The headers shown for Toyota V6 and V8 truck engine conversions are designed to fit in a tight area. This allows maximum air flow between the header-to-the-body area while slightly increasing the truck’s performance. Our headers solve most exhaust hook-up problems and greatly reduce under-hood temperatures caused by using a factory-cast manifold in a different chassis than it was designed for. A body lift is recommended for proper clearance on all headers and will maximize air flow during low speed driving.

NWOR’s GM V8 swap headers features long 1-5/8” primary tubing creating big gains in low and midrange torque. The GM V8 header features heavy 3/8” flanges with O-ring sealing, 14 gauge tubing and NWOR “no gasket, no leak” ball joint connectors. These ball joints ensure ease of installation, and they allow severe engine movement in the chassis without causing header breakage or gasket leaks. This header offers maximum horsepower gains, best fit and clearance over any V8 conversion header sold. Many customers have told us “wish we had bought it the first time around - we really can feel the performance difference.”
