IMO the akra evo is one of the best exhaust systems in the market, very civilized at low rpm's, very agressive sound at high rpm's without any drone, very noticeable hp gain due to high flow cats
Havent heard any Eisenmann exhaust, I had a BMW performance exhaust before the akra evo and dont regret having replaced it with the akra
