Doug’s Headers is a division of Pertronix Performance Products and they now offer FE Headers for 1967-’70 Mustangs. Originally designed for the 1968 factory Cobra Jet Super Stock racers the original Doug’s Headers part number D627 is tuned long tube header specifically designed to fit 390-428 FE engines in the very confining engine compartment environments of the 1967-70 Mustangs.

The D627 features two tubes that cross under the oil pan for improved fitment and better power. Re-released by Doug’s Headers, the D627 further strengthens the Doug’s brand as the leader in muscle car headers with a rich history dating back to 1958. These headers are built with 3/8” thick flanges at the cylinder head and three-bolt outlet flanges. The four-tube under chassis exit design is made from 16 gauge tubing for durability with large 2” primaries and 3 1/2” collectors for increased horsepower and torque across the power band.  The design accommodates both automatic and manual transmission cars with or without power brakes. The headers come standard with a polished high luster heat and corrosion resistant metallic ceramic coating for a rich appearance and long life.  They come complete with reducers, 1100º F rated gaskets and premium installation hardware.  We found a set for $830.00. These headers can also be ordered uncoated.
