Engineered exclusively for track and race use, the Arrow 71660MI stainless steel header transforms the exhaust flow of the Suzuki GSX-R 1000 (2017-2023), delivering sharper throttle response and a measurable gain in power output. Built to withstand the relentless heat cycles of competition, this header is the foundation of a serious race exhaust build on the GSX-R platform.

Key Features

  • Race-only homologation — designed and built exclusively for closed-circuit competition use, not road legal.
  • Premium stainless steel construction provides exceptional heat resistance and long-term durability under race conditions.
  • 54 mm outlet diameter optimises exhaust gas velocity for improved mid-range pull and top-end power.
  • Compatible with the original OEM slip-on silencer or Arrow Slip-Ons 71207 and 71855, giving flexibility in your exhaust build.
  • Weighs 4.40 kg, striking the right balance between structural integrity and reduced unsprung mass.
  • ECU remapping strongly recommended to unlock the full performance benefit and protect engine longevity.

Performance & Build Quality

Arrow's 71660MI header is designed from the ground up to improve exhaust scavenging on the GSX-R 1000's inline-four. The stainless steel construction handles the extreme thermal loads found in race environments without warping or degrading over repeated hard sessions. The precision-formed collector and 54 mm outlet encourage a free-flowing, balanced exhaust pulse that translates directly into crisper throttle response and stronger acceleration out of slow corners.

Tuning Recommendation

To realise the full potential of this header and safeguard your engine, Arrow and Inter-Pace both recommend a dedicated ECU remap once the header is fitted. A bespoke fuel and ignition map will match fuelling to the revised exhaust characteristics, maximising power delivery across the rev range while preventing lean running conditions at high rpm.

Fitment & Compatibility

This header is designed as a direct fit for the Suzuki GSX-R 1000 covering model years 2017 through to 2023. It accepts the original OEM silencer canister without modification, and is equally at home paired with Arrow Slip-On silencers part numbers 71207 and 71855 for a full Arrow race exhaust system.
