DOUG’S HEADERS
, the best fitting, highest quality header on
the market. In order to realize the full potential of our good fit you need to read and understand these
instructions completely. Please read through the complete instructions prior to starting work.
CHECK TO MAKE SURE YOU RECEIVED THE PROPER PARTS FOR YOUR APPLICATION.
THE HEADER NUMBER WILL BE STAMPED ON THE HEAD FLANGE. IF YOU ARE
UNSURE YOU HAVE RECEIVED THE PROPER PARTS CALL BEFORE YOU START WORK.

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. 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 headers.
