The SSI system is not restrictive. That piece of bad information has been spread by dealers of cheap short tube T304 headers. I took a trip out to CA to meet with John/SSI about this system before developing the Y-assembly with M&K and selling them complete. He had pictures and dyno data of a similar twin turbo setup making 600HP. We went through the physics and how the equal length primaries helped off-boost torque as well as top end flow/HP. I used those same principals and applied them to include the secondaries when designing my own headers.
