Craftsmanship Meets Carbon Detail
Manufactured by Akrapovič, the system features:
Full titanium construction
Titanium valve housings cast in-house
Dual pairs of carbon fibre/titanium tailpipes (mandatory)
The finish perfectly complements the aggressive styling of the BMW X3 M and X4 M, delivering OEM-level integration with motorsport presence.
