You absolutely will not believe the quality of these headers. 3/8" thick laser cut flanges give you a leak free seal. Nearly equal length step tube design just like the racers run gives you a wider powerband and more horsepower. The four bolt collecter flange is unique in that it needs to be used with the Dynatech® reducer cones. This gives you a leak free ball and socket connection that allows movement as the engine torques under acceleration.
These headers will bolt straight up to the Dynatech® MuscleMaxx dual exhaust kit.
NOTE: Reducer cones ARE included.
