The new STR-1 exhaust is the last creation of SC-Project R&D Department and represents a full step forward in terms of tuning process of the new Yamaha MT-09.

To combine perfectly the aesthetic of the bikes originally designed and produced with low-position exhaust – sometimes totally positioned under the engine – it has been necessary to project and develop a new solution: the answer is the new and innovative STR-1 exhaust.

Great attention has been dedicated to performance optimization and sound output, which is a real “must” for the 3-cylinders Yamaha engines and for all SC-Project products.

The full-system for the MT-09 has been manufactured with high-quality stainless steel AISI 304 and with top level quality finishes that this bike deserves. All couplings are guaranteed by male / female bushings that ensure a perfect seal, with special T.I.G weldings handcrafted in protected environment. The option “black color” is made with a special ceramic paint process to resist to high temperatures. The specific carbon fiber cover is manufactured with autoclave process to offer a unique style and harmonic design.

The STR-1 full system for Yamaha MT-09 allows to save 0,5 kilograms and to gain an outstanding maximum increase of 3.1 hp and 2.5 Nm of torque at 9.700rpm (if compared to the original system), with a sensible improvement of throttle response and riding experience throughout the engine delivery range, in the total respect of Euro5 regulations.

The installation is plug&play and ECU remapping is not required.
For racing use only, it is possible to remove the catalytic converter.
The removal of the catalytic converter does not meet the Euro 5 regulations.
