DescriptionThe whole story▼
Crafted entirely from aerospace-grade titanium, the Akrapovic Slip-On Line for the Honda CBR1000RR SC77 (2017–2019) sets the benchmark for what a slip-on silencer can deliver. Every metallic component — shell, end cap, and internal structure — is titanium, resulting in a dramatic 2.3 kg saving over the standard unit and a sound signature that is unmistakably GP-derived.
Key Features
- Full titanium construction throughout: titanium shell, titanium end cap, and titanium internals on the GP 1 silencer
- 2.3 kg weight reduction over stock (OEM: 3.3 kg / Akrapovic: 1.0 kg), transforming the bike's mass centralisation
- Measurable power gain of +0.5 hp at 10,950 RPM (177.6 hp vs. 177.1 hp stock)
- +2.5 Nm additional torque at 6,600 RPM for stronger mid-range drive
- +15 dB sound increase over standard (114.5 dB vs. 99.5 dB at 6,500 RPM) — a genuine race exhaust note
- Plug-and-play fitment onto the original header — no cutting or welding required (ECU reprogramming recommended)
- Optional headers available separately for further power and torque gains
Build Quality and Materials
Akrapovic's Slip-On Line is built to the same philosophy as their race-homologated systems. Unlike silencers that use titanium only for the outer skin, this unit uses titanium for every metallic element — the canister shell, the end cap, and the internals — which is why the weight drops to a remarkable 1.0 kg. The GP 1 silencer profile is directly influenced by Akrapovic's MotoGP programme, giving it a purposeful, compact form that sits tight to the subframe and keeps mass low and central.
Performance and Sound
The gains recorded on the Honda CBR1000RR SC77 are real and dyno-verified. The +0.5 hp at 10,950 RPM complements a more significant mid-range improvement: +2.5 Nm at 6,600 RPM means the engine responds more willingly when accelerating out of slow and medium-speed corners — exactly where track times are won. The 15 dB increase in exhaust note lifts the character of the inline-four from composed sports tourer to race machine, without the artificial rasp of steel or aluminium units.
Track Use and Important Notice
This system carries no road-use homologation and is intended exclusively for closed-circuit, competition use. It does not meet the noise or emissions requirements for public roads in any European jurisdiction. Fitting requires ECU reprogramming to realise the full performance benefit; Akrapovic recommends using their own map or a specialist remap service.
Fitment and Compatibility
This slip-on silencer is a direct replacement for the standard unit on the following model:

The system connects directly to the original OEM header. Optional Akrapovic headers are available separately for riders seeking the maximum power and torque increase.
