JBA 1.5" FJ Cruiser Cat4ward Shorty Headers; Stainless 10-11 FJ Cruiser


Ditch your tired, restrictive, inefficient stock exhaust manifold and let your engine breathe freely with performance headers. JBA Cat4ward Headers unlock your motor's power potential for unrestricted, white-knuckle performance gains.

The Achilles heel for engine performance is the exhaust. With JBA Headers, you get a boost of up to 10-25 tire-turning horses out of your motor. The steel tubing is mandrel-bent with extra-large exhaust ports and a leak-free, laser-cut 3/8" thick flange for fast exhaust flow.

You also get JBA's patented Firecone merge collector (depends on model), which quickly moves spent gasses out through your tailpipe. JBA exhaust headers let your engine breath easier, giving you more power, torque and throttle response.

All mounting hardware is included for a do-it-yourself install that doesn't void your factory warranty. 4 finishes to choose from. Of course, your JBA Headers come with a 1-year warranty.
