I am picking up a white bros. pipe today for my predator.. I would like to know how some of the other predators are running thiers pipe.EX.. how many slip disc are you using the noise reducer in front or back... rejetting ??? thanks blkbird

 

I think most are running all the discs, along with the quiet core. You can order an additional disc kit. Each pair of discs adds about 1-2 DB of sound, so be careful if you ride in a noise sensitive area. If you modify the inlet air, you'll probably need to jet up a bit.
