10 x 4 Oval, 9" Length, 1.75" Bore, Parallel Offset. A parallel offset configuration refers to a silencer that essentially runs in a straight line from the far edges of a silencer so the inlet will be to the far left of one end and the far right of the other. This configuration is primarily used to "tuck" the majority of the silencer into an existing space on the configuration, which can be particularly useful for builds with a very small amount of workable space.
