aFe Powers Race Only Twisted Steel Headers for the Toyota Tacoma V6-4.0L deliver an astounding 9 Hp and 12 lbs. x ft. torque while out flowing the factory exhaust manifolds. The headers are constructed of 1-5/8 in. 16-gauge 409 stainless steel tubing with 3/8 in. thick CNC Laser cut flanges to ensure a leak-free seal. To eliminate dead space that can cause turbulence and hinder flow that formed s are prone to produce, a mitered merge and optimized tube lengths are used for true pulse control technology improving flow and performance. The smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. Each header comes with a 200 cell, metallic high flow catalytic converter. All components are supplied for a hassle-free bolt-on and go installation with no modifications necessary.
