  • Additional Information

    Full length and fenderwell headers provide the ultimate performance for street rodders with high performance engines. These header styles have longer primary tubes, which help produce more horsepower and torque than Tight Tucks. Chassis headers fit inside the frame rails, but if there is not enough room, our "up and over" fenderwell headers will provide the same great performance with an awesome look.
