NOTE: This system was designed to connect to CORSA X-Pipe PN: 14761 and CORSA Cat-Back PNs: 14762, 14763, 14764,
14765, 14766, 14767, 14768, and 14769. 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 heat shield on the steering shaft. Wrap the flexible heat shield around the steering shaft and secure
with a couple metal zip ties. WARNING: Near the top of the steering shaft is an internal plastic component that
can be damaged by heat from the headers if the heat wrap is not installed. Slide the heat shield up as far as it will
go, near the firewall.
3. Install the front O2 sensors into the header collectors. WARNING: They are sensitive electronic components and
can be easily damaged. Ensure the proper side sensor is installed in the correct header.
4. Study the exhaust manifold gaskets included with the hardware kit. Place the gaskets on the header and align the
bolt holes. The gaskets’ front and backs ARE NOT symmetrical. It is possible to improperly install them on the
vehicle with four of the five holes lined up, which will prevent the last bolt from going in. Ensure you have the
proper orientation before bolting the headers to the engine.
5. Prepare 5 of the header bolts with a small amount of
anti-seize to prevent galling of the aluminum head. Lift
the driver side header up and align it with the gasket
and the head of the engine. (This step is much easier
with the help of another person).
6. Start the header bolts by hand to ensure they are
not cross-threaded. Use a 12mm wrench or socket
and ratchet to install them. DO NOT fully tighten
the bolts at this time. Reinstall the steering shaft
and bolt in place.
7. Repeat Install Step 5 on the passenger side, only snugging the bolts. Reinstall the heat shield over the starter and
secure with the 10mm bolts from Removal Step 16.
