DescriptionThe whole story▼
The Arrow 71627KZ stainless steel mid-pipe is the precision-engineered link between your stock headers and an Arrow slip-on silencer, purpose-built for the Aprilia RSV4, RSV4 RR and RSV4 RF of 2015 and 2016. At just 0.85 kg it sheds meaningful mass over the OEM section, sharpening throttle response and freeing up power across the rev range — exactly the kind of marginal gain that separates fast road riding from genuine track performance.
Key Features
- Fabricated from high-grade stainless steel for lasting corrosion resistance and the clean, purposeful look the RSV4 deserves.
- Integrated catalyst meets Euro 5 standards and carries an E-number homologation, keeping the bike fully road-legal.
- Weighs only 0.85 kg — a direct weight saving over the original mid-section that benefits both straight-line acceleration and handling balance.
- Bolt-on fitment to the original Aprilia header; no modification to the stock exhaust manifold required.
- Designed exclusively for use with an Arrow slip-on silencer, ensuring a perfect gas seal and matched flow characteristics.
- ECU remapping is recommended after installation to unlock the full performance and throttle-response gains on offer.
Track Performance & Road Use
The RSV4 platform is a proven race-derived superbike, and the Arrow exhaust system has been a fixture in both World Superbike paddocks and club racing for good reason. The 71627KZ mid-pipe maintains that competition pedigree: the stainless construction withstands the sustained high-temperature cycles of track use far beyond what a standard system tolerates, while the integrated catalyst means you can ride to the circuit and back without worrying about emissions testing or road-legal compliance. Pair it with any Arrow slip-on — Race-Tech, Pro-Race or Thunder — and the combined system delivers the exhaust note and mid-to-top-end sharpening the RSV4's V4 engine is capable of.
Installation Notes
The 71627KZ connects directly to the original Aprilia exhaust header and is compatible only with Arrow slip-on silencers. It is not designed for use with third-party or OEM end cans. For best results, have the ECU reprogrammed to suit the revised exhaust flow after fitting; this step is strongly recommended to realise the full performance and throttle-response improvement the system offers.
