I'd say it's pretty similar. The Evolve has a bit of a noise spike, similar but narrower in RPM band, to the Eisenmann Sport with a primary cat delete. The Akrapovic Evolutionis a little bit quieter at 1900 rpm, but louder pretty much everywhere else, except over 6000pm (where they are about the same).
