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.
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
1) Disconnect the negative battery cable from the battery.
2) If the car does not currently have an exhaust system installed, skip down to the Installation
section.
3) If a car lift is not available, raise the vehicle 2 feet or higher and support it with adequate
safety stands. Make sure the vehicle is on a flat solid surface and is stable. This step is for
removing existing exhaust pipes.
4) Apply penetrating oil to all nuts and bolts to be removed.
5) Remove and mark all spark plug wires and then remove all spark plugs.
6) Disconnect the head pipes from the exhaust manifolds and remove the manifolds.
Depending on the application, you may be required to remove the alternator, dipstick, clutch
linkage, and/or oil filter. In some cases it may be necessary to remove the starter and power
steering unit. Only remove what is necessary to allow the removal of the manifolds or the
installation of the headers.
7) Remove the gaskets and any gasket material or any carbon deposits that remain on the
head surface. The use of a gasket removal agent or scraper will ease the removal of any
gasket material. Use care not to get debris into ports or spark plug holes.

Doug’s Tight Tuck Headers are a Universal Design and as such we certainly cannot cover all
contingencies that the installer may encounter. Variations in Steering, Motor Mounts, Frames and
accessories are just some of the variables that can cause interference.
