The Akrapovic Racing Line full exhaust system transforms the Kawasaki ZX-10 R/RR (2021–2025) into a sharper, lighter, more focused track weapon. A 4-2-1 stainless steel header feeds into an octagonal carbon silencer with titanium internals and a carbon end cap, shaving 4.9 kg from the stock system while unlocking an additional 11.1 hp and 13.4 Nm of torque.
Key Features
- Massive weight saving: 4.9 kg lighter than stock (6.7 kg vs 11.6 kg OEM)
- Power gain of 11.1 hp, reaching 198.4 hp at 13,900 RPM
- Torque increase of 13.4 Nm achieved at 3,600 RPM
- Sound level raised by 11.7 dB to a race-ready 105.5 dB
- Octagonal carbon silencer with titanium internals keeps mass to an absolute minimum
- Carbon end cap and carbon silencer bracket (optional, when passenger footpegs are removed) complete the premium aesthetic
Build Quality and Materials
Akrapovic's engineers have constructed the Racing Line header from V4A stainless steel with a lambda connection port, ensuring robust heat resistance and precise collector geometry for optimised scavenging. The octagonal silencer canister is formed from woven carbon fibre, paired with titanium internals that dissipate heat efficiently while further reducing rotational and unsprung mass. The carbon end cap adds a purposeful race-shop finish. Every joint, weld and sleeve reflects the same manufacturing discipline Akrapovic applies to its World Superbike homologation builds.
Track Use and Tuning Notes
The Racing Line carries no road-legal type approval and is intended exclusively for closed-circuit competition use. To realise the full power and torque gains — and to protect engine longevity — an ECU remap is required after fitment. An optional dB-Killer (DB-Eater) is available separately for circuits with noise restrictions. An optional carbon silencer bracket is also available when the passenger footpegs are removed, keeping the installation clean and weight at a minimum.
