Review DOUGS Coated Headers Pontiac fits CATALINA 1965–1968

Introducing Doug's D521 Coated Headers for the 1965, 1966, 1967, and 1968 Pontiac Catalina models equipped with 326-389-400-455 engines. These headers are not just an upgrade, they are a statement of passion for your classic Pontiac and a testament to your commitment to performance.

Doug's D521 Coated Headers are crafted from premium 304 stainless steel, ensuring durability and resistance to corrosion. The headers feature a 1 7/8-inch primary tubing, which is designed to maximize exhaust flow and scavenging, resulting in improved engine performance and throttle response. The tubing is mandrel-bent, ensuring a smooth internal radius that prevents restrictive bends and maintains optimal exhaust flow.

The D521 Coated Headers are equipped with a high-quality ceramic coating. This coating not only gives the headers a sleek, polished appearance but also provides excellent heat insulation, protecting the surrounding engine components from excessive heat. The ceramic coating is also highly resistant to corrosion, ensuring that your headers maintain their appearance and performance over time.

The D521 Coated Headers are designed to fit seamlessly into your Pontiac Catalina's factory exhaust system. They are available in a standard length, which is compatible with the majority of Pontiac Catalina models. However, if you require a custom length, Doug's offers a custom fitting service to ensure a perfect fit for your vehicle.

Installing the D521 Coated Headers is a straightforward process. The headers come with all necessary hardware, including new gaskets and bolts, making installation easy and hassle-free. Doug's also provides detailed installation instructions to guide you through the process.

In conclusion, Doug's D521 Coated Headers are an excellent upgrade for your 1965, 1966, 1967, or 1968 Pontiac Catalina.
