Arrow Stainless Steel Header Honda CBR 1000 RR-R SC82 (2020-2023) 71736MI

The Arrow 71736MI header brings genuine performance gains to the Honda CBR 1000 RR-R SC82 without demanding a full exhaust overhaul. Built from high-grade stainless steel and engineered specifically for the SC82 platform, it slots neatly into your existing setup or pairs with a range of Arrow slip-on silencers — making it one of the most practical first steps toward a freer-breathing exhaust system.

Key Features

• Purpose-designed for the Honda CBR 1000 RR-R SC82 (2020–2023) for a precise, rattle-free fit straight out of the box.
• High-grade stainless steel construction delivers exceptional heat resistance and long-term durability under sustained track use.
• Improves throttle response and overall power delivery compared to the factory header.
• Compatible with the OEM silencer, so you can upgrade in stages without replacing everything at once.
• Directly compatible with Arrow slip-on silencers 71921PK, 71155PR, 71005PT and 71005PTN for a complete Arrow exhaust solution.
• 66 mm outlet diameter ensures consistent flow alignment with compatible silencers.

Build Quality and Performance

Arrow's stainless steel header tubing is precision-formed to match the SC82's exhaust port geometry, promoting smooth gas flow from each cylinder. At 3.72 kg the header represents a meaningful reduction over the heavier stock unit, contributing to a slightly lower centre of gravity and a livelier feel through transitions. The material choice — stainless steel rather than mild steel — resists the discolouration and surface degradation that track heat cycles accelerate, so the header holds up across a full season of use without looking neglected.

Mapping Recommendation

To extract the full benefit of the improved flow characteristics, a dedicated ECU remap is strongly recommended after fitting. Running a remapped fuelling strategy alongside this header will optimise throttle response across the rev range and protect the engine long-term by correcting the air-fuel mixture for the reduced back-pressure.

Fitment and Compatibility

This header is engineered exclusively for the Honda CBR 1000 RR-R SC82 covering model years 2020, 2021, 2022 and 2023. It is not a universal fitment. Compatible silencers include the OEM Honda unit and the following Arrow slip-ons:

• Arrow 71921PK
• Arrow 71155PR
• Arrow 71005PT
• Arrow 71005PTN

Race use only — this header does not carry road-use type approval and must not be used on public roads.
