2015 Ford Mustang GT 5.0L V8 Convertible
PN 14341(BLK) & 14342(BLK)
Factory Exhaust System Removal:
1. Locate and loosen the furthest front bolt securing the driver side factory convertible brace using a 3/8” drive
ratchet and 13mm deep socket. (Fig. A) Loosen the bolt so that there is about a ¼” – ½” gap between the bolt
head and the brace. Do not remove the bolt completely. Remove the factory driver side convertible brace by
removing the 8 following bolts working your way from front to rear; then slightly lowering the bracing and
sliding it rearwards. Repeat this process for the passenger side convertible brace. Place both the driver and
passenger side braces in a safe location during the remaining stock exhaust removal procedure and installation
process of your Corsa Performance exhaust system.
2. 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. B)
3. Using the 3/8” drive ratchet and 13mm socket, remove the bolt holding down the driver side hanger grommet
assembly. 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.
4. 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.
5. 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.
