DescriptionThe whole story▼

Born from SC-Project's development programme for the Trofeo Aprilia Racing RS 660, the CR-T 2-1 full exhaust system brings genuine race-department engineering to your road or track machine. Variable-diameter TIG-welded headers feed the iconic CR-T silencer for a power delivery and soundtrack that no slip-on can replicate — all while shedding 3 kg against the standard system.

Key Features

  • Race-proven 2-1 architecture developed directly for the Trofeo Aprilia Racing RS 660 championship
  • Variable-diameter TIG-welded connections maximise torque across the rev range
  • Significant 3 kg weight reduction over the OEM system for sharper handling and improved power-to-weight
  • Iconic SC-Project CR-T silencer delivers an unmistakable, competition-grade exhaust note
  • Catalyst-free design optimises exhaust gas flow and reduces under-seat temperatures
  • Compatible with the original pillion footpegs — no compromise to passenger practicality

Construction and Finish

The full header assembly is fabricated from AISI 304 stainless steel, chosen for its resistance to heat cycling and long-term corrosion resistance even under sustained track use. TIG welding throughout ensures consistent, gas-tight joins at every junction. A carbon fibre heat shield is fitted to the collector area, providing thermal protection while adding a visual cue straight from the pit lane. Your choice of CR-T silencer — natural carbon or titanium — lets you match the system to your bike's aesthetic without sacrificing a single horsepower.

On Road and Track

Removing the factory catalytic converter and replacing the entire exhaust path with this free-flowing 2-1 system allows the RS 660's parallel-twin to breathe properly. The result is a more responsive throttle, a fuller mid-range, and a top-end that feels noticeably liberated compared to the standard setup. The 3 kg mass reduction sits low and central on the chassis, contributing to more neutral handling — a benefit you will feel from the first corner exit. This system is supplied without a dB killer, so the CR-T voice is unrestricted and entirely characteristic of SC-Project's race-developed products.

Important Notice

This exhaust system is designated Racing Use Only and is not approved for use on public roads. It does not carry road-use homologation and removes the factory catalytic converter. Please ensure compliance with local regulations before fitting.
