Who all has the white bros. exhaust and how do you like it? I just ordered one today and would like to know how many disc does everyone use?

 

i was running 4 and the q-core till it broke i think i have more lowend without it but it did sound better

 

I just left the stock 6 or 7 plates in there, didn't notice any power increase (no re-jetting recamended) but it sounds and looks cool.
Might have helped on top end.

when I had it on my sp400 I think I ran 6 discs. I had a quiet core in there but it broke, disappointing after you pay $35 for it and then it breaks after a few rides...

It was overly loud for me and I had 3 screws break off while I was using no-seez on them.
