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!
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.
