I talked to Steve before doing the ITB upgrade. He said my much earlier and flatter torque (notably higher than the graph below and something I really like) plus a limited higher end for numbers is the SSI signature. The caption for this dyno graph just said headers (not SSIs specifically) and going by what Steve said I would be they are not SSIs.

Looking at this dynojet graph, you're down about 27whp.
