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:
1996 Jeep Cherokee 4.0L, 91-95 Jeep Wrangler 4.0L, 96-99 Jeep Wrangler 4.0L, 97-98 Jeep Cherokee 4.0L
Description:
With more power, quicker acceleration and tougher construction than ever, the new Banks Revolver® for the Jeep 4.0 liter ('91 to '99) out muscles any competitive exhaust manifold: period! You'd think that being made from super-durable, mandrel-bent 409 stainless steel tubing and sporting a ½"-thick precision ported and machined flange was enough... but there's more. The header is fortified with a "revolver" collector which features Banks' patented "Power Pickle®" exhaust collector technology. The Revolver manifold features a longer center tube in the 6 cylinder exhaust collector which captures exhaust pulse action and turns it into massive torque throughout the operating range. Powering through the roughest terrain is no longer a question. (For 2000-06 manifolds go here)
And cracking... a thing of the past when you arm your Jeep with Banks TorqueTubes.
Banks TorqueTube Manifolds feature:
Non-deforming manifold outlet seal
Self-aligning exhaust seal will never compress or blow out • Bolts easily to stock exhaust
"Revolver" Collector
Banks' patented collector design with extended center tube is designed to pull the exhaust pulses from the engine for crisp throttle response on the draw
Manifold tubes fully welded
Each tube is welded to the flange twice, inside and out
Super-duty manifold flanges
1/2"-thick flanges never warp or crack • Computer-controlled machining • Precision port-match to cylinder head
Unrestricted Exhaust Ports
Tubes sized and shaped to match cylinder-head exhaust port
Precision-milled manifold flange
Milled dead-flat after welding, for durability and a perfect seal every time
Stainless Steel
Sustains exposure to ultra-high temps for superior durability • Mandrel-bent tubing for better airflow

Banks is one of the premier names in turbocharged diesel modification, but there is a lot more to the company than just that. Banks engines have been used everyone from NAVY Seals to winners at the Bonneville salt-flats.
Banks' name precedes him and it is no coincidence that he teaches to graduate students of the General Motors Institute. Banks' engineering spirit has allowed him to innovate great things, such as the twin-turbo small block Chevy in the late 1970's.

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: 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.
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: 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: 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.
