• Silencer body: titanium.
• Silencer length: 265 mm.

Installation and use

• Manufacturer specifies closed-course competition use only; this is not a road-approved exhaust.
• Match the ECU calibration to the exhaust configuration. Any quoted development performance depends on the associated intake and tuning setup; tuning equipment is separate.
• R1S requires eight Yamaha exhaust nuts, part 90179-08442, sold separately.
• For 2020-onwards R1 applications, confirm the tuning arrangement before ordering: retaining the original front oxygen sensors requires a specially configured system with added ports.

Manufacturer part number: EXY-17R1-FTT26

Published measurements

• Published weight: original 22.8 lb; Graves 8.4 lb.
• Graves sound: 108 dB at 5,000 rpm.
