I also have a question for you about header design and modeling. I want to do a 6-3-1 for my bike - do tools like Dynomation and PipeMax let you model specific exhaust layouts like that and experiment with different primary, secondary, and final length/dia? I paid for a design consult with an engineer but some of what he came up is hard for me to reconcile with the bit of theory and practice that I know, so I'm looking for a second opinion. Something I could play with and see curves going up and down would be ideal, provided the results could be trusted...
I had an old copy of pipemax, it will spit out what it thinks is the optimal tri-y, which could be 6-3-1 or 6-2-1, kind of doesn't matter for flow but will change sound which is what you're after.
Kind of the same with dynomation but while dynomation will make a suggestion it runs whatever you say you have.
Pipiemax doesn't understand the tri-ys i build from the burns stainless design, dynomation doesnt suggest it but has no problem analyzing it. Pipe max did tell me 2,3,4 harmonics stuff that helped me understand stand what Burns did.
Long story short, I can run a few options for you.
