Hello, have the Akrapovic Slip on it without DB Eather. Oh that’s hellish loud. I think the green-wise fraction will quickly pull me out of circulation. If the DB Eather is inside it also sounds somewhat kernely. But had the sport DB Eath from summer on it already? It should be a little louder than original but still in the frame… ..mainly you could with the DB Eather the full power from the exhaust hollow,other than with the original DB Eath He. What experiences did you have? Post a message. Bernhold
