Stainless Steel Headers for Ford F150 F250 BRONCO (1987-1996) 5.8L 351 Engine

Stop the dreaded "manifold tick" on your OBS Ford and uncork the torque potential of your 351 Windsor with these high-flow stainless steel headers.

Performance Stainless Steel Header System for 1987-1996 Ford F-Series & Bronco (5.8L Windsor V8)

If you are driving a "Bricknose" or OBS (Old Body Style) Ford F-Series or Bronco with the 5.8L V8, you are likely familiar with the limitations of the factory exhaust. The stock cast iron manifolds are notorious for two things: cracking (causing that annoying ticking sound on cold starts) and restricting airflow. The 351 Windsor is a legendary workhorse known for its towing capability and low-end grunt, but the factory "log" style manifolds strangle its ability to exhale, trapping heat and backpressure against the cylinder head.

This racing-spec header system solves these issues by replacing the restrictive cast iron with T304 stainless steel. Designed with oval ports (1.50" x 1.25") to perfectly match the 5.8L OHV cylinder heads, these headers smooth out the exhaust pulses, allowing the engine to scavenge spent gases more efficiently. This reduction in backpressure allows the engine to pull in a fresh air/fuel charge faster, resulting in an immediate gain of 10-15 horsepower and torque. Whether you are hauling heavy loads or just want your truck to run cooler and smoother, this is the mechanical efficiency upgrade the Windsor platform demands.

Built for durability, the T304 stainless construction resists the rust and corrosion that plague the original components. The 2.75" collector ensures that high-volume exhaust flow exits quickly, giving your truck a deeper, more aggressive tone compared to the muffled factory sound. It’s a functional restoration upgrade that eliminates leak-prone iron and adds modern performance to your classic Ford truck.

Why You Need This Upgrade

• Eliminate Manifold Cracks: Replaces brittle, crack-prone factory cast iron manifolds that cause exhaust leaks and ticking noises.
• Torque & Horsepower Gains: Dyno-proven improvements of 10-15 HP/TQ by reducing exhaust backpressure and improving scavenging.
• Port-Matched Design: Features 1.50" x 1.25" oval inlets specifically designed to match the 5.8L OHV exhaust ports for smooth flow.
• Heavy-Duty Material: Constructed from T304 Stainless Steel to withstand high exhaust temperatures and road grime without rusting out.
• High-Flow Collectors: 2.75" outlets maximize flow volume, improving throttle response and creating a classic American V8 rumble.

Installation Notes

Professional installation is highly recommended. These trucks are now over 30 years old, and factory manifold bolts are often rusted or seized in the cylinder heads. Mechanic's Tip: Soak all manifold bolts with high-quality penetrating oil for at least 24 hours before attempting removal to reduce the risk of snapping bolts in the head. The kit includes gaskets and hardware necessary for the header installation.
