3-1 Full Exhaust System Design

This SC Project 3-1 Stainless Steel full exhaust system uses a three-into-one configuration. The design supports improved exhaust flow and complements the 765cc three-cylinder engine.

SC Project developed the system for the Triumph Street Triple 765 R and RS models from 2024 to 2025. It also uses a bracket mounting system for installation.

Performance and Weight Reduction

The system delivers a claimed 6 hp increase at 10,500 rpm. It also provides a claimed 4 Nm torque increase at 10,500 rpm.

Weight reduction is another key benefit. The SC Project system weighs 4.0 kg, compared with 9.6 kg for the OEM exhaust. This results in a 5.6 kg weight reduction compared with the original system.

Therefore, the exhaust removes more than 55% of the OEM exhaust weight. This reduction can contribute to improved agility on the Triumph Street Triple 765 R and RS.

AISI 304 Stainless Steel Construction

SC Project manufactures the exhaust using AISI 304 stainless steel. The same material forms the headers and main exhaust body.

This construction provides resistance and durability. SC Project also uses handcrafted TIG welding during production. In addition, CNC-machined internal bushings add to the detailed construction of the system.

S1 Silencer with Carbon Fibre End Cap

The S1 silencer gives the exhaust an aggressive yet refined appearance. It features a conical shape and an aluminium SC Project logo plate.

The exhaust also includes a carbon fibre end cap. This detail adds a distinctive finish to the S1 system while maintaining its race-inspired design.

Adjustable Exhaust Sound

The SC Project 3-1 Stainless Steel full exhaust system includes a removable dB-killer. This gives riders the option to change the exhaust configuration.

With the dB-killer installed, SC Project records 110 dB at 5,400 rpm. Without the dB-killer, the system records 114 dB at 5,400 rpm.

The conical S1 silencer produces strong and deep exhaust notes. SC Project describes this as its signature sound.

Plug-and-Play Installation

SC Project designed this exhaust for 100% plug-and-play installation. The system uses a bracket mounting setup and includes a single lambda probe.

It is also compatible with the original belly pan. ECU remapping is recommended to achieve the best performance from the exhaust system.

Racing-Focused SC Project Engineering

The system reflects SC Project’s experience in the Moto2 World Championship. SC Project developed the exhaust with a focus on performance, weight reduction, sound, and detailed construction.

The system is marked for racing use only. Riders should consider this specification before purchasing or installing the exhaust.
