10 x 4 Oval, 12" Length, 2" 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.
