I have a 02 ultra, which I've dropped a new SE 43/8 in. biult the top end with WT forged heads, WT 26g cams, 57mm tb, fatcat 2:1. I've taken a new SE night stick and had the inlet cut-off, belled to fit the fatcat outlet. I know how hard this 103 breathes, so since the night stick came with 10 disc plus closed end cap. I put another 9 disc, for a total of 19 disc+ closed end. Does this sound close enough to be safe till it can be tuned. Thanks forward, Gene
