    FlowTech's Shorty Truck Headers are the perfect starting point to customize your 2WD or or 4WD vehicle! Simply remove the restrictive factory exhaust manifolds and bolt these headers in their place. They will bolt directly to your factory or OE-style exhaust, giving you more power and better fuel economy. Mandrel-bent 16-gauge steel tubes along with extra thick 3/8" exhaust flanges provide a reliable header with a leak-free seal! These headers connect to all factory emissions equipment and include necessary hardware and gaskets.


    Features
  • 3/8" exhaust flanges
  • Mandrel-bent 16-gauge tubing (.049" thick)
  • Direct replacement for OE exhaust manifolds
  • Complete with premium gaskets and hardware
  • Accommodates all factory emissions-control devices
