HEADER INSTALLATION INSTRUCTIONS FOR
2011+ FORD F-150 5.0L 145” WHEELBASE
Thanks for purchasing Stainless Works Muscle Flow Headers for your Ford F-150 5.0L.
We have gone to great pains to make sure that our exhaust systems fit and sound great.
Please follow these steps to ensure that your installation goes as planned.
1. Stainless Works recommends the use of Hi-Temp RTV silicon gasket maker as an
option to or in conjunction with the use of factory gaskets. The recommended
RTV is Valco Sensor-Safe aluminum All-in-one or Permatex P/N 101BR,
available at NAPA and other retailers.
2. Disconnect the battery before starting work on the exhaust system for your
vehicle.
3. Your exhaust system can be installed by a weekend warrior but the use of a lift is
recommended for ease of installation. If using a jack, the vehicle must be placed
on a level hard surface and jack stands are required for safety reasons.
