4. Loosen the band clamps at the rear of the H-pipe and slide them back.
5. Remove the nuts from the H-pipe at the manifold. Remove the H-pipe.
Note: If you are using the D925 X-pipe with the stock catalytic converters, it will be
necessary to cut the stock H-pipe assembly
approximately 4” in front of the hanger
bracket. It will prove to be more accurate by placing the X-pipe on top of the stock H-
pipe and mark the area to be cut (allowing enough for slip fit).
ASSEMBLY
1. Inst
all Doug’s Header Part No. D6682 per instructions.
2. Install the X-pipe hangers into the stock rubber mounts.
3. Slip the stock band clamps back over the end of the X-

5. Tighten all clamps evenly.

7. Connect the negative battery cable.
START 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.
IMPORTANT CHECK LIST
Be sure that all brake 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.
Double-check the tightness of all bolts including brackets and accessories.
