Spend a little time this weekend playing with the induction set up and am going to trial an open filter configuration as shown in the picture. It’s going to be the most free flowing and highest induction roar, though most susceptible to heat soak. I’m going to see how I get on over next week or two and report back.
Initial thoughts are it sounds good and seems to pull harder at the top end, with no noticeable reduction throughout the Rev range, hard to tell though as I love the sound!
