Eurohorses Do you have Active Sound disabled? When I went to the Turner race exhaust (muffler delete) I had a lot of drone, until I had the Active Sound disabled, then it was greatly reduced. When my dealer updated my sw, which re-enable the Active Sound, the drone was super noticeable again.
Also why on earth are you driving around under 2000 RPM
I mean sure from a stop you have to go THROUGH 1k-2k, but driving around 3k+ is the place to be
