One of the essential components for vehicle processing, specially designed to give the engine an excellent increase in power at medium and high revs. Thanks to the sophisticated systems available to our technicians and decades of experience in the design and production of mufflers Malossi created this masterpiece. The new MHR muffler for Vespa ET3, specially designed for coupling with our MHR cylinder kit, allows the achievement of the highest power at the same speed, placing itself in the range of the best performing mufflers in circulation. The huge advantage of this exhaust system lies in the particular route calculated and designed to allow it to be assembled WITHOUT HAVING TO CUT THE BODY and keeping the central stand. In any operating configuration and position of the crankcase, this muffler fits inside the vehicle without any harmful contact points that oblige the user to modify the frame of his dear Vespa. The counter-cone has been split to further increase the range of use, reaching a performance gain of even more than 1 HP at the highest rpm when normally the engine drastically loses performance once the maximum power speed has been exceeded.
