Video Description:Check out this episode of Andy's Auto Sport TV where we explain all the basics about headers. In the video, we explain why headers open up horsepower gains and explain the difference between different types of headers. We also show how to install headers and then show the resulting horsepower gains with our dyno run results!
Fits On:
65-73 Cougar 289/302, 65-73 Mustang 289/302
Description:
JBA long tube headers are the number one choice for maximum performance gains and high RPM efficiency. These long tube designs are dyno and race proven to deliver the greatest possible increase in horsepower and torque throughout the RPM range. All JBA long tube headers feature large mandrel-bent stainless steel primary tubes, oversized exhaust ports, extra thick 3/8” one piece flanges, and patented JBA Firecone (standard on 4-1 long tube V8 applications. Not available on Tri-Y headers) merged collectors for smooth flow. Each system is designed to give the maximum amount of ground clearance possible so lowered cars do not drag the collectors on speed bumps. Each system includes high quality hardware and thorough instructions for a professional no-leak installation.
JBA Long Tube Features:
-3/8’ thick CNC laser-cut flanges
-Patented JBA Firecone® merged collector
-02 sensor provisions
-Large diameter mandrel-bent stainless steel primary tubes
-Oversized exhaust ports
JBA Long Tube Benefits:
-Prevents leaks caused by warping
-Increased hp/tq, improved exhaust scavenging
-Standard on EFI headers for proper connection
-Maximum flow and high RPM efficiency
-Accommodates ported cylinder heads
For years, JBA's Mid-length headers have been a favorite of classic Mustang builders and restorers. Praised for big power gains, easy installation, heavy-duty construction and no loss in ground clearance, these headers have no equal. The mid-length 1-5/8" primary tubes deliver excellent flow for high output engines. Extra thick 3/8" CNC laser-cut flanges on the head and collector prevent leaks caused by warping. These headers also feature JBA's patented Firecone® merge collector for improved exhaust scavenging and reduced turbulence in the exhaust system. Each kit includes high quality hardware and gaskets for a professional installation and starter tubes to mate to your existing system. With so many quality features and benefits, it's no wonder JBA mid-lengths are preferred for high caliber vehicles.
Header Features:
-3/8" thick laser-cut single piece flanges
-1-5/8" Mandrel-bent stainless steel primaries
-Patented JBA Firecone® merge collector
-JBA sealing dome connection with exhaust
-Premium quality hardware and gaskets
-Simple installation
-Lots of ground clearance
-Optional ceramic coating (thermal barrier)
-50 state smog legal for most applications
Header Benefits
-Increase hp & torque throughout RPM range
-Improved throttle response
-Reduced back pressure
-Reduced under hood temperature
-Increased passing power
-Increased low-end torque
-Makes engine more sensitive to other modifications (cam, intake, etc.)
-Improved engine compartment appearance

Q: How do you install a header?
A: A header is a direct bolt-on. Simply remove the factory OEM exhaust manifold and the aftermarket header is put in its place. The header is to be attached the head of your vehicle. Remove all the bolts that hold the flanges in place and detach the factory manifold. The down pipe or exhaust pipe should be removed as well and then reattached once the header flanges are bolted back onto the head.
Q: What are the different tubing options for headers and what is the difference between them?
A: There are two major designs for headers: the 4-2-1 design and the 4-1 design. In many cases 4-1 headers are designed for racing applications where the vehicle is being driven at or near redline. The 4-1 design maximizes top end power, whereas the 4-2-1 evenly distributes it throughout the power band. Either way, you're going to be getting more horsepower from a header.
Q: How much does the material used to make the header matter?
A: There are two main materials that headers are manufactured out of: ceramic and stainless steel. Ceramic headers are less expensive, but are prone to cracking if they get to be extremely hot. Stainless steel headers are more expensive but are more durable and generally more stylish. Stainless steel headers can take any kind of heat you throw at it and not prone to cracking.
Q: What does a header do? Why buy a header?
A: An exhaust header is a performance product that replaces your factory exhaust manifold and improves an engine's performance by allowing air to flow more freely. The easier an engine breathes the more power it produces. Headers generally use piping with a wider diameter than factory tubing, which allows more air to pass through the exhaust system than factory. A header is one of the easiest bolt-on modifications you can make to increase horsepower, making an effective use of money if your goal is to quickly gain horsepower.
Q: For which vehicles is it necessary to buy a pair of headers? On your website are headers automatically sold in pairs for these vehicles?
A: When purchasing exhaust headers for a V-6 or V-8 engine, the header package is complete with two headers. If your vehicle is a 4-cylinder, there only a single header that is used.
