PerTronix

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. 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 and X-Pipes, 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 X-Pipe.

BEFORE STARTING

We recommend welding all pipe slip joints. If no welding equipment is available at the

time of installation, use the furnished clamps to secure the pipes until they can be

welded. If you are not going to weld the slip joints, apply a liberal amount of Ultra

Copper Hi-Temp Sensor-Safe Silicone Sealer to the joints to further ensure a proper

seal.

This X-Pipe is designed to fit with Doug’s Header Part No. D6679 only!

This X-Pipe will attach to a stock Ford exhaust or catalytic converter.

DISASSEMBLY

1. Disconnect the negative battery cable from the battery.

2. 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.

3. Remove O

sensors and hang up out of the way until the X-Pipe is installed.

4. Remove existing manifolds and related exhaust system.
