thanks you for choosing
DOUG’S HEADERS
, the best fitting, highest quality header on
the market. In order to realize the full potential of our good fit, please read and understand these
instructions completely prior to starting work.
Check to make sure you received the proper parts for your application. The header number will be
stamped on the engine flange. If you are unsure you have received the proper parts call before you start
work.
Be sure to work safe! Whenever you work under the vehicle be sure that it is located on level, solid
ground and is supported by adequate safety stands! Remember: Hot asphalt will not support most
jack stands!
Many factors affect the installation of headers, some of which are broken or aftermarket motor mounts,
accidents that impact the configuration of the frame, and/or the installation of different engines or
aftermarket cylinder heads. Most installations require some welding. If you are uncomfortable with
welding operations, we recommend that you contact a professional exhaust system specialist to install
your new headers.
Attention Customers breaking in new engines: Due to the extreme heat generated during the break-in
process, the appearance of the ceramic coating may be altered in certain areas. The protection
characteristics and thermal barrier properties of the coating is never compromised. It is recommended
that a cast iron manifold or old set of headers be used for this process.
Notice: The coating of these headers can be marred or scratched during installation. If the header needs
to be returned and is damaged, you will be charged for recoat.
