Never replied cause I never had Akra's but my slip on Yoshi R77s are great and no need to really play with any settings/tune. I don't use the restrictors that came with them as I think they aren't that loud. But then my previous bike had a single system Brock with Alien heads... Damn they were loud and completely illegal lol but never got attention from the plod cause I always tried to look 4 times before making them roar.
