If you have a 3FE equipped Land Cruiser and are looking to maximize it’s
performance. If you have spent the effort to build a 2FE Hybrid engine, or
you’re simply a “motor head” and want your 3FE to perform to it’s ultimate
potential, here is where to start. Our Tuned, Ceramic coated, equal length
headers are one of the most effective modifications you can make. Our
headers will maximize the performance and efficiency of any 3FE engine. This
is one of the very rare modifications you can perform on your 3FE engine
that will deliver
improved performance and efficiency at every rpm, and every throttle
position.

Our flanges are ground to a thickness of .5925” to match the OEM intake
manifold. The fact that our flanges are over ˝” thick steel negates any of
the typical problems associated with headers that use thin flanges that are
prone to warping and leaking. By using a flange that is flat on the gasket
contact surface, we are able to use the OEM manifold gasket with these
headers.
Our primary tubes are 1-3/8” ID. The reason we chose these dimensions is the
basic design of the 3FE engine. These engines are designed to produce low to
mid range torque, and our headers are designed to maximize this type of
torque curve. From the immediate application of throttle at idle, all the
way to the limit of the rpm band our headers improve performance and
efficiency.
Specific built for your FJ62. Although our headers will fit any 3FE engine,
regardless of the body configuration it is in, we designed our headers to
fit within the confines of the 62 series engine compartment. Our connecting
pipes available in bare steel or ceramic coated steel, connect directly to
your OEM catalytic convertors in their OEM location , and will remount your
O2 sensors in their stock location, using stock gaskets. Your EGR pipe will
also directly reconnect to our headers. Basically all your emission
equipment can
stay connected if you so desire. We also offer weld on connecting flanges
for those that want to run these headers on other body style vehicles or
want to custom build their own exhaust.
Ceramic coating for heat retention. Although ceramic coating tends to
improve the looks of our headers the technical purpose is to help keep the
exhaust heat in the exhaust system, not radiating into the engine
compartment. Headers by the nature if their design have more surface area
than the cast iron manifolds they replace. More surface area equals greater
heat transfer potential. Ceramic coating slows this transfer and helps keep
the heat in the exhaust system, which improves catalytic convertor
efficiency.
3FE headers are sold as a kit that includes a new manifold gasket, and
hardware for the lower connector flanges. Our connecting pipe kits include
either bare steel or ceramic coated pipes, seal ring gaskets for the pipes
to OEM Catalytic convertors, new oxygen sensor gaskets, and bolts for the
pipes to the cats.

off-road use only. They are not intended for use in lieu of factory emission
control devices, and they are not legal for sale or use in California on
pollution controlled vehicles.
