Factory Exhaust System Removal:
1. Lower or remove the spare tire from the vehicle. Refer to the Owner’s Manual for how to do this on your
specific vehicle.
2. Loosen the spherical clamp at the front of the exhaust using 13mm socket and ratchet. (Fig. A)
Note: The use of a penetrating lubricant spray may make this step easier.
3. Support the rear of the tunnel muffler using a jack stand or similar device. Place a chain style cutter around the
tail pipe about 1-2” behind the muffler on the front half of the axle pipe. Cut the tail pipe at this location. (Fig. B)
Caution: The muffler is only supported by the jack stand and the hanger at this time. Take care as to not let it
fall and damage the vehicle or cause injury.
4. Remove the grommet from the head pipe hanger using grommet pullers or a similar device. (Fig. C) Remove this
section of the exhaust from the vehicle.
Note: Using a soapy solution on the grommet holes will make the job easier.
5. Using a small, flat head screw driver, gently pry up on the tab holding the clamp to the head pipe. Retain this
spherical clamp for use during Corsa exhaust installation. (Fig. D)
6. Using the ratchet, 15mm socket, and 12” extension as needed, remove the two 15mm bolts securing the spare
tire heat shield. Retain the bolts and heat shield for reinstallation later. (Fig. E)
7. Using grommet pullets or a similar device, remove the three hangers from the grommets supporting the tail
pipe. Remove the tail pipe from the vehicle by gently guiding it towards the rear of the vehicle, over the rear
axle.
Note: Using a soapy solution on the grommet holes will make the job easier.
8. This concludes the factory exhaust removal process.
