Note these have been replaced by our SS Dominator Headers #3140. Read more about the improvements here.

A design that has stood the test of time. Made in the USA, our headers are one-piece construction (not sleeved) with equal length tubes for maximum horsepower and torque. Designed so the starter can be removed with the headers in place and to clear the steering and clutch linkage. Made of 16 gauge 1 1/2″ diameter tubing for smooth flow into the 2 1/2″ final diameter collectors, they follow the same route as the stock exhaust system. Utilizes a 3/8″ thick flange for strength and to prevent gasket blow out. They fit 289, 302/5.0 and 351W/5.8 conversions. Compatible with C4 and AOD automatics and manual transmissions. Long tube headers are not recommended for use with C6 transmissions due to significant fitment interference. Will not work with GT-40P heads. If running an NV3550 or AX15, you will need custom intermediate pipes to clear the new transmission cross member (not available from Duff’s).
The Duffy’s Original with the driver side design was updated in 2001 to fit better with our #5350 Radius Arms. Come with hardware, premium gaskets and instructions.* These feature an inside and out metallic ceramic coating that resists temperatures up to 1600° F. They are incredibly rust, chip, and abrasion-resistant; lower underhood temperature; and have a “polished/aluminum” look that does not blue.

…Now available in Black Cerakote
Our satin black cerakote option has even higher heat resistance up to 2300° F as well as being more resilient than ceramic coating.

Important Note: These are not compatible with the Stage 8 header bolts.

  1. Trent Bonnett

    An amazing upgrade for Bronco. Great fit and amazing quality.

  2. Clifford Harrelson

    A great added look and upgrade that’s so beneficial. Easy install and built to last looks make these a “must have”. I added these along with a Duff’s dual exhaust system and just couldn’t be happier with the install and added performance. Highly recommend this.

  3. Brian Seager

    The headers look good and arrived in good condition. Installation wasnt to complicated. However the drop bracket on the equalizer bar hit the headers so i had to modify my clutch linkage. I am running a 351W and 3-speed manual transmission.

    I really appreciate the courtesy call about shipping. Everyone was great to work with. Your descriptions of the products are perfect. Thank you!
