After a few days of driving with the Invidia, I learned to minimize droning through controlling the accelerator and through shifting. It's not that bad after you learn how to do this. I love the Invidia's rumble down low and fierce roar up top. When it's brand new, the sound is alot more crisp and defined but that goes away in a day or two. Every week or so I just run a strong stream of water into each muffler and it sounds like brand new again.
