8 x 5 Oval, 12" Length, 2.5" Bore, Centre to Twin 101638

8 x 5 Oval, 12" Length, 2.5" Bore, Centre to Twin. A centre to twin configuration refers to a silencer that has a centre exit on one end and two off-centre exits on the other end so the exhaust gases go through a Y Piece before reaching the outlet. This configuration allows you to merge the gases from two seperate tube routes into a single outlet, or expand a single tube route into a dual section. We are often able to make the outlet diameter different to the inlet diameter; please select this as a product option when ordering.
