DescriptionThe whole story

Built without compromise for track and racing use, the Arrow Competition Evo 71161CKR is a full exhaust system engineered exclusively for the Suzuki GSX-R 1000 (2017-2023). Constructed entirely from titanium — header, silencer body and internals — and finished with a carbon end cap, this system delivers a measurable reduction in unsprung and total weight alongside genuine gains in throttle response and peak power output under race conditions.

Key Features

  • Full titanium construction throughout: header, silencer body and internal components for maximum heat resistance and minimum weight
  • Complete system weight of just 4.50 kg, contributing directly to improved handling and lap-time gains on circuit
  • Carbon end cap adds rigidity while keeping the aesthetic sharp and the weight low
  • Removable dB-killer insert allows sound output to be adjusted between sessions without tools
  • 58 mm outlet diameter and 300 mm silencer length optimised for the GSX-R 1000 power delivery
  • Race-use only homologation — designed to be run without the constraints of road-legal restrictions

Track Performance & Engineering

The Competition Evo designation signals Arrow's intent: this is not a road system with a race label attached. Every dimension, every material choice and every weld is calibrated for the demands of circuit riding on the GSX-R 1000. Titanium headers shed heat rapidly and resist the thermal cycling that destroys lesser systems during back-to-back sessions. The titanium silencer body pairs with titanium internals to produce an exhaust note and back-pressure curve that supports strong mid-range pull and a clean top-end charge.

At 4.50 kg for the complete assembly, the weight saving over the factory system is substantial. Reduced unsprung and chassis mass translates directly into sharper turn-in, more responsive braking and better overall balance — advantages that compound over the course of a race or trackday. Arrow recommends a dedicated ECU remap to fully unlock the performance potential of the 71161CKR on the Suzuki GSX-R 1000.

Build Quality & Materials

Arrow's Competition Evo systems are assembled in Italy to the same standards applied to their World Superbike-level components. The titanium used throughout offers an exceptional strength-to-weight ratio and natural corrosion resistance, meaning the system will survive the demanding environment of a race paddock season after season. The carbon fibre end cap is not merely cosmetic — it provides structural stiffness at the silencer exit while dissipating heat efficiently.

Important Notes

The Arrow 71161CKR is approved for race use only. It carries no road-use homologation and must not be used on public roads. The removable dB-killer is included to assist with noise compliance at circuits that impose sound limits; removing it is straightforward when regulations permit unrestricted output.
