Pypes Performance Exhaust HDR76SK - Manual

Thanks again for purchasing your new stainless steel Pypes Performance Ex-
haust Long tube headers. Please be sure to confirm all the components in the
kit were received in your shipment before beginning installation. If you find any
components missing, please contact our office at 800-421-3890 for replace-
ment. Technical assistance is available both on line at www.pypesexhaust.com
or by calling 800-421-3890
Pypes exhaust are designed for the savvy home installer but highly recommends hiring a professional, one that is familiar with the
installation of high performance exhaust products. Headers are designed to increase the performance of your vehicle, and as such
are designed differently than your stock exhaust system. Extra care must be taken to ensure that hoses, cables, electrical lines,
fuel lines, hydraulic lines, or any other objects are not in contact with, or located too close to your installed system.
Work Safe: When supporting a vehicle on jack stands, be sure the ground surface
is level and solid, hot asphalt will not support jack stands. Double check your place-
ment before sliding under the vehicle.
Note: Many factors may affect the installation: broken, worn or aftermarket motor
mounts, aftermarket suspension components, bent frame or chassis components
from accidents, different engines or cylinder heads.
Attention: These items have a highly polished finished which can be marred or
scratched during installation. If these products need to be returned and are dam-
aged in any way, you will be charged a 20% restock/polish fee.

Requires Tools:
7/8” open end wrench or O2 sensor socket
Assorted metric sockets and wrenches
Ratchet and extensions
Miscellaneous hand tools
Floor jack and jack stand or hydraulic lift
Anti-seize
While this installation can be done on the floor with the use of jack stands we
strongly recommend that this job be completed utilizing a hydraulic lift. You will
need 24 to 30 inches of ground clearance to slip the header into position from
the bottom of the vehicle. Please allow the engine to cool for a minimum of 90
minutes before starting the removal and installation steps. The use of safety
goggles will protect you from falling debris that may be dislodged from the bot-
tom of the vehicle during the removal and installation process.
Stock system removal:
Begin by locking the steering column in place so it cannot rotate once the
steering shaft is disconnected in a later step. Failure to do so may result in
damage to the steering wheel controls if your vehicle is so equipped.
Remove the battery terminals by starting with the negative cable first fol-
lowed by the positive. We have found no need to remove the battery and tray
but if you choose to it will give you more room to remove and install the top
side manifold bolts.
Remove the strut tower brace bar if your car is so equipped along with the
engine cover.
Loosen the clamp that holds the air inlet tube to the mass air sensor and
remove the tube from the mass air. Again we found no need to remove the
factory air box but if you feel the need it will gain you better access to the
manifold bolts.
Remove the driver and passenger side O2 connector where it’s secured on
the back of the block at the bell housing stud to allow the sensor to be relo-
cated further back.
Remove the outside nuts holding the cats to the manifolds on both sides as
well as the nuts on top of the engine mounts.
At this time you can raise the car with either jack stands of a hydraulic lift.
Again we strongly recommend the use of a lift for the following steps.
Loosen and remove the 2 rear O2 sensors in the H-pipe and mark their
locations so they can be reinstalled in the same positions in your new x-pipe.
