Factory Exhaust System Removal:
1. Locate and loosen the furthest front bolt holding 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 brace and sliding
it rear wards. Repeat this process for the passenger side convertible brace. (Fig B) 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. Starting on the driver side, measure 19 ¾” away from the flange on the stock resonator, following the outside
profile of the exhaust pipe. The tape measure should follow the bend profile of the pipe. (Fig. C & D) Next,
measure 20” away from the flange on the stock resonator, following the outside profile of the exhaust pipe of
the passenger side. (Fig E) Using a chain cutter or similar device, cut both the driver and passenger side exhaust
pipes at the marked locations. (Fig F) Place a jack stand or similar device under the stock tunnel section of the
exhaust for support. Once the axle pipes are cut, there are no additional stock hangers supporting the tunnel
section.
3. Using a 3/8” drive ratchet and 13mm socket, remove the bolt holding down the driver side hanger grommet
assembly. (Fig G) 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 H) Place the bolt in a safe
location as it will be reused during the installation of the Corsa axle back exhaust system.
4. Lower the cut end of the driver side muffler assembly just enough to create clearance between the pipe and any
suspension components. Slide the whole muffler assembly forward to remove the rear muffler hanger from the
hanger grommet. (Fig I) The driver muffler assembly will now be free from the vehicle.
NOTE: The use of a soap and water solution may aid in the removal of the hanger grommets.
5. The passenger side muffler assembly is removed mimicking above steps #3 and #4 for the passenger side. (Fig J)
6. Remove both the driver and passenger side hanger grommet assemblies from the rear mufflers using grommet
pullers or a similar device. (Fig K & L) Set the hanger grommet assemblies aside, in a safe location, as they will
be re-used for the installation of the Corsa axle back exhaust system.
7. IMPORTANT: Carefully and thoroughly de-burr the stock tunnel muffler (resonator) outlet pipes from any burrs
and sharp edges. This is important as any burrs will prevent the stock to axle-back adapters from sliding over
the stock exhaust pipes. This concludes the factory exhaust system removal.
