The terminal of A.M.A. SERIES are dedicated to the American custom motorcycle.

The choice of using quality materials is as always the denominator that unites all the QD production; for this line, as well as to internal components, we have chosen to use stainless steel AISI 304 mirror polished for the body of the silencer and ERGAL S55 for the input and output bottoms.

The terminals of A.M.A. SERIES are designed into them to ensure maximum performance output and sound level meter, the system used inside provides a perforated barrel with a hole diameter 5mm 8mm step. The layering of the sound absorbing material has been studied to give the terminal a sound characterized by low frequencies of below 800Hz.

With the same decibel level the tone of A.M.A. terminals SERIES is low and deep, the best you could ask for to give your bike a “voice” with a strong character.
