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.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRace-only homologation — designed and built exclusively for closed-circuit competition use, not road legal.\u003c\/li\u003e\n\u003cli\u003ePremium stainless steel construction provides exceptional heat resistance and long-term durability under race conditions.\u003c\/li\u003e\n\u003cli\u003e54 mm outlet diameter optimises exhaust gas velocity for improved mid-range pull and top-end power.\u003c\/li\u003e\n\u003cli\u003eCompatible with the original OEM slip-on silencer or Arrow Slip-Ons 71207 and 71855, giving flexibility in your exhaust build.\u003c\/li\u003e\n\u003cli\u003eWeighs 4.40 kg, striking the right balance between structural integrity and reduced unsprung mass.\u003c\/li\u003e\n\u003cli\u003eECU remapping strongly recommended to unlock the full performance benefit and protect engine longevity.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eArrow'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.\u003c\/p\u003e\u003ch2\u003eTuning Recommendation\u003c\/h2\u003e\u003cp\u003eTo 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.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis header is designed as a direct fit for the Suzuki GSX-R 1000 covering model years 2017 through to 2023.
