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

Street-legal, lightweight and genuinely transformative — the Arrow Indy-Race 71869PK is the most practical performance upgrade you can make to your Honda CBR 1000 RR SC77. At just 2.43 kg, this titanium slip-on silencer trims unsprung weight, sharpens throttle response and delivers a purposeful exhaust note that elevates every ride, whether you're commuting, touring or taking the occasional track day. The included E-number type approval means it goes straight on and stays road-legal from day one.

Key Features

• Titanium canister construction keeps weight to just 2.43 kg, reducing unsprung mass and improving handling feel immediately
• E-number road approval — fully street-legal straight out of the box, no MOT worries
• Removable dB killer lets you dial the volume down for daily riding or remove it for track sessions
• Carbon end cap adds a sharp, race-derived aesthetic that suits the SC77 CBR's aggressive lines
• Stainless steel internal components for long-term heat resistance and structural durability
• Compatible with Arrow header pipes to form a full Arrow exhaust system for maximum performance gains

Build Quality and Materials

Arrow engineered the Indy-Race specifically for the SC77 generation CBR 1000 RR, and the material choices reflect exactly what road riders need. The outer canister is formed from titanium — a metal that combines exceptional strength with a weight saving that cast or stainless alternatives simply cannot match. Internal baffles and core components are stainless steel, ensuring the silencer handles sustained heat cycles without degradation. The carbon end cap rounds off the package with a finish that looks at home on a machine that was always meant to be ridden hard.

Performance and Everyday Usability

The Indy-Race name comes from Arrow's race programme, but this silencer is equally at home in everyday use. Throttle response tightens perceptibly across the rev range, and mid-range pull feels more immediate than the standard unit. For road use, the dB killer moderates volume to a level that is civilised enough for early-morning runs without losing character. Remove it for the track and the CBR sounds exactly as it should. Arrow recommends a dedicated ECU remap to extract the full performance benefit, though the silencer delivers noticeable gains even without one.

Important Compatibility Notes

This slip-on silencer requires the Arrow mid-pipe 71679MI — it is not compatible with the original Honda mid-pipe. To build a complete Arrow exhaust system, pair it with an Arrow header set alongside the 71679MI mid-pipe. Please verify fitment before ordering.
