Certified and road-legal with the DB-Killer fitted, it drops 1.4 kg from the stock weight — from 3.6 kg down to just 2.2 kg — sharpening throttle response and improving chassis balance in a single bolt-on upgrade made entirely in Italy.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRoad-legal configuration achieved via the removable DB-Killer, which reduces output to approximately 99 dB at 5,500 rpm — keeping the system compliant for street use without permanent modification.\u003c\/li\u003e\n\u003cli\u003eTitanium canister construction delivers high-temperature resistance and long-term durability at a fraction of the weight of the OEM silencer.\u003c\/li\u003e\n\u003cli\u003eCarbon end-cap adds structural rigidity and a purposeful race-bred aesthetic to complement the titanium body.\u003c\/li\u003e\n\u003cli\u003eWithout the DB-Killer, sound output rises to approximately 104 dB at 5,500 rpm, unlocking the full aggressive character of the Force Evo for track days.\u003c\/li\u003e\n\u003cli\u003eWeight saving of 1.4 kg directly lowers unsprung and rear mass, improving the RSV4's already impressive chassis dynamics and corner-entry balance.\u003c\/li\u003e\n\u003cli\u003eComplete fitting hardware included — all exhaust springs and the full mounting kit ship in the box, making installation straightforward.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality \u0026amp; Performance\u003c\/h2\u003e\u003cp\u003eSpark Exhaust manufactures the Force Evo in Italy, applying the same construction philosophy used across their race catalogue. The titanium canister is formed and welded to exacting tolerances, resisting corrosion and heat cycling across seasons of hard use. The carbon end-cap is not purely cosmetic — it reinforces the outlet and contributes to the overall stiffness of the assembly, resisting the vibration loads typical of high-revving V4 engines like the Aprilia.\u003c\/p\u003e\u003cp\u003eThe removable DB-Killer is the centrepiece of the Force Evo's dual-purpose design. Installed, it brings the system into compliance for road registration in markets requiring a type-approval silencer. Removed, it opens the full exhaust note — a deep, layered V4 soundtrack at 104 dB — suited to closed circuit use. The transition between the two configurations requires no tools beyond what comes in the mounting kit.\u003c\/p\u003e\u003ch2\u003eRoad \u0026amp; Track Use\u003c\/h2\u003e\u003cp\u003eFor street riding, Spark Exhaust recommends fitting the DB-Killer to meet noise regulations and to maintain driveable low-rpm fuelling behaviour. On track, removing the DB-Killer and running a dedicated race map or a custom dyno tune will allow the engine to realise the full benefit of the improved exhaust flow. A remap or dyno session is strongly advised to extract the complete performance potential of this system.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis slip-on is designed as a direct, bolt-on replacement for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAprilia RSV4 (2017-2020)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 1100 Factory (2017-2020)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RF (2017-2020)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RR (2017-2020)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003ePart number: GAP0407.
