Arrow Indy-Race Carbon Slip-On Silencer Honda CBR 1000 RR SC77 (2017-2019) 71869MK

Road-legal and race-ready, the Arrow Indy-Race 71869MK is a full carbon slip-on silencer engineered specifically for the Honda CBR 1000 RR SC77. Carrying an E-number type approval for unrestricted street use, it pairs genuine weight savings — just 2.63 kg — with a measurably sharper throttle response and a power delivery that rewards every twist of the wrist.

Key Features

• E-number type approval confirms full road legality, so you can ride from the workshop straight to the track without paperwork concerns.
• Carbon fibre construction throughout the canister and end cap keeps weight to 2.63 kg, reducing unsprung and overall mass compared with the OEM unit.
• Stainless steel internals resist heat and corrosion, preserving performance over a long service life.
• Included db-killer allows sound level adjustment — remove it on circuit days, refit it for road use.
• Optimised flow geometry sharpens throttle response and delivers a noticeable increase in mid-to-top-end power output.
• Designed to combine with an Arrow header and the Arrow mid-pipe 71679MI to build a complete Arrow exhaust system.

Build Quality and Design

The Indy-Race canister is constructed from high-grade carbon fibre, chosen for its outstanding strength-to-weight ratio and exceptional heat resistance. The matching carbon end cap finishes the silencer with a purposeful, race-inspired aesthetic that complements the SC77's aggressive bodywork. Inside, stainless steel baffles and core components ensure the silencer maintains its performance characteristics even under sustained high-temperature operation on track.

Road and Track Use

The presence of an E-number makes the 71869MK one of the rare performance exhausts that genuinely serves both environments without compromise. For everyday road riding, the db-killer controls noise output to compliant levels. On track days, removing the db-killer opens the system fully, delivering the unmistakable Arrow sound alongside every fraction of available performance gain. A custom ECU remap is strongly recommended to fully realise the power and throttle-response improvements this silencer enables.

Compatibility Note

This slip-on silencer is not compatible with the standard Honda OEM mid-pipe. It must be used in conjunction with the Arrow mid-pipe 71679MI. For a full system, it can be paired with an Arrow header and the Arrow mid-pipe 71679MI.
