Classic look 'MaXcone' series mufflers
Italian exhaust manufacturer QD's (Milan) MaXcone series mufflers are designed for those who want a classic look. Seen here on the Ducati Scrambler, the "megaphone" line and the use of polished AISI 304 stainless steel give the MaXcone mufflers an aggressive and elegant character.
The die-cast magnesium end cap with the logo in relief simulates the classic "counter-cone" used in racing motorbikes of the 70s. The end caps of the MaXcone series are designed internally to guarantee maximum performance and phonometric yield, the system used internally includes a perforated barrel with a 5 mm diameter hole with an 8 mm pitch.
The layering of the sound-absorbing material has been designed to give a sound characterised by low frequencies below 800 Hz. At the same decibel level, the timbre of the MaXcone series QD mufflers is low and deep, the best you could ask for to give your motorbike a "voice" with a strong character.
The MaXcone series QD mufflers are equipped with the QD GAS-EXTRACTOR system. This system promotes the flow of exhaust gases by increasing the extraction from the exhaust system - the GAS-EXTRACTOR creates a so-called "pulsation" area which absorbs the pressure waves generated by the engine, lowering the decibel level.
As with all QD Exhaust products, this system is sold with a Service Card that allows the owner to extend to a 30-month warranty programme and to download the European certification.
