SC-Project used all the experience gained during the long-term collaboration with Aprilia Racing to develop this full exhaust system with an S1 muffler for the new Aprilia RS 457.

Everything has been developed to offer the best performance together with a great improvement of the agility of the Aprilia RS 457, thanks to an outstanding weight reduction of over 30% (if compared to the OEM exhaust system) and an incredible performance gain of 2.5 hp at 7200 rpm and 2.2 Nm at 7200 rpm (performance data are registered without dB-killer).

Together with this kit, the purchase of SC-Project ECR+ (Electronic Catalytic Remover) is strongly recommended. With the removal of the catalytic converter, the bike’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.
