Mounted on 12' F150 5.0. Very happy with this silencer! Installed Midas (hour and a half). The installer moved the muffler about 2 inches from the original's location and relocated the exhaust pipe forward of the muffler toward the crampons to reduce noise inside the truck. I had a Mustang 07 GT prior to this truck and honestly this muffler made the exhaust sound better and louder than my stock Mustang exhaust.
