14 x 8 Oval, 16" Length, 2.5" Bore, Twin to Twin 302397

14 x 8 Oval, 16" Length, 2.5" Bore, Twin to Twin. A twin to twin configuration, otherwise known as a dual, refers to a silencer that has two off-centre exits on one end and two off-centre exits on the other end so the exhaust gases run in two parallel channels before reaching two seperate outlets. This configuration allows you to continue the channel of two seperate lengths of tube and is a very quiet silencer overall. Ideal for duplex systems.
