Seen during our coverage of the World Championships in Houston, O.S. Speed have released further details on their new line of on road exhaust systems. These new exhausts are fixed to the manifold with a pair of aluminium clamps which prevent the silencer from disconnecting during races. Unlike conventional spring connection, the semicircular clamps enable the adjustment of the pipe to any direction. The pipe itself makes the low to middle range response of the engine more snappy while maintaining top speed power. Available for the .21 (FEMCA & IFMAR legal) and .12 (EFRA & IFMAR legal) engines.
