    You absolutely will not believe the quality of these painted long tube headers. The musclemaxx headers feature 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 painted headers will bolt straight up to the Dynatech® MuscleMaxx dual exhaust kit.

    Fits: 1967-69 Camaro
