2011 F250 6.2
I replaced the just original muffler with the 50 series It gave it a deeper throaty sound I was looking for. In fact it could have been a little louder. You will need to bring about 16" of 3.5 inch exhaust pipe to your local muffler shop for the install. For some reason they don't carry pipe that big
Not as easy as as it sounds
The installation was pretty straight forward. The three sections on the drivers side were a pain in the back side to get lined up properly(which they still aren't)In order for the passenger and driver side to be equidistant from the truck centerline and be level the drivers side actually touches the spare tire. As a result the drivers side exhaust pipe hangs about an inch lower than the passenger side to give me clearance from the spare.
