APRILIA TUONO 660 (2025-2026) 2-1 Titanium full exhaust system, with S1 titanium exhaust, with welded sector link pipe

The look is simply astonishing: the handcrafted TIG welds on the spectacular titanium S-shaped link pipe, the tapered shape of the S1 titanium silencer, the high quality carbon fibre endcap and the elegant SC-Project lasered logo on the muffler’s body, are authentic technological masterpieces.

Everything has been developed to offer an incredible performance improvement together with a great upgrade of the agility of the Aprilia Tuono 660, thanks to an outstanding weight reduction of -40% (if compared to the OEM exhaust system) and a power boost of 3,1 hp at 10000 rpm and 3,1 Nm at 6500 rpm. The variable size titanium headers are specifically calibrated to improve torque and power delivery, especially in the low and mid RPM range.

From the huge outlet of the S1 muffler, the voice of the Aprilia twin cylinder will be simply unforgettable, with a dark and loud tone and 114 dB at 5250 RPM of pure racing music.

The installation is completely plug and play and it’s completely reversible. ECU remapping is not required.

This product does not meet European regulations for road use.

Together with this kit, the purchase of SC-Project ECR (Electronic Catalytic Remover) is strongly recommended. With the removal of the catalytic converter, the Tuono 660 ECU will generate an error that can cause different issues while riding. This crucial 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.
