5 or collectors you kind if don't have a choice but 6generally don't work as well as 6-2:1. That was the recommendation from burns stainless amd the simulator said the same.....the area at the merge is just too big. Its not a huge difference but it's real.
Thanks. My plan is to do 6-3-1 with fairly long primaries, because that gives me 3 360° pairs, which I think has to help scavenging.
My question is more about what you think of that vortex shape. I feel like it can only help with both flow velocity and sound, but that's just gut feel. I'm curious if you think it's just for show or if it could have some benefits.
The vortex thing looks like nonsense. For sure it creates a flow restriction.....I can't see anything else it does?
On the header layout I'm not sure if a 6-3-1 has any advantages over a 6-2-1? It is a bit heavier but either way what you are getting over a 6-1 is better collector ID and additional tuned lengths. I would need to play with it on the simulator to see if 6-2-1 beats 6-3-1....I'm skeptical but ill look at it if I escape being trapped in AZ and make it back to PA.....it rained so flight canceled.
