2011-2014 FORD MUSTANG GT 5.0L V8
Long Tube Headers: 1.875” Primary, 3.0” Collector
Part #: 16016, 16116
NOTE: This system was designed to connect to CORSA X-Pipe PN: 14370 or 14421 (NOT 14318), CORSA Connection Pipes PN:
16018, and CORSA Axle-Back Part #: 14317 and 14316. Tip color does not affect fitment. The need for additional modification and
fabrication may arise. The vehicle owner assumes all responsibility for subsequent fitment issues.
CAUTION: Never work on a hot exhaust system. Allow the vehicle to cool for at least an hour and a half. Always wear eye protection
when working under a vehicle. It is recommended to use cotton gloves in order to protect the stainless steel surface of the header from
permanent grease and oil stains.
NOTE: Lift the vehicle using a hydraulic lift or jack and jack stands. A lift is strongly recommended because three (3) feet or more is
needed to install the driver side header from the underside.
INSTALLATION INSTRUCTIONS
CORSA EXHAUST
1. Remove all exhaust system components from
the shipping boxes, including clamps and
hardware.
2. Install the passenger front O2 sensor extension
wire. PRO TIP: Route it around the bellhousing
at the rear of the engine. This keeps it tucked
away from the header once installed.
3. Locate one of the studs from Removal Step 23
along with both bags of bolts provided in the
hardware kit. Compare the SHORT end threads
on the stud to both sets of bolts. Pay close
attention to how well they match: One set of
bolts is for newer vehicles with coarse threads.
The bolts with a fine thread are typically for older
vehicles. WARNING: Ensure the threads on the
stud match the bolts otherwise serious damage
can be done to the engine head.
NOTE: Check that the bolts in engine are finger
tightened only.
4. Prepare the ends of the correct matching bolts
with a small amount of anti-seize lubricant.
Locate the multi-layer steel header gaskets in the
hardware kit.
Notice how the triangular shaped holes at the
ends align with the top row of holes on the
engine head at the front and rear. Insert two
prepared bolts through the triangular corners of
the gasket and begin threading them into the
front and rear holes. WARNING: Only thread the
bolts into the holes enough to ensure they are
not cross-threaded.
Thread in two more bolts for a total of 4 along
the top of the gasket.
