The 3.4L V6 Tacoma has been a favorite among off-road and sport truck enthusiasts for years. The clean design of the truck combined with the impressive durability of the engine and chassis makes it a great fit for a variety of applications. Unfortunately, the power potential of 3.4L V6 was limited by the restrictive "log" style exhaust manifolds. JBA's engineering team created the ultimate exhaust solution for the 3.4L with this trick Cat4ward Header system. Designed to increase the flow out of the engine with smooth individual primary tubes, true collector merges, and a matching Y-pipe. The result is a significant increase in both torque and horsepower throughout the RPM range. Whether you've got a tight handing supercharged S-runner or a lifted TRD Prerunner - JBA has the best header system for your power needs!
