Factory Exhaust System Removal:
1. Use a small, flat head screwdriver to carefully pry off the spare tire mechanism cover plate in the rear bumper.
Insert the ignition key to remove the locking mechanism to gain access to the spare tire removal system. (Fig. A)
2. Using the spare tire removal kit from your vehicle, insert the square end into the spare tire removal shaft, then
turn the wrench counter-clockwise to lower the spare tire. (Fig. B)
3. Remove the two bolts securing the heat shield using a 15mm socket and ratchet. (Fig. C & D)
4. Place a chain style cutter around the tail pipe about 1-2” behind the most rearward hanger on the front half of
the axle pipe. Cut the tail pipe at this location. (Fig. E & F)
5. Remove the grommet from the tail pipe hanger (on the cut portion) using grommet pullers or a similar device.
(Fig. G)
Note: Using a soapy solution on the grommet holes will make the job easier.
6. Carefully remove the tail pipe section from the vehicle by lifting the tail pipe over the rear axle and backwards
under the rear bumper. (Fig. H)
7. Use a 13mm shallow socket and ratchet to loosen the spherical clamp on the head pipe. Remove the hanger
from the grommet in front of the muffler using grommet pullers or similar device. (Fig. J & K)
8. Remove the hangers from the grommets behind the muffler. Remove the head pipe at the spherical connection
to free the muffler section from the vehicle. (Fig. L, M, & N)
9. Use the small, flat head screwdriver to gently pry up the tab on the head pipe and remove the factory spherical
clamp. Set aside the clamp to be reused during the installation process. (Fig. P)
