The WCF headers are a transformative addition to your 3800 Fiero engine swap, designed to significantly enhance the torque output within the 1500 to 5500 rpm range. This improvement in torque can lead to a more responsive and powerful driving experience.

These headers are meticulously crafted using mandrel-bent tubing, a process that ensures a uniform diameter throughout the length of the tube, thereby optimizing the flow of exhaust gases. The construction process involves TIG welding, known for its precision and strength, ensuring a robust and durable product.

You have the option to choose between two materials for your headers: 1018 steel, known for its acceptable strength and affordable price, or 304 stainless steel, renowned for its superior corrosion resistance and durability.
