Exhaust System Installation
Cat Back Exhaust System
2016 Shelby GT350
PN 14348
Factory Exhaust System Removal:
1. Using a clip removal tool or a flat head screw driver remove the six plastic clips holding the rear diffuser to the
bottom of the rear bumper. (Fig. A) Using a 13mm socket and 3/8” drive ratchet, remove the two bolts located
on the bottom of the diffuser. Remove the second pair of bolts at the axle pipe hanger grommets. (Fig. B)
Lastly, remove the two Christmas tree connectors at the rear of the diffuser and remove the diffuser from the
vehicle. Place the diffuser and hardware in a safe location as it will be reused during the installation of the Corsa
Performance cat-back exhaust system.
2. Unplug both the driver and passenger side rear exhaust valve actuators by sliding the red plastic clip on the plug
away from the actuator. Once the clip is slid back, push down on the plug tab and pull the plug off the actuator.
(Fig. C)
3. 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. D)
4. Using the 3/8” drive ratchet and 13mm socket, remove the bolt holding down the driver side hanger grommet
assembly. (Fig. E) 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. 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.
5. 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 forward to remove the rear muffler driver and passenger side hangers
from their respective hanger grommets. The stock exhaust assembly will now be free from the vehicle.
NOTE: The use of a soap and water solution may aid in the removal of hanger grommets.
6. Remove both the driver and passenger side hanger grommet assemblies from the axle pipe hangers using
grommet pullers or a similar device. 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. (Fig. F)
7. Using an 8mm socket and ¼” drive ratchet, remove the three nuts holding down the driver and passenger side
valve actuators. Lift the actuators over the studs and place them in a safe location as they will be reused during
the Corsa Performance cat-back exhaust installation process. This concludes the factory exhaust system
removal.
NOTE: The use of a soap and water solution may aid in the removal of hanger grommets.
