STRATEGY
In keeping with our goal of providing our customers with the best possible value, we have tested a large group of components specifically designed for the Dodge 4.7 liter v8 vehicles.
We have invested many hours evaluating and refining each of the Dodge 4.7 liter v8 vehicles products on our MD Chassis “dyno”, to ensure that we could develop as much power as possible, as safely as possible.
The site menu on the left side of this page, lists the clear winners when it comes to “performance vs. dollar” value. Please check back often as we are always developing new ways to create more horsepower.

NEW Power Options, NEW Exhaust Options, Guaranteed Savings !
JBA CAT4WARD C.A.R.B. Legal Headers
JBA CAT4WARD C.A.R.B. Legal Headers improve efficiency and increase the airflow of the factory exhaust by up to 30% over factory exhaust manifolds.
This translates into increased pulling torque and free-reving horsepower. In fact, tests performed
for the C.A.R.B. show that vehicles equiped with JBA Shorty Headers run cleaner than originally
equipped vehicles.
When upgrading to a set of JBA Headers you will improve the acceleration, throttle response, and even the
fuel economy of your vehicle. You will also make the engine more sensitive to subsequent modifications
such as aftermarket intake systems, camshafts, cylinder heads, and especially superchargers.
This JBA CAT4WARD Kit Includes
- Flanges are cut from 3/8" thick plate to eliminate distortion and potential leaks
- Heavy wall 14 gauge stainless steel tubing for longevity
- 1 5/8 in.Primary Tube Diameter
- Y-pipe, Bolts, Studs, Gaskets Included
- All JBA CAT4WARD Headers are C.A.R.B. Legal
