i have a FMF megamaxi 2, what would be the best way to run it?

[99'300EX]

right now i have a core, and 11 discks with the end cap, is that the best way to run it? or should i run it with nodiscks/no endcap?? please help

I had a MegaMaxII on a Yamaha WR400 dirtbike.....more discs...more top end...less more bottom.....quieter with less discs...i ran 8 discs with the FMF head pipe....too loud though even with the "quiet core" insert

If sound/loudness is not a problem then don't run the quiet core it cuts power.I always run the discs in mine
