8 x 5 Oval, 16" Length, 2" Bore, Triflow (CO, TRI) 105329

8 x 5 Oval, 16" Length, 2" Bore, Triflow (CO, TRI). A triflow configuration refers to a silencer that uses a complex internal chamber. The flow essentially goes through the length of the silencer three times in total before exiting via the outlet, providing a huge amount of sound and vibration dampening while still being a free-flowing setup. This silencer configuration is about as close to OEM in terms of volume as we tend to achieve.
