Is this the same length as factory muffler and does it have the same size inlet as the resonator pipe which goes into the muffler? How about length of muffler.


  • The Gibson MWA Superflow Offset/Center Oval Muffler has an inlet/outlet diameter of 3 inches which may mount to your factory F150 exhaust depending on the year and model. However, it is designed for universal fitment, and will not be an exact match for all 97-17 F150s.
