SC Project SC1-R Titanium Stainless Steel full exhaust System For Aprilia RS 660 (2020 Onwards)

The system uses AISI 304 stainless steel headers with variable dimensions. Experts calibrate these dimensions. This ensures they maximize power and torque across the entire RPM range. The headers then join the SC1-R muffler, the system’s key component.

The manufacturer often offers the muffler body in titanium. This material is renowned for its lightweight properties and high heat resistance. SC-Project designs the muffler with an aggressive, taut profile. Its aesthetic highlight is the distinctive asymmetrical, rhomboidal carbon fiber end cap. They form the outlet pipe via a specialized process called hydroforming.

The construction quality is premium. SC-Project incorporates T.I.G. welding, performed in a controlled environment. They also use CNC-machined billet bushings. These meticulous details ensure impeccable coupling, easy assembly, and long-term durability. This reflects SC-Project’s racing pedigree as a technical supplier for top-level motorcycle competitions like MotoGP.

This full exhaust system offers notable performance gains over the stock unit. The racing versions remove the original catalytic converter. For these versions, riders can see significant performance boosts. These are sometimes quoted as high as $+3.6\text{ hp}$ and $+2.7\text{ Nm}$ of torque at 9250 rpm. Additionally, removing the original catalytic converter reduces the operating temperature. It also contributes to a considerable weight reduction—often around $2\text{ kg}$ lighter than the OEM system
