It combines SAE 304 stainless steel headers with a CR-T titanium exhaust, including a titanium end cap. The system produces a stated increase of +2.9 hp at 8000 rpm and +2.6 Nm at 8000 rpm. In addition, its stated weight is 3.4 kg compared with 6.4 kg for the stock system. Visit our website for more parts and accessories of Aprilia.

2-1 Full Exhaust System

This full-system exhaust comes from research, development, and design work by the SC-Project R&D department for the Aprilia Racing RS 660 Trophy. The complete system was designed for the Aprilia RS 660 and uses a 2-1 Full exhaust system configuration.

Furthermore, the system remains compatible with the original lambda probe. It also uses technical solutions such as TIG welding performed in a controlled environment and CNC-machined billet bushings.

Stainless Steel Headers and CR-T Muffler

The headers use SAE 304 stainless steel and feature variable sizing. According to the supplied overview, these headers provide an increase in torque and maximum power throughout the curve.

At the rear, the system uses the CR-T muffler, which is available in titanium or carbon versions. This specific product uses a titanium body and titanium end cap. The CR-T also gives the exhaust its unmistakable sound, described in the supplied overview as a hallmark of the SC-Project range.

Power, Torque and Weight

The SC Project 2-1 full exhaust system provides the following stated technical figures for the Aprilia RS 660 (20-24):

• Power: +2.9 hp @ 8000 rpm
• Torque: +2.6 Nm @ 8000 rpm
• Weight Difference: -3 kg
• Stock Weight: 6.4 kg
• SC-Project Weight: 3.4 kg

Therefore, the stated figures show a 3 kg difference between the stock and SC-Project system weights. The supplied overview also states that reducing the kit weight guarantees better handling of the bike.

Lambda Probe and Racing Specification

The exhaust is compatible with the original lambda probe and includes a lambda probe specification. It uses a Bracket mounting type and does not include a dB-killer.

Moreover, the product is identified as FOR RACING USE ONLY. The supplied specification records 114 dB @ 5250 rpm. The system is also compatible with the original passenger pegs.

The supplied notes recommend ECU remapping to obtain the best performance. The overview also states that removing the original catalyst allows an important reduction of operating temperature.
