I see a lot about drone, what exactly is drone?

 

It's an exhaust tone / stutter in the engine that some feel, some hear or both. I have it on both my 2012 durnago and my 2009 charger. Stop looking for it if you haven't noticed it yet as once you find it you may fixate on it. Its taken me several years to accept its part of the 5.7litre engine.
