DescriptionThe whole story

The SC-Project GP-22 is not an interpretation of MotoGP technology — it is the exact exhaust system raced by Aleix Espargarò and Maverick Viñales on the Aprilia RS-GP during the 2022 MotoGP World Championship, now made available for the RSV4 1100 Factory. Developed in direct collaboration with the Aprilia MotoGP Factory Racing team and hand-built from a specialist titanium alloy in Italy, it is the lightest and most exclusive racing exhaust SC-Project has ever produced for a production motorcycle.

Key Features

  • +6 hp and +6 Nm of torque at 8,000 rpm over the stock system — a genuine, measurable performance gain on track
  • Saves 5.1 kg compared to the standard exhaust (GP-22: 500 g vs. stock: 5,600 g), transforming the RSV4's agility and handling balance
  • 122 dB at 6,500 rpm — no db-killer, no compromise; pure, unfiltered MotoGP acoustics for closed-circuit use
  • 100% hand-welded full-titanium construction using the same alloy and techniques as the Aprilia Racing factory exhaust systems
  • Titanium link pipe included for optimised exhaust gas flow from collector to silencer
  • Dedicated mounting bracket engineered for maximum stability under sustained high-rpm racing loads

MotoGP-Derived Construction

Every GP-22 is fabricated by the same SC-Project technicians who build the race exhausts for Aprilia's MotoGP programme. The choice of a specialist titanium alloy is deliberate: the material offers an exceptional strength-to-weight ratio and outstanding heat resistance at the extreme exhaust gas temperatures generated by the RSV4 1100's V4 engine at full chat. All joints are hand-welded for precision fit and gas-tight integrity — there is no production-line shortcut in this assembly process.

The result is a slip-on silencer that weighs just 500 grams. On a bike that already handles with surgical precision, removing over five kilograms from a high, rearward mass position sharpens turn-in response, reduces unsprung and rotating mass effects, and gives the rider a noticeably more agile, point-and-shoot character — exactly what a track day or club racing environment demands.

Sound & Track Presence

At 122 dB measured at 6,500 rpm with no db-killer fitted, the GP-22 delivers the aggressive, bark-and-crack sonic character that defines the Aprilia V4 at full throttle. This is a racing exhaust built for closed circuits only — the sound level is part of the engineering intent, projecting that unmistakable MotoGP note that is immediately recognisable in the pit lane. If you have heard an RS-GP at close range during a 2022 race weekend, you already know what to expect.

Fitment & Compatibility

The SC-Project GP-22 (part number A27A-GP22-R) is a direct-fit slip-on exhaust system designed exclusively for the following model:

  • Aprilia RSV4 1100 Factory — model years 2021, 2022, 2023, 2024

The included titanium link pipe ensures a correct, leak-free connection to the existing headers. No modification to the standard collector is required for installation. This system is for racing and closed-circuit use only; it does not carry road-legal homologation and must not be used on public roads.

What's Included

  • GP-22 slip-on silencer in titanium
  • Titanium link pipe for optimised exhaust flow
  • Dedicated mounting bracket for maximum stability
  • Springs and bolts for secure installation
  • SC-Project decal set
