Great find... very informative reading!

Both ARC Fabrication and Burns Stainless recommend a step tube header for max HP R3. Equal length, of course.

Actually I read all 112 pages before telling Wayne he should post the link.

I don't profess to be the exhaust expert... I just forward what not one, but 2 experts I hired are telling me. Both Arc Fabrication and Burns Stainless use proprietary software similar to DeskTop Dyno to determine their recommendations. I gave them my engine specs (including critical cam specs and dynamic compression ratio)... and they both came back with the same equal length stepped tube answer within 1/10" of each other!

no fire works intended

ok,
just thought i would point out what they were saying about unequal length,that's all.just if equal length becomes too much trouble to configure on black & blue, then you certainly have an option open.sure wasn't looking for any fireworks here.
