Arrow GP2 Slip-On Silencer Dark Stainless Steel BMW S1000RR K67 (2019-2026) 71554GPI

Built for riders who demand race-derived performance from their BMW S1000RR K67, the Arrow GP2 71554GPI slip-on silencer delivers a sharper throttle response, a genuine weight saving of 1.72 kg, and the aggressive dark stainless aesthetic that belongs on a machine capable of competing at the front of any grid.

Key Features

• Dark stainless steel canister with stainless steel end cap and internal components — corrosion-resistant, heat-tolerant and built to endure season after season of hard use.
• Weighs just 1.72 kg, trimming unsprung and overall mass to improve handling precision and corner-entry stability.
• E-number road approval included, with a removable dB killer so you can run unrestricted on track and compliant on the road.
• Inlet diameter 60 mm, outlet diameter 58 mm, overall length 200 mm — precision-engineered to flow freely and match the S1000RR's combustion characteristics.
• Direct bolt-on fitment replaces the stock silencer; expandable to a full system by pairing with a compatible Arrow header for maximum power and throttle response gains.
• Arrow recommends a dedicated ECU remap to unlock the full performance potential when fitted.

Track Performance & Build Quality

The GP2 series is Arrow's response to riders who spend as much time on circuit as on the road. The dark stainless finish is not merely cosmetic — the treated surface resists discolouration under sustained high-heat conditions far better than a polished canister, keeping the exhaust looking purposeful after back-to-back track sessions. Every internal component is stainless steel, eliminating the corrosion pathways that degrade sound quality and flow efficiency over time.

At 1.72 kg the GP2 slip-on is a meaningful improvement over the S1000RR's factory silencer. That mass reduction sits high and to the rear of the chassis, where cutting weight has a disproportionate effect on the bike's agility under braking and in direction changes — something immediately felt when pushing hard through a technical section.

Road & Everyday Usability

The supplied dB killer keeps noise levels within legal limits for road use, and because it is removable you are not compromising track performance to maintain road legality. The E-number type approval means fitting the GP2 with the dB killer in place satisfies EU roadworthiness requirements, so the silencer doubles as a practical daily upgrade as well as a circuit weapon.

Installation follows a straightforward plug-and-play process — no cutting, no custom fabrication. If you later decide to upgrade to a full Arrow exhaust system, the 71554GPI integrates directly with the matching Arrow header, turning your slip-on investment into the foundation of a complete, flow-matched system.

Fitment & Compatibility

This silencer is engineered exclusively for the BMW S1000RR K67, covering model years 2019 through 2026. It is compatible with the standard Arrow header to form a full exhaust system. Always verify your exact build date and variant before ordering.
