Tubular headers are designed to exchange the inceptive pitch iron manifolds that most trucks are manufactured with. Pull the manifolds out of the engine bay. Spray gasket remover on the header mounting surface and remove any gasket residue and oil.Installing the Headers
Once you have cleaned the header mounting surface, place the headers into the engine bay against the motor.
Tools and Supplies
Before installing headers on your Motor lorry, you Testament extremity To collect some tools and supplies for the profession. In establishment to lift the vehicle, you Testament extremity a jack and a establish of jack stands or all the more a full-sized vehicle lift.

Moreover, the Rugged casting of cast iron manifolds interrupts the smooth flow of air as spent exhaust gasses Way out the Engine. Tubular headers enjoy larger exhaust passages and smoother bends and surfaces that embolden efficient air flow, increasing horsepower and torque.
Be sure to install new gaskets, also. You can use a couple of pieces of small tape to hold the gaskets in place while you install the headers. Hand tighten the header bolts.
