INSTALLATION INSTRUCTIONS FOR 2011+ MUSTANG GT 5.0
HEADERS AND LEADPIPES – P/N M11HDRCATX/ M11HDRORX


Thanks for purchasing Stainless Works Muscleflow Headers for your 2011+ Mustang GT
5.0. 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 Permatex Hi-Temp RTV silicon gasket

maker as an option to or in conjunction with the use of factory gaskets. The
recommended RTV is Sensor-Safe P/N 101BR or 27BR, available at NAPA and
other retailers.

2. Disconnect the battery before starting work on the exhaust system for your

vehicle. Reconnect the battery when the job is completed.

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.

4. Raise and support vehicle.
