Removal Instructions
FACTORY MANIFOLD
14. Remove the bolts securing the under tray to the bottom of the vehicle. Two are 18mm bolts near the front and
the rest are 13mm. Save bolts for reinstallation (Install Step 16). NOTE: Two bolts near the middle of the tray are
in slotted holes and only need to be loosened, not removed. WARNING: Loosening them a few turns allows
removal of the tray and should prevent it from falling and causing injury.
15. Locate the two thin cross braces, connecting the
subframe to the frame of the vehicle. Loosen the
bolts toward the outside using an 18mm socket and
ratchet. Loosen and remove the two 18mm bolts on
the subframe and then remove the braces. Save bolts
and braces for reinstallation (Install Step 15).
16. Use a 10mm wrench or socket and ratchet to remove
the three bolts securing the heat shield for the
starter. Save for reinstallation (Install Step 7).
17. Unbolt and separate the steering shaft from the rack.
WARNING: DO NOT rotate the shaft while it is
disconnected. It may cause issues with turn signals,
horn, and alignment.
18. Remove the X-Pipe from the vehicle by removing the
nuts (save for Install Step 12) at the front of the X-
Pipe using a 15mm socket and ratchet. Take care as
the manifolds are loose and not connected to the
engine.
19. Support the front of the X-Pipe with a jackstand,
screw jack, or similar device. Loosen the clamps at
the rear of the X-Pipe with a 15mm socket and
ratchet.
20. Remove the two bolts (save for Install Step 12)
securing the X-Pipe to the transmission bellhousing
using a 13mm socket, extension, and ratchet.
Carefully remove the X-Pipe by pushing the mufflers
toward the rear and lowering the X-Pipe from the
vehicle. WARNING: Ensure the factory manifolds and
catalytic converters do not hang on the O2 sensor
wires.
