Based on my experience with exhaust engineering and designs, the extra piping length post header/manifold will help slightly for "drone-prone" systems. More influence can come from the proper tuned length of the header manifold exiting the exhaust ports of the engine.
I may have found a system design that works well with the factory exhaust header manifold, but I am not done testing my prpototype to fully confirm this result. I will keep everyone posted.
