WB FLOWMAX Wetbike exhaust plate

The WBW FlowMax Exhaust Plate replaces the OEM banana plate with a properly engineered transition between the engine outlet and expansion chamber diffuser.

By increasing the internal flow area to approximately 2.9 in² and maintaining a smooth even flow path, the FlowMax improves exhaust flow while eliminating the turbulence created by spacer-based modifications. Additional material allows the plate to be port matched up to 3.14 in² for modified engines and larger diffusers.

Use this with other modifications to achieve more RPMs, Power, top speed etc. the flow plate is your foundation for exhaust flow
