I have a '99 Evo with an EV27 cam, Screamin Eagle intake, K&N filter, Mikuni carb, and Screamin Eagle ignition. I'm putting a 2-into-1 header on it and a single Supertrapp "universal" fishtail muffler that uses discs.

Is there a general rule or suggestion regarding how many discs I should install in the muffler?

I'm more interested in low-end torque rather than high-end horspower.

With your upgrades you should be able to run all 18 discs supplied with the pipe.
