A.M.A. SERIES Slip-Ons are dedicated to custom American motorcycles.
As always, the decision to use high-quality materials is the common factor that characterizes all of QD's products; for this line, in addition to the internal components, we decided to use mirror-polished AISI 304 stainless steel for the body of the silencer and ERGAL S55 for the entrance and exit caps.
The interiors of A.M.A. SERIES Slip-Ons are designed to provide the maximum performance and phonometric yield; the interior system consists of a perforated tube with 5-mm holes 8-mm apart. The stratification of the sound-absorbent material has been designed to give the Slip-On a sound characterized by low frequencies under 800 Hz.
At the same decibel level, the tone of A.M.A. SERIES Slip-Ons is low and deep: what more could you ask to give your motorcycle a “voice” with a strong character.
