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. D6682 only!
