No, not augers. I was really looking at function vs. cost - just looking for the most flow and lowest achievable DB. Its hard to explain until you hear them in person. We did one car with augers, another group of guys did the chambered ones, and the ones I have from SS are a simple and highly functional design. Much more freeflow than augers and a completely different design. When people see them they cannot believe its not super loud. Same principal as chambered but using expansion and contraction of air chambers vs. restrictive baffles with louvered vents or spiraled augers.
