Early Bronco Exhaust Headers & Gaskets

Serious Flow for Serious Builds: WILD HORSES Early Bronco Headers

When it comes to building a Bronco that breathes right and pulls hard, headers aren't just a nice-to-have - they're essential. At WILD HORSES 4x4, we’ve spent years refining our headers to fit the unique needs of Early Bronco owners. Whether you're swapping in a modern 5.0L EFI motor or keeping your classic 289, 302, or 351W V8, our Bronco-specific headers are built to deliver serious low-end torque, horsepower gains, and trail-ready reliability.

We don’t just sell headers - we design them with real-world fitment and performance in mind. Let’s break down why WILD HORSES headers are the go-to choice for 1966–77 Ford Bronco builds.

5.0 Shorty Headers – EFI Swaps Made Easy

Swapping a late-model fuel-injected 5.0L into your Early Bronco? Our 5.0 Shorty Headers were specifically designed to make that job easier. These compact, tight-fitting headers offer all the performance of full-length tubes but with the added benefit of no starter interference and simple installation - no massaging or modifying your engine bay required.

Despite the compact design, these headers still pack a punch where it matters: low-end torque and mid-range horsepower. They’re also a solid choice for factory 289 and 302 motors, making them one of the most versatile header options in our lineup.

Available Finishes:

• Bare stainless steel

• Ceramic-coated for improved heat control and corrosion resistance

Standard Features:

• Heavy-wall 14-gauge steel tubing

• 3/8” laser-cut flanges to eliminate warping

• Thick steel collector dome

• Includes gaskets, hardware, starter tubes, and optional O₂ sensor fittings

• Backed by our lifetime warranty

Pro Flow Headers – Long Tubes for Maximum Performance

For those looking to squeeze every ounce of performance out of a small or big small-block V8, the Pro Flow Long Tube Headers are the answer. These were built with maximum scavenging and flow in mind - ideal for 289, 302, and 351W engines in 1966–77 Broncos.

The one-piece, long-tube design uses 1.5” diameter 16-gauge steel tubing and features modern “dome-style” collectors that eliminate the need for collector gaskets entirely. That means less maintenance, fewer leaks, and better overall durability. And thanks to smart routing, you won’t have to remove the headers to service the starter - a rare bonus in the world of long-tube designs.

Highlights Include:

• 3/8” flanges to prevent warping under heat

• One model fits all three V8s: 289, 302, and 351W

• One-piece construction for long-term durability

• Complete with installation hardware and gaskets

• Built to flow, tuned for torque

A Fit That Works – No Guesswork Required

Every header we offer is designed specifically for the Early Bronco platform, not adapted from another vehicle. That means better fitment, less wrenching, and a cleaner install overall. No hitting the frame rails, no starter conflicts, and no grinding required - unless you’re running one of the rare emissions-era 302s with 3- or 4-port air injection tubes (common in 1974–75). Even in those cases, a little flange clearance work is all it takes to make them fit.

Note: None of our headers are compatible with 5.0 "P" heads. Also, they’re not designed to defeat any emissions components, so your existing smog system can remain intact and legal.

At WILD HORSES, we’ve built our reputation on quality parts, real-world experience, and a no-nonsense approach to product development. These headers are the result of years of testing - on the trail, in the garage, and under the hood of our own rigs. We’ve dealt with the headaches of poor fitment and warped flanges, and we built these headers so you don’t have to.

When you bolt up a set of WILD HORSES headers, you’re getting:

• Proven performance gains

• Quality materials and construction

• A clean, frustration-free install

• Lifetime warranty support

• Components tested by people who actually drive Early Broncos

Final Thoughts: Breathe New Life into Your Bronco

Your engine can’t make power if it can’t breathe - and factory exhaust manifolds just don’t cut it. Whether you’re going for a reliable street truck, a trail-tuned crawler, or a weekend cruiser, WILD HORSES Early Bronco Headers will wake up your V8 and transform your driving experience.

The right headers make all the difference - and these were built by Bronco people, for Bronco people.

HEADER TECH

• None of our headers will fit the 302 engines with 3 or 4 port air injector tubes. These were sometimes used on 74-75 Broncos as part of the emissions system. All of the headers can be modified to fit by grinding clearance on header flange.
• None of our headers are designed to fit 5.0 "P" heads.
• Headers do not require any modification of the smog system to render it inoperable. Existing smog systems should always stay intact. Consult your local laws before ordering.
