What the JBA Headers Do

The factory exhaust manifolds on the 4.7L are restrictive. JBA Cat4ward headers replace them with mandrel bent primary tubes, 3/8" one piece laser cut flanges and JBA's patented Firecone collector, and JBA quotes dyno gains of 25+ hp and 38 lb-ft. The result is more torque low down and more power at the top, which is what a V8 Tundra that tows or hauls needs. These are shorty headers, not long tubes.

They are built to work with the truck's factory emissions equipment, are CARB certified and 50 state smog legal, and carry JBA's limited lifetime warranty. Each kit comes with hardware, gaskets and instructions for a bolt on, do it yourself install.

Pick by Year and Finish

Sequoia owners: the same four kits are listed for the 4.7L Sequoia, split at the same point between 2004 and 2005, so pick by model year the same way.

The stainless kits use 409 stainless primaries. The silver ceramic kits add a polished ceramic coating rated to 1600 degrees, which keeps heat in the exhaust and out of the engine bay and keeps the headers looking new.

Finishing the Exhaust

A header works best with a free flowing exhaust behind it. Cat back systems, mufflers, catalytic converters and gaskets for this truck are in the 1st gen Tundra exhaust section.

Tundras With the 3.4L V6

Not every 1st gen Tundra has the V8. If yours has the 3.4L 5VZ, these headers will not fit and no V6 header is listed on this page; contact our tech team before ordering. The 3.4L does have its own supercharger kit, and everything else for the truck is in the 2000 to 2006 Tundra catalog.
