You are correct Sir about balancing the pulses for a little gain.
Back in the "old days" (some of you may remember this) with true duals we spray painted both exhaust pipes from the header/manifold flange back, cranked and ran it until hot, then placed the H-pipe where the paint had quit peeling off. Now I'm really showing my age.
