DescriptionThe whole story▼

Race-only and proud of it — the SC-Project Titan CR-T full exhaust system was developed specifically for the Aprilia Racing RS 660 Trofeo and carries that competition pedigree into every weld, every CNC-machined titanium sleeve, and every note of its 115 dB soundtrack. This is not a road-legal silencer with a sticker on it; it is a purpose-built 2-1 full system engineered to the same standard as MotoGP hardware, and it is approved for track use only.

Key Features

  • Race-use only — no road approval; designed from the ground up to meet competition requirements rather than road-going compromises.
  • 100% titanium headers with T.I.G.-welded seams and CNC-machined titanium collars for maximum structural precision and heat resistance.
  • Dramatic mass reduction: the SC-Project system weighs just 2.4 kg against the stock unit's 6.4 kg — a saving of 4 kg from the chassis.
  • Measured performance gain of +2.9 hp and +2.6 Nm at 8,000 rpm across the entire rev range, not just at the peak.
  • Unmistakable CR-T race sound rated at 115 dB at 5,250 rpm — audible, intentional, and entirely at home on circuit.
  • Available in two finishes: natural titanium or carbon fibre canister, both sharing the same titanium 2-1 header construction.
  • Lambda sensor provision included; no dB killer fitted.

CR-T Engineering — Built for the Trofeo, Ready for Your Track

The CR-T designation sits at the top of SC-Project's competition catalogue, and the Titan variant for the RS 660 illustrates exactly why. The 2-1 collector configuration concentrates exhaust gases efficiently, delivering the torque and power improvements in the mid-range where circuit riding demands them most. Every joint is T.I.G.-welded by hand, and the CNC-machined titanium sleeves ensure a repeatable, airtight assembly that survives the thermal cycles of an endurance session as confidently as a sprint race.

The single-seat exhaust bracket included in the kit gives the system a cleaner visual line at the tail, stripping away the visual weight that comes with passenger-centric mounting solutions. Installation is direct plug-and-play for the RS 660 — no fabrication, no custom mapping adapters beyond standard ECU recalibration that any serious track bike should receive after an exhaust upgrade.

Important Safety and Legal Notice

This exhaust system carries no road-going type approval and must not be used on public roads. It is designed exclusively for closed-circuit competition and track-day use. SC-Project and Inter-Pace strongly advise that the pillion footpegs are removed before fitting, as they are not compatible with the single-seat mounting bracket supplied. Always comply with circuit sound regulations before entering the pit lane.
