Exhaust Manifold Headers Shorty for Ford Mustang GT & Cobra (1996–2004) 4.6L

High-Flow T304 Stainless Shorty Headers for Ford Mustang 4.6L

Replaces the restrictive factory cast-iron exhaust manifolds with mandrel-bent shorty headers to improve exhaust scavenging and lower engine bay temperatures.

The Stock Mustang Restrictive Airflow

The factory Ford Mustang 4.6L cast-iron exhaust manifolds are notoriously restrictive, plagued by rough internal casting flashes and sharp log-style bends. These manufacturing compromises create excessive exhaust backpressure and uneven cylinder scavenging. Under heavy load, the dense cast iron retains extreme heat, causing localized heat soak that degrades surrounding under-hood components and restricts the Modular V8's top-end horsepower potential.

The Engineering Solution

These shorty headers eliminate OEM flow restrictions using mandrel-bent T304 stainless steel tubing, ensuring rapid and smooth exhaust gas evacuation from the cylinder heads. The precision TIG-welded construction offers superior thermal resistance and prevents the structural cracking commonly seen in cheaper mild-steel alternatives. By optimizing the primary tube routing, these headers improve exhaust pulse scavenging, which directly translates to noticeable gains in torque, sharpened throttle response, and a deeper exhaust resonance. Designed as a direct bolt-on upgrade, they mate seamlessly to the factory exhaust system without requiring chassis modifications, utilizing the included metal gaskets for a reliable, leak-free seal.

Technical Specifications

Compatibility

• 1996–2004 Ford Mustang GT 4.6L 2V SOHC V8
• Note: Made for 4.6L 2V SOHC cylinder heads.
• FITMENT PRE-WARNING: 
  We highly recommend professional installation and ask the shop if they have experience in aftermarket exhaust systems, catbacks, manifold headers installations, they should advise you, like we are, that you may have a side or a small area of this system rubbing up on an engine part and not able to clear it, in which case experience and troubleshooting is necessary. It is rare, most customers don't experience this issue, these sell regularlry, but it could occur, you may reach out to us for assistance.

The Ford Muscle Standard

For modern American muscle, optimizing exhaust flow is non-negotiable for maximizing the Modular V8's powerband and achieving that signature aggressive exhaust note.

Common Questions

Which Ford Mustang models do these shorty headers fit?
These shorty headers are built for the 1996–2004 Ford Mustang equipped with the 4.6L Modular V8 across the SN95 and New Edge chassis generations.

What cylinder head configuration is required on the 4.6L V8?
The 1996–2004 Mustang GT uses 4.6L 2V SOHC cylinder heads, while the Cobra uses 4.6L 4V DOHC cylinder heads with distinct exhaust port shapes; check your cylinder head type before installation.

What material are these headers made from?
They are constructed from mandrel-bent T304 stainless steel tubing with precision TIG-welded joints for thermal resistance and durability.

What is included with the headers?
The kit includes the T304 stainless steel shorty headers along with metal exhaust gaskets for a reliable seal.

Do these headers bolt up to the factory exhaust system?
Yes, they are designed as a direct bolt-on replacement for the factory cast-iron exhaust manifolds and mate to the stock exhaust system without chassis modifications.
