Could you guys answer a question about header length? What would be an aproximate length to start experimenting with on a single cly engine of 87cc displacement. I don't really care about a tuned can, but I want quiet with as little loss of power as practical. This cannister setup is going on a scratch built 35% Extra. The can I'm building is 3.5"dia x 12" long 1.25" inlet. I'm not sure of the outlet dia yet, and also could use a suggestion here too.
Thanks,
Bob
