Factory Exhaust System Removal:
1. Beginning at the rear of the vehicle on the driver’s side, use the 15mm socket and ratchet to loosen and remove
the hardware securing the muffler. (Fig. A) By pulling up and rearward, separate the rear muffler from the axle
pipe. (Fig. B)
2. At this point, remove the rear muffler from the factory rubber grommet. This rubber grommet is above the
muffler towards the outside of the car vehicle, making access with grommet pullers difficult. It is possible to
remove the muffler from the grommet by hand if grommet pullers will not fit into the cavity. (Fig. C) After
removal, set the muffler aside.
Note: A soap and water solution will aid in removing hangers from rubber grommets.
3. Remove the driver’s side axle pipe hanger from the factory grommet (Fig. D) Repeat on the passenger’s side of
the vehicle.
4. At the front of the vehicle, use the 13mm socket and ratchet to remove the two bolts securing the front driver’s
side hanger bracket to the chassis. Save the bolts for later use when installing the Corsa exhaust system. (Fig. E)
Repeat on the passenger’s side of the vehicle.
5. Using the 14mm socket and ratchet, remove the spring nuts from the factory studs on both the driver’s and
passenger’s side of the vehicle. (Fig. F)
6. Carefully remove the factory exhaust system from the vehicle by first pushing the system towards the rear of the
vehicle. Once the studs are free of the flanges at the front, slightly lower the front. At this point, remove the
passenger’s side rear hanger from the grommet above the muffler.
Note: There may be a ground strap between the vehicle frame and the muffler hanger. This strap clips in place
and can be easily removed from the muffler.
7. Set the factory exhaust system to the side. Remove the rubber grommets from the sides of the factory tunnel
muffler using the grommet pullers. Save the rubber grommets for later use when installing the Corsa exhaust
system. (Fig. G & H)
Note: A second person helping is necessary during this step due to the size and weight of the factory exhaust.
8. Using the 15mm socket and ratchet, loosen the clamp on the passenger’s side of the vehicle near the flange
connection. Remove this short connector piece from the vehicle, leaving only a flange on the driver’s side.
Note: A penetrating lubricant spray used at this expansion joint may make separating these pipes easier. The
use of a rubber mallet or hammer to gently tap the flange rearward may also aid in removal.
This concludes the factory exhaust system removal process.
