INSTALLATION
3.
Some Doug’s Tight Tuck Headers are the same for left and right sides; others are specific to
each side. Determine which type you have.
4. Carefully check the fit of each header for clearance. Pay special attention to motor mounts
and any lines or hoses that might come in contact with the headers. It is not uncommon to
have to trim motor mounts or move lines and hoses to clear the headers. Additionally
steering shafts and linkages should be clear of any interference and suitably modified if
necessary. In some cases a Mini Starter might be necessary as well.
5. When you are satisfied with the fit of your header, slip into place using the supplied gasket
and special header bolts. Use anti seize on headers bolts if installing o Aluminum Heads.
6. Tighten the header bolts evenly starting in the center and working your way out.
7. Install the reducers using the supplied gaskets and hardware.
8. Weld the reducers to the exhaust system and install them onto the headers utilizing the
gaskets and bolts supplied. Your exhaust can be fabricated now from the reducers back. Go
to
for a complete line of mufflers, tips and tubing to complete your
exhaust.
9. Install spark plugs and connect the wires to the proper plug.
10. Connect the battery cables.
IMPORTANT CHECK LIST
Be sure that all brake lines, transmission lines, and fuel lines are clear of headers
and/or connector pipes.
All spark plug wires, battery cables, or other electrical components should be
clear of headers and/or connector pipes.
If dipstick tube was removed, make sure it is installed properly and that the dipstick
has been replaced.
Double-check the tightness of all bolts including brackets and accessories
.
STARTING THE ENGINE
Start the engine and allow it to warm up to operating temperature. Check for any unusual
noises or exhaust leaks. If every thing is OK, stop the engine and tighten all bolts while
the engine is still warm.
NOTE: Check the bolts periodically to make sure they have not loosened. Re-tighten
after the first 500 miles and then again at 1000 miles.
