Headers are widely believed to be one of the best performance values available today--so why put stock manifolds on your trick ride? After dropping a different engine into your project vehicle, help it produce more horsepower and fuel economy with these specialty and engine swap headers from Hedman. They feature durable 18-gauge steel construction and have thick 1/4 in. flanges for a long-lasting, leak-proof seal. 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. Special warning regarding Hedman painted headers only. The paint on these headers is not designed as a final finish; it is designed to protect the headers after the manufacturing process and during shipping. This paint will not withstand the high heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high heat paint or coating designed for use on headers be applied.
