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
Required Removal of First Baffle plate in Pump
Recommend Drilling second baffle holes to 7/16″ to meet flow requirements
Recommend Widening of Pump Exits to 24mm wide to meet flow requirements
Recommend Port matching all exhaust parts that bolt together including the exhaust base and Diffuser
