YAMAHA MT-09 (2025) EURO5+3-1 Stainless steel full exhaust system, with S1 stainless steel exhaust

The S1 silencer shape donates an aggressive yet elegant look to the full system and is enriched by the elegant SC-Project laser-engraved logo.

As soon as you start the engine on your Yamaha MT-09, the conical shape of the silencer will reward you with dark and deep notes, true SC-Project signature sound.

To guarantee you the best customization possible, we have equipped the muffler with a removable baffle. This solution will give you the choice between 107 dB at 5000 rpm with dB-killer installed and a louder sound of 113 dB at 5000 rpm without dB-killer.

The exhaust system is crafted entirely with AISI 304 Stainless Steel to ensure optimal resistance and durability. It is 100% made in Italy using state-of-the-art technologies, exactly like every single SC-Project product.

The installation of the kit is completely plug and play and it’s completely reversible. ECU remapping is recommended to obtain the best performance.

Together with this kit, the purchase of SC-Project ECR (Electronic Catalytic Remover) is strongly recommended. With the removal of the catalytic converter, the motorcycle’s ECU could generate an error. This device has been developed by SC-Project to correctly manage the removal of the catalytic converter. Extremely easy to install, it needs to be connected to the OBD socket and it will automatically manage the error, safely restoring the correct functionality of the on-board electronic system.
