12 x 6 Oval, 18" Length, 3" Bore, Centre to Offset. A centre to offset configuration refers to a silencer that has a centre exit on one end and a off-centre exit on the other end so the exhaust gases go round a curve before reaching the outlet. This results in a slightly quieter silencer than a centre to centre and is also useful for moving around protruding parts such as a suspension component.
