Re: What is exhaust drone???
It is when they hit a point where it kind of howls like when you blow across the top of a beer bottle. Some times it is steady, some times it resonates up and down. Something to do with the way the sound waves bounce around inside your car.
Funny thing is I had Flowmaster 50 series with no issues. Went to Ultra Flos with an X pipe and now it drones.
