e series disc question

[400ex00]

my 400ex has a stage 1 hot cam, e series slip on, stage 2
jet kit, 11:1 Wiesco piston and a 14 tooth front sprocket.
i was wondering if anyone knew the exact number of discs
i should be running in my exhaust. i was thinking maybe tr-
ing around 15 to start with and go from there. does anyone
know about or done this before. thanks.
