    Default 100" motor- 2" collector

    I just got a 2:1 supertapp. It has 1 3/4 headpipes flowing into a 2" collector. Will this system flow enough for a 100" motor that is limited at 5700 RPM? It will rarely be run over 5000 RPM.
    Also, it came with an open end cap and 6 disks, which I suspect is not enough. How many discs should I be running?

    The pipe should perform well on a 100" motor; however I would look at picking up another 6 pack of discs for tuning purposes/more flow.

    Thank you very much for your reply. I thought that more disks were needed. I'm planning on keeping the open end cap, so all I really need is 6 more disks?
    Thanks again.

    With the open end cap (=10-12 discs) + 6 + an additional 6 is equivalent to 22-24 discs and a closed end cap. That should be more than enough for tuning purposes
