I got my new MagnaFlow today. Had them cut out the factory exhaust and replace it with a new muffler (single 3" in/out). Come to find out the 3" fits the head pipe but have 2.5" in the back. There is a huge drone inside the cab. Has anyone done this? Do you have the same drone?
I am thinking about replacing the tail pipe with a 3" to see if it sounds any better. Overall, the outside sounds good.
