Exhaust System Installation
Cat Back Exhaust System
Dual Rear Exit w/ 4.5” Pro-Series Tips
2015 Ford Mustang GT 5.0L V8
PN 14328(BLK), 14332(BLK), 14335(BLK), 14337(BLK)
Factory Exhaust System Removal:
1. Using a 3/8” drive ratchet and 15mm deep socket, loosen the two sleeve clamps at the cat-back connection
point. Both nuts must be loosened in order for the clamp to fully disengage. (Fig. A)
2. Using the 3/8” drive ratchet and 13mm socket, remove the bolt holding down the driver side hanger grommet
assembly. (Fig. B) Once the bolt is removed, push up slightly on the exhaust and slide the hanger grommet
assembly rearward to free it from the rear suspension sub-frame. Rotate the hanger grommet assembly a
minimum of 90° so that it will not interfere with the rear suspension sub-frame. (Fig. C) Place the bolt in a safe
location as it will be reused during the installation of the Corsa cat back exhaust system. Repeat this process for
the passenger side hanger grommet assembly.
3. Slide the stock exhaust assembly rearward until the stock resonator inlet pipes are free of the sleeve clamps.
Lower the front of the exhaust in order to create clearance between the resonator inlet pipes and the sleeve
clamps, then slide the complete exhaust forwards to remove the rear driver and passenger side hangers from
their respective hanger grommets. (Fig. D) The stock exhaust assembly will now be free from the vehicle.
(Fig. E)
NOTE: The use of a soap and water solution may aid in the removal of hanger grommets.
4. Remove both the driver and passenger side hanger grommet assemblies from the front muffler hangers using
grommet pullers or a similar device. (Fig. F) Set the hanger grommet assemblies aside, in a safe location, as
they will be re-used for the installation of the Corsa cat back exhaust system. This concludes the factory exhaust
system removal.
NOTE: The use of a soap and water solution may aid in the removal of hanger grommets.
