INSTALLATION INSTRUCTIONS FOR 2011+ MUSTANG GT AND
2011-2012 GT500 CHAMBERED MUFFLER CATBACK EXHAUST –
P/N M12CB3/ M12CB3HDR
Thanks for purchasing Stainless Works Chambered Muffler Catback Exhaust for your
2011+ Mustang GT 5.0 or 2011-2012 GT 500 5.4L. 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. Please assemble everything together
loosely, make fitment adjustments then tighten everything in sequence.
1. Disconnect the battery before starting work on the exhaust system for your
vehicle. Reconnect the battery when the job is completed.
2. 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.
3. Raise and support the vehicle.
4. Loosen clamps on mufflers and remove from the car.
5. Loosen two clamps at back of H-pipe, remove pipes and retain these clamps for
use with the Stainless Works system.
6. Using factory clamps from above, install front longer set of chambered mufflers.
If catback system is made with 3” dia. inlets, it is designed to fit with our
Performance Connect Stainless Works X-pipe, which has 3” OD outlets, and 3”
clamps are supplied with the X-pipe.
7. Install front tailpipes with (2) 3” clamps.
8. Install rear tailpipes with (2) 3” clamps.
9. Install hanger clamps and shorter rear chambered mufflers.
