3-Into-1 Long Tube Headers

The Doug Thorley THY-465-L-C long tube headers are engineered to enhance the power output of your 1998-2004 Nissan Frontier, Pathfinder, or Xterra equipped with a 3.0L or 3.3L engine. These headers feature a 3 into 1 configuration with 1-1/2" diameter, 14-gauge steel primary tubes and a 1-3/4" collector diameter that connects to the factory flange. The headers are finished in a silver ceramic coating for durability and a sleek appearance. While they are noted as a performance upgrade for increased power, it is important to note that these headers are for race-use only and are not street legal for pollution-controlled vehicles in California. They do not include reducers, a Y-pipe, or catalytic converters, and require the reuse of factory gaskets.
