Akrapovic Titanium Header BMW S1000RR K67 (2019-2026) E-B10E8

This full titanium 4-2-1 header from Akrapovic is the missing link between a slip-on setup and a true full-system exhaust on the BMW S1000RR K67. Machined and welded from aerospace-grade titanium throughout, it slashes 6.4 kg from the standard exhaust weight while unlocking a verified 10.4 hp and 8.8 Nm of additional torque — numbers that translate directly into faster exits and a harder mid-range punch on track.

Key Features

• Full 4-2-1 titanium construction: every pipe, collector and fitting is pure titanium — no steel compromise anywhere in the system
• Weight reduction of 6.4 kg over the OEM header (stock: 8.6 kg / Akrapovic: 2.2 kg), transforming the front-end mass balance of the S1000RR
• Dyno-verified power gain of 10.4 hp at 13,400 RPM (201.9 hp stock vs 212.3 hp with Akrapovic)
• Torque increase of 8.8 Nm at 8,450 RPM for a noticeably stronger mid-range drive
• Sound level rises by 9.9 dB to 107.9 dB at 6,500 RPM — unmistakeable Akrapovic racing note
• Supplied with all necessary mounting hardware for a clean, direct installation
• Compatible with the full range of Akrapovic slip-on systems for the S1000RR K67

Build Quality and Materials

Akrapovic's reputation in MotoGP and WorldSBK is built on one principle: use the lightest, most thermally resilient materials available and engineer every joint to racing tolerances. This header lives by that philosophy. The titanium alloy used resists heat-induced distortion at the extreme exhaust gas temperatures generated by the S1000RR's inline-four, maintaining consistent scavenging geometry across an entire race session. Weld quality is consistent with Akrapovic's motorsport production standard, with smooth internal bores that minimise turbulence at the collector — exactly where OEM headers typically surrender power.

Performance and Track Use

The gains recorded with this header are not theoretical. Akrapovic's own test figures show the S1000RR K67 producing 212.3 hp at 13,400 RPM and generating an additional 8.8 Nm at 8,450 RPM when this header replaces the factory unit. For track riders the combined effect is a broader, stronger power curve from mid-range through the rev ceiling. The 6.4 kg mass reduction is equally significant: removing weight from the exhaust plumbing lowers the centre of gravity and reduces rotational inertia, making the motorcycle noticeably more responsive to steering inputs. An optional catalyst is available separately for configurations that require it.

This header carries no road-use approval and is intended exclusively for closed-circuit competition use. Fitment to a road-registered vehicle is not permitted.

Fitment and Compatibility

Designed and engineered specifically for the BMW S1000RR K67, model years 2019 to 2026. Compatible with Akrapovic slip-on exhaust systems for the same model. The header is not compatible with the standard OEM silencer.
