Stage 8 Collector Bolts:
#3081 [Add $29.95]

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. C6 transmissions will require modification. Will not work with GT-40P heads. If running an NV3550 or AX15, you will need custom intermediate pipes to clear the new transmission crossmember (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 Remflex gaskets and instructions.* These feature a inside and out metallic ceramic coating that resists temperatures up to 1600° F. They are incredibly rust, chip and abrasion resistant; lower under hood temperature; and have an "polished/aluminum" look that does not blue.

...Now available in Black Cerakote
Our satin black cerakote option has an 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.

*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.

5 of 5 Beautifully built September 27, 2019
Reviewer: Clifford Harrelson from Ocala, FL United States  
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 of 5 Good Product April 2, 2018
Reviewer: Brian Seager from Harker Heights, TX United States  
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.
