Arrow Competition EVO Full Titanium Complete Exhaust System – Aprilia RS 660 (2020-2024) 71215CP

The Arrow Competition EVO full system 71215CP is a race-bred titanium exhaust engineered from the ground up for the Aprilia RS 660. Constructed entirely from titanium — header, end cap, internals and slip-on silencer body — it delivers a dramatic weight reduction alongside the kind of purposeful, raw finish that reflects its pure circuit intent. This is the exhaust Arrow builds when nothing else matters but lap time.

Key Features

• Full titanium construction throughout: header, canister body, end cap and internals — maximum strength at minimum mass
• Complete system weight of just 3.51 kg for a significant reduction over the stock assembly
• Removable dB killer included for paddock compliance and flexible noise management
• Silencer dimensions of 270 mm overall length and 68 mm outlet diameter for optimised flow characteristics
• Plug-and-play fitment designed specifically for the RS 660 — no fabrication or modification required
• Race-use only homologation: built without compromise for closed-circuit performance

Design, Finish and Heritage

Arrow's Competition EVO series carries forward decades of Italian race exhaust expertise into a package that wears its purpose openly. The natural titanium finish develops a distinctive heat-blued patina through use, giving each system a character that is entirely its own. The silencer's clean lines and raw metal aesthetic complement the RS 660's angular bodywork, and every weld reflects the hand-finished quality that Arrow's Italian craftsmen have been delivering to World Superbike and domestic race paddocks for generations.

Titanium is specified here not as a premium cosmetic choice but as an engineering decision: the alloy combines exceptional tensile strength with outstanding resistance to the sustained thermal cycles a race engine produces, while shedding mass from a part of the motorcycle that sits well outside the centre of gravity. The result is a measurable improvement in handling agility alongside the performance gains unlocked by freer gas flow.

Performance and Track Use

The Competition EVO header geometry has been developed on the dyno and on track to maximise mid-range response and top-end power delivery on the RS 660's parallel-twin. The full system approach — replacing every component from the cylinder head flanges back — ensures the greatest possible gains compared to a slip-on solution alone. For riders seeking the full benefit of the system, a dedicated ECU remap tailored to the new exhaust is strongly recommended to realise optimum throttle response, power output and reliability under race conditions.
