Dynatech SuperMAXX headers incorporate the latest in racing exhaust technology for increased horsepower and torque. They feature all T-304 stainless steel construction for strength and durability, along with CAD-designed Aero-flow collectors. Header gaskets and bolts are included. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom altered parts, then it is the installer's responsibility to verify fitment.
