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, 1.5” diameter tubing for smooth flow into the 2.5” 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. C6 transmissions will require modification. Will not work with GT-40P heads. If running an NV3550 or AX15 transmission, using our headers will require a custom intermediate pipe to work with the new transmission crossmember (not available from Duff's).
The Duffy's Original Headers with the driver side design updated in 2001 to fit better with our #5350 Radius Arms. Come with hardware, premium gaskets and instructions.*

+As of May 2018, these headers come painted with a Hi-Temp Header Paint. They start as black but after heating a few times settle in as more of a dark gray matte finish. (They can be lightly scuffed and top coated with other high temp finishes.)

*The regulation of emissions production, noise levels, and safety standards is undertaken by the federal government, each of the fifty state legislatures and by many local municipalities, towns and counties. California Vehicle Code Sections 27156 and 38391 prohibit the advertising, offering for sale, or installation of any device which modifies a vehicle’s emission control system unless exempted. James Duff headers have not received an exemption from these code sections and are not legal for sale or use in California on vehicles originally equipped with catalytic converters. It is illegal, except for vehicles only driven off-road, to remove or otherwise render inoperative any emission control device on regulated motor vehicles. In the other 49 states, it- is the responsibility of the ultimate consumer to check federal and local laws to determine if JDI products are legal for use on their vehicle.

Best fitting header out there! March 3, 2019
Reviewer: Johnny C. from Phoenix  
I've had these on my rig for close to 20 years. Well, they're the second set. I got a revised version in 2002 when I upgraded to long arms and needed one to clear on the driver side. Had no problem finding a home for the old ones. First ones were black, upgraded to ceramic for the second set. Both work equally well but the ceramic is still looking good.

Shipping March 12, 2018
Reviewer: Jeff Gould from Johnstown, CO United States  
Terrible job packing the headers. Showed up all scuffed up. I will be ordering from wild horses from now on.  
JDI: We're sorry you feel this way. As stated in the description, the black paint on our headers is simply for rust prevention during storage. It is not a final finish. Any paint other than a high temp or ceramic coating WILL burn off the first time the engine is brought to temperature. We are one of the only Bronco houses still selling a bare/black USA header for the more budget minded build. Our ceramic coated headers are packed to prevent scratching in shipment as the coating dictates. If you read many of our other reviews, you will see that we are known for HD packaging.
