How do you plan on routing the exhaust? If you dump underneath the vehicle you will get drone. If you run it out the side like stock or at a 45˚ you'll have much less drone. I'm sure position of the muffler along the length of the exhaust will make a difference as well but I dont have anything besides guesses at how that might effect it.
