holding the tailpipe hanger assembly located to the inside of the driver and passenger side exhaust tips. (Fig. D)
The tailpipes will no longer be supported. Slightly lower the passenger side tailpipe assembly and remove
rearwards. Next, slide the driver side tailpipe assembly rearwards to free it from the connection point and
maneuver the tailpipe from over the axle and around the spare tire. (Fig. E) Leave the hanger grommet
assemblies on the tailpipe hangers as the tailpipe assemblies will be reused in the installation portion of these
instructions.
4. Loosen the clamp and sleeve clamp connection located after the stock resonator using a 15mm deep socket and
ratchet. The stock clamp is welded to the resonator assembly and cannot be removed or rotated. (Fig. F)

(Fig. G) Next, loosen and remove the bolt holding up the rear muffler hanger assembly. (Fig. H) The rear
muffler will no longer be supported; remove by sliding it rearwards to free the muffler inlet pipes from the
connection point. (Fig. I)
6. Remove the stock sleeve clamp from the muffler inlet pipe by prying open the spring clip with a flat head screw
driver and sliding the clamp off the pipe. (Fig. J) Place the stock sleeve clamp in a safe location as it will be
reused during the installation of your new Corsa Performance Exhaust System.
7. Removal all of the hanger grommet assemblies from the stock rear muffler and store them in a safe location, as
they will be reused during the installation of your Corsa Performance Exhaust System. (Fig. K & L)
