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.
DISASSEMBLY
