Akrapovic Evolution Line Titanium Full Exhaust System Honda CBR 600 RR PC69 (2024-2026) S-H6E5-ACT

The Akrapovic Evolution Line Titanium is a full 4-2-1 exhaust system engineered specifically for the Honda CBR 600 RR PC69 (2024-2026), delivering a verified 7.1 hp gain and a 4.7 kg weight saving straight out of the box. Whether you are preparing for track days or chasing lap times at circuit level, this system transforms the CBR's power delivery and soundtrack in a single fitment.

Key Features

• Saves 4.7 kg over the stock system (stock: 8.9 kg, Akrapovic: 4.2 kg) for a genuine improvement in handling and acceleration
• Adds 7.1 hp at 14,000 RPM (stock: 112.8 hp, Akrapovic: 119.7 hp) with a measurable torque increase of 2.7 Nm at 6,000 RPM
• Full 4-2-1 Evo-2 all-titanium construction including header, mid-pipe and silencer internals for consistent heat resistance and longevity
• Hexagonal silencer with titanium shell and carbon end cap — a purposeful race aesthetic with no excess weight
• Lambda connection integrated for straightforward sensor retention and tuning access
• dB-eater included, giving you flexible noise management between test days and competitive events

Build Quality and Performance

Every metallic component of the silencer — including the internal baffling — is machined or formed from titanium, not a hybrid construction. This approach eliminates the weight penalty of stainless mid-sections found on lesser systems and ensures even thermal expansion across the entire exhaust path. The Evo-2 header configuration has been flow-matched to the CBR 600 RR PC69's engine mapping, so the power and torque gains are achievable with a standard ECU remap rather than a full engine rebuild.

The hexagonal silencer profile is not purely cosmetic. The geometry stiffens the canister without adding wall thickness, which keeps the overall weight at 4.2 kg while maintaining structural integrity under sustained high-RPM use. The carbon end cap adds a further weight reduction at the rear of the system where heat management is most critical.

Track Use and Noise Management

This system is designed exclusively for closed-circuit racing and is not road-legal. The included dB-eater allows riders to meet circuit noise limits during practice and qualifying without removing the system or fitting a separate restrictor. Akrapovic recommends an ECU remap to realise the full power and torque figures quoted and to protect engine longevity under race conditions.

Fitment and Compatibility

This system is a direct fitment for the Honda CBR 600 RR in PC69 specification, covering model years 2024, 2025 and 2026. It is not compatible with earlier CBR 600 RR variants. Always confirm your frame and engine number against the PC69 designation before ordering.
