These tuned length headers from BBK are designed to optimize their scavenging effect, helping to extract exhaust gases from your cylinder for increased performance. These CNC-machined headers feature mandrel-bent, heavy-gauge tubing and a custom high-flowing cast merged chamber. All gaskets and hardware 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.
