SC-Project SC1-R Slip-On Silencer Honda CBR 1000 RR-R SC82 (2020-2023) H35A-T91

Forged from the same racing philosophy that powers SC-Project's MotoGP and WSBK programmes, the SC1-R Slip-On for the Honda CBR 1000 RR-R SC82 (2020-2023) is a masterclass in precision engineering. Every component — from the hydroform-pressed carbon end cap to the TIG-welded titanium collector with segmented bends — reflects an uncompromising commitment to materials quality that separates this silencer from anything resembling a production-line afterthought.

Key Features

• Hydroforming-manufactured carbon end cap for aerodynamic efficiency and reduced thermal mass
• Diamond-section silencer body delivering an immediately recognisable racing profile
• TIG-welded titanium connections throughout for exceptional joint integrity and long-term durability
• CNC-machined titanium bushings ensure a precise, rattle-free fit every time
• Carbon heat shield integrated for superior thermal management and a purposeful aesthetic
• Available in two finishes: Carbon (H35A-T91C) and Titanium (H35A-T91T)

Build Quality and Materials

SC-Project's Italian craftspeople combine racing-derived fabrication techniques with materials chosen for their mechanical properties first and their looks second — though the result happens to be stunning. The titanium collector features welded segmented bends that optimise exhaust gas flow without the turbulence introduced by mandrel bends alone. CNC-machined titanium bushings are machined to tight tolerances so fitment to the CBR 1000 RR-R SC82 is exact, with no shimming or modification required.

The carbon end cap is produced via hydroforming, a process that yields consistent wall thickness and a smooth internal surface — both critical for predictable acoustic performance. A carbon heat shield wraps the silencer body to protect surrounding bodywork and keep radiated heat away from the rider and airbox.

Performance and Weight Saving

The SC1-R is not merely a styling exercise. Back-to-back dyno testing on the CBR 1000 RR-R demonstrates a gain of +2.9 hp at 13,300 rpm and +3.5 Nm of torque at 3,800 rpm, sharpening throttle response precisely where it matters most on a Superbike. The complete silencer assembly tips the scales at just 2.3 kg — a saving of 0.8 kg over the stock unit at 3.1 kg — contributing directly to improved power-to-weight ratio and more agile handling balance.

Sound

The SC1-R produces a deep, purposeful exhaust note calibrated through SC-Project's internal damping geometry. With the dB killer fitted the measured output is 101 dB at 5,500 rpm — strong and characterful. Remove the dB killer and the silencer opens up to 105 dB at 5,500 rpm, delivering the unfiltered MotoGP soundtrack the Fireblade's engine deserves on circuit.

This silencer is developed for racing use and is not road-legal. It is intended exclusively for closed-circuit competition.
