Dinan Drone
I just had the Dinan freeflow exhaust put on my 2011 E92 DCT. I drove it around, and loved it, but then when driving on the freeway noticed drone at 80 mph in 7th gear. It was 80mph at 3200 rpms or so.
I also have the Dinan ECU software installed. Other than that, the car is stock.
It seemed to go away if I shifted to 6th or increased or decreased speed.
I drive on the freeway quite a lot, and this is right in the sweet spot of where I like to park the speed on the freeway.
Does anyone have any advice? Do they all do this and is this just the trade off for getting a sportier exhaust?
I bought the Dinan in large part because I read online that it didn't drone.
Advice welcome... am I just stuck living with this as the downside to having non-OEM exhaust?
