Shedding 3.5 kg over the stock system and unlocking an additional 7.1 PS at 13,300 RPM, this 4-2-1 Evo-2 configuration is as close to a factory superbike specification as a road-derived machine can get.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDramatic 3.5 kg weight reduction — from 8.0 kg stock down to just 4.5 kg — sharpening steering response and reducing unsprung mass\u003c\/li\u003e\n\u003cli\u003eGains of 7.1 PS (203.5 PS to 209.7 PS at 13,300 RPM) and 3.8 Nm of additional torque at 7,700 RPM for a noticeably stronger mid-range and top-end pull\u003c\/li\u003e\n\u003cli\u003e4-2-1 full titanium Evo-2 configuration with lambda sensor port, ensuring compatibility with modern fuel injection mapping\u003c\/li\u003e\n\u003cli\u003eHexagonal silencer with carbon fibre canister and carbon end cap — optimised for mass centralisation as well as aesthetics\u003c\/li\u003e\n\u003cli\u003eEvery metallic component — including the internal baffling — is manufactured from titanium for absolute consistency in heat resistance and longevity\u003c\/li\u003e\n\u003cli\u003edB killer included for versatility between track sessions and controlled road use where regulations permit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSound and Character\u003c\/h2\u003e\u003cp\u003eThe Evolution Line raises the exhaust note by 10.5 dB relative to the standard system — from 96 dB to 106.5 dB measured at 5,500 RPM. The result is a hard-edged, purposeful howl that reflects the RSV4's V4 character without artificial amplification. On track the sound profile is immediately recognisable; the dB killer allows a degree of attenuation when circumstances require.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Materials\u003c\/h2\u003e\u003cp\u003eAkrapovic's Evolution Line is distinguished from the Slip-On range by replacing virtually every component of the OEM exhaust. The headers, mid-section and collector are all precision-welded titanium, produced to the same exacting tolerances used in Akrapovic's WorldSBK and MotoGP programmes. Carbon fibre is used for the outer silencer sleeve and end cap — materials chosen for their stiffness-to-weight ratio and thermal stability under sustained track use. The hexagonal silencer profile is a structural choice as much as a visual one, resisting torsional flex under hard acceleration.\u003c\/p\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eThis system replaces the standard passenger footpeg hangers; the pillion footpegs cannot be retained. A dedicated exhaust bracket is supplied in the kit.
