9.5 x 7 Trapezoid, 18" Length, 3" Bore, Centre to Twin S957TRAPEZOID157

9.5 x 7 Trapezoid, 18" Length, 3" 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.
