The Arrow Competition full exhaust system 71215CKZ is engineered exclusively for track use on the Aprilia RS 660, covering model years 2020 to 2024. Built entirely from titanium — header, silencer body and internals alike — it strips weight down to just 4.21 kg while sharpening throttle response and unlocking the RS 660's full power potential lap after lap.
Key Features
- Full titanium construction throughout: header, silencer body and internal components for an exceptional strength-to-weight ratio and outstanding heat resistance.
- Total system weight of just 4.21 kg delivers a meaningful reduction over the stock exhaust and directly improves power-to-weight performance on track.
- Carbon end cap adds a purposeful, race-bred aesthetic while resisting the intense heat generated during hard circuit riding.
- Removable dB killer allows straightforward noise adjustment to suit circuit regulations without additional tools.
- Silencer outlet diameter of 58 mm and overall silencer length of 270 mm are optimised for the RS 660's engine character.
- Plug-and-play fitment engineered specifically for the RS 660 chassis — no cutting or fabrication required.
Race-Ready Performance
Arrow's Competition series represents the Italian brand's most focused track offering. Every dimension and material choice in the 71215CKZ has been developed around extracting the maximum from the Aprilia RS 660's parallel-twin engine. The full titanium header retains heat efficiently to maintain exhaust gas velocity, supporting stronger mid-range pull and a cleaner top-end delivery. Paired with the carbon-capped titanium silencer, the system produces a sonorous, unmistakable race note that rewards every twist of the throttle.
Please note: this system is approved for race use only and is not road-legal. For best results, a custom engine mapping tailored to the Arrow Competition system is strongly recommended to fully realise the performance gains on offer.
