SC Project SC1-R Titanium Exhaust (250 mm) for RSV4 (2021-24)

The SC Project SC1-R Titanium Exhaust (250 mm) for RSV4 (2021-24) is a racing slip-on muffler for the Aprilia RSV4. SC-Project developed the SC1-R through its work with Aprilia Racing and SC-Project Race departments. The short 250 mm configuration gives the exhaust an aggressive and sporty appearance. It also uses a titanium body, carbon fibre end cap, and titanium link pipe. This exhaust is for racing use only. Visit our website for more products Dirt Street.

SC1-R Racing Design

The SC1-R sits at the top of the SC-Project range for performance and technical solutions. Its development involved close work between Aprilia Racing and SC-Project Race departments.

The compact 250 mm silencer creates a short and aggressive shape. In addition, the exhaust uses an exclusive titanium valve system. SC-Project developed this valve system for MotoGP and WSBK exhausts.

The end cap uses carbon fibre with a rhomboidal and asymmetric shape. Meanwhile, the outer body is available in titanium or carbon fibre. This product configuration features the titanium outer body.

Performance and Weight Reduction

The SC Project SC1-R Titanium Exhaust (250 mm) for RSV4 (2021-24) provides strong performance gains. With the dB-killer installed, it delivers +7.2 hp at 7750 rpm. Torque increases by +6.5 Nm at 7750 rpm.

Without the dB-killer, the power gain reaches +9.1 hp at 8000 rpm. Torque gain also increases to +8.0 Nm at 8000 rpm. Furthermore, the supplied information states that the performance benefit remains usable across the range from 3,000 to 13,000 rpm.

The exhaust weighs 2.3 kg. In comparison, the stock exhaust weighs 5.6 kg. Therefore, the SC1-R reduces weight by 3.3 kg, or around 59% compared with the original exhaust.

Titanium Valve System

The SC1-R features an exclusive exhaust valve made from titanium. The valve system works with the original control unit and wiring. Therefore, the installation remains plug and play.

No ECU remapping is necessary. Moreover, the kit includes the titanium exhaust valve and a full titanium link pipe.

Race-Track Sound

The SC1-R produces 105 dB at 6500 rpm with the dB-killer installed. Without the dB-killer, the sound level reaches 109 dB at 6500 rpm.

The dB-killer is removable for race use. The exhaust uses a hydroformed exit pipe. In addition, its carbon fibre end cap adds to the racing-focused design.

Quality Construction

SC-Project uses T.I.G. welding in a protected environment for the SC1-R. The silencer also features sound-absorbing material that resists very high temperatures.

Furthermore, the insert bushings use CNC machining. These production details complement the titanium construction and technical design of the exhaust.

Complete Racing Kit

The kit includes a specific carbon fibre heat cover. It also comes with a racing bracket for removing the passenger footpeg.

Additionally, the kit includes the titanium exhaust valve and full titanium link pipe. The bracket uses the specified mounting system for installation.
