JBA started with a clean sheet of paper when designing the new Cat4ward® Headers for the Titan's powerful 5.6L. Extensive development and dyno time yielded huge gains in both torque and horsepower over the restrictive factory manifold. These headers don't just make power, they are built to last. JBA's bullet proof design features a thick 3/8" one piece head flange leading into the heavy-wall 1-5/8" stainless steel primaries tubes and ends with the patented JBA Firecone® merge collector. This design reduces back pressure and helps scavenge the spent gasses exiting the engine giving you increased power and efficiency. Like all JBA products these headers are backed by our limited lifetime warranty.

- Fits all 04-08 Nissan Titan & Armada w/5.6L V8 engine
- Dyno result of 23HP/17LB-FT gain was tested with both headers and JBA exhaust system combined.
