YOSHIMURA offers you this complete exhaust system with double silencer for your YAMAHA YFM 660cc. This exhaust system, called RS4, is sold with a titanium exhaust manifold and a carbon silencer with carbon tip. Why a titanium manifold? Quite simply, because it's lighter than stainless steel, yet just as strong. It has been tested for over 24 months in competition to ensure unrivalled performance and longevity. The diameter of the manifold is specially designed to allow the maximum possible evacuation of your engine. This increases the performance of your motorcycle or quad compared with the original exhaust system. This pack includes a carbon silencer with carbon tip, combining lightness and reliability. The quality of this product is beyond reproach. The finish is excellent. It is FIM-approved.

PHONO NON CONTRACTUELLE.
