Disclaimer: By installing any PPE products, you indicate that you
have read the following and agree to these terms:
The purchaser is responsible for following the instructions and
safety guidelines set by PPE.
PPE assumes no responsibility for any damages from
improper installation, abuse, lack of care or incompatibility with
other manufacturers products.
The purchaser is responsible for any damage to the products
if returned.
These products are manufactured using 304 polished
stainless steel. Exhaust heat will turn the nish to a bluish/gold
color. This is normal and not a cause for a warranty claim or return.
Warranty: PPE will repair or replace the product at no charge
(See enclosed warranty card). We are not responsible any labor
charges or shipping fees.
Installation: These next few steps will be required for installing all
the above part numbers.
Raise and support the vehicle on jack stands or a lift.
Remember to block or chock the rear tires.
Disconnect the negative (-) cable from the battery.
Label and remove the spark plug wires. Be careful as the
rubber boot may have seized to the spark plug itself. Gently twist
the boot until it breaks free.
Make sure to remove any debris which may have gathered
near the exhaust ports.
Soak all necessary bolts with penetrating oil to allow for easy
removal. Be careful, old and rusty manifold bolts break easily.
Removing them from the head is no walk in the park.
Unbolt the motor mounts as jacking or lifting of the engine may
be necessary.
Removal of the front rim/tire may help gain access to lower
header bolts.
Dip stick tube removal may be necessary on some
applications
Unbolt the factory h-pipe from the factory manifold and the
factory cat-back. Disconnect the O2 sensor wiring and remove the
h-pipe.
Unbolt and remove the driver and passenger side factory
manifolds. Removal of AIR or EGR accessories may be necessary
on some applications.
Clean and prep the gasket mounting surface for the new
headers.
When installing your new headers, snug the bolts starting from
the center working your way to each end in a crisscross pattern.
Finish by tightening all the bolts using the same method. It’s always
good to use anti-seize compound when installing header bolts.
