INSTALLATION INSTRUCTIONS FOR 2013+ SHELBY GT500
CATBACK - P/N M13GT/ M14GT
Thanks for purchasing a Stainless Works Catback for your 2013+ Shelby GT500. 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 sensor safe silicon gasket
maker as an option to or in conjunction with the use of factory gaskets. The
recommended Oxygen Sensor Safe RTV is either Valco All-in-One Aluminum or
Permatex Copper P/N 101BR available at NAPA, Autozone 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. You will assemble the components together as specified below, but only snug the
clamps as you move along from front to back. When placing the X-pipe into
position, make certain that you push it fully forward and level it in with the
vehicle. After aligning all the components in the vehicle, you will tighten all the
clamps working from front to back of the vehicle.
5. Disconnect battery.
6. Raise and support vehicle.
7. Loosen clamps at mufflers.
8. Loosen double clamps at factory connection point and remove tail pipes saving
double clamps for installation.
9. Remove mufflers.
10. Install retro chambered dimpled mufflers using double clamps from factory
exhaust.
