More discs= louder, leaner mixture, less back pressure
One time I was running 10 discs in mine (single 4-1 Supertrapp) and all was good for the type of roads in my area. When I reached the twisty roads in NC, I found that I needed more low end grunt. I ran 5 discs increasing back pressure, which gave the bike better low end. You'll find out later that adding and removing discs will change your plug color. Supertrapp, A+ for tunability.
