The Gibson Patriot Skull 4" stainless cat-back for 2011–2014 Ford F-150 XLT (3.7L) adds a louder, more aggressive exhaust note and bold styling. Mandrel-bent tubing and a rolled-edge slash-cut tip provide a finished appearance; included hardware and factory-style hangers allow straightforward bolt-on installation. The system aims to balance an aggressive sound with controlled interior drone and carries a limited lifetime warranty.
