Upgrading to aftermarket headers is a popular choice among enthusiasts looking to improve the performance and sound of their 318 engine. Here's a guide to help you choose the right headers:
Header Design:
Consider the different header designs available for the 318 engine, including shorty headers and long-tube headers. Shorty headers offer easier installation and better ground clearance, while long-tube headers provide enhanced performance gains at higher RPMs. Choose a design that aligns with your performance goals and vehicle application.
Material Construction:
Evaluate the material construction of the headers. Stainless steel headers offer durability, corrosion resistance, and thermal stability, making them ideal for high-performance applications. Mild steel headers are more budget-friendly but may be prone to rust and corrosion over time. Choose headers made from quality materials for long-lasting performance.
Header Diameter and Primary Tube Length:
Pay attention to the diameter and length of the header primary tubes. Larger diameter tubes and longer primary lengths improve exhaust flow and scavenging efficiency, resulting in increased horsepower and torque. Consider the intended use of your vehicle and engine specifications when selecting the optimal header diameter and primary tube length.
Coating Options:
Consider the coating options available for headers, such as ceramic coating or high-temperature paint. Ceramic coating improves thermal insulation, reduces under-hood temperatures, and enhances durability, making it a popular choice for performance headers. High-temperature paint provides basic corrosion resistance and aesthetic appeal.
Brand Reputation:
Choose headers from reputable brands known for manufacturing high-quality performance components. Research customer reviews, testimonials, and professional recommendations to gauge the reputation and track record of different header brands. Select headers from manufacturers with a history of producing reliable and proven products.
Installation Considerations:
Factor in the installation requirements and compatibility with your vehicle's exhaust system. Some headers may require modifications to the exhaust system or engine bay for proper fitment. Consider professional installation if you're not familiar with exhaust system modifications or header installation procedures.
In conclusion, selecting the right headers for your 318 engine involves considering header design, material construction, diameter and primary tube length, coating options, brand reputation, and installation considerations. By evaluating these factors and choosing headers that suit your performance goals and vehicle application, you can enhance the power, sound, and driving experience of your 318-powered vehicle.
