You are asking a LOT! The People that build the Pipes spend a Ton in time, testing and money to come up with the answers. The stock system is a 4-2-1 note the Splitter plate in the middle of the tube before the Muffler is the 2 section! The 4-2-1 must be the best design because as difficult as it is, everyone is now making a 4-2-1 Sidewinder where they ALL Made 4-1 prior to Hindle / Brock Davidson making the 1st 4-2-1
The longer the 2 section the more help in the midrange
