I absolutely hate drone! On one of my cars I switched the mufflers 4x and finally ended up with zero drone with a turbo type muffler.
Most guys don’t want to switch to a turbo style muffler for fear of HP Loss, I’ll gladly loose 10hp for no drone.
Check out this video, also take a look at Roadster Shops build gallery you’ll see they are adding these to every car.
