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.

The exhaust is identical to the Stock setup with the exception to the Xlerator VX 13" muffler, 3" Outlet side pipe and 3.5" tip. I am just at a loss right now with all the differing information that I have gotten and don't know which way to go.

Most definitely it is confusing. When i call the different companies, they all just try to sell me their most expensive muffler. The only honest one was the guy at Flowmaster who took the time to tell me that the muffler that the exhaust shop was trying to sell me may or may not eliminate the drone i am getting. After talking to Bill this afternoon, I am going to set my CS back to stock this weekend when i get home to see if it is the canned Level 2 87 Tow setting that is contributing to my issue. If it is I just hope my PHP custom calibration will help eliminate or reduce the magnitude of the drone
