Jeep Cherokee and Wrangler Header and Intake Install - Power TakeoverPosted in How To on October 1, 2008 0) (
With suspension and big tires in place on a 4x4, available horsepower and torque begin to wane. While lower axle gears will help restore some of the lost engine performance, many simply get used to the feeble power and acceleration and never regain what was lost. One easy, bolt-on method to take back the power is through the installation of a set of free-flowing headers, which will decrease exhaust backpressure and make it easier for exhaust gases to escape the cylinders more efficiently.
JBA headers are tuned to increase horsepower and torque throughout the rpm range.
The headers are constructed from heavy-duty, mandrel-bent stainless steel tubing and are available with an optional titanium ceramic or silver ceramic coating. They feature extra-thick, 1/2-inch laser-cut flanges and high-flow merge collectors, along with JBA's sealing dome technology. The JBA Cat4ward headers are 50-state smog legal, include necessary hardware, and offer a simple, bolt-on installation. JBA Cat4ward headers are available for '91-'06 Jeep Wrangler and Cherokee vehicles with the 4.0L I-6 engine. JBA also offers headers and complete exhaust systems for many other engine applications.
