Review DOUGS HEADERS 64-72 Chevy Exhaust System fits CHEVELLE

Doug's Headers is a renowned manufacturer of high-performance exhaust components, and the DES103 headers are a prime example of their engineering excellence. These headers are meticulously designed for 1964 to 1972 Chevrolet Chevelle applications.

The DES103 headers are crafted from 304 stainless steel, ensuring superior strength and durability. The material's resistance to corrosion makes these headers an excellent investment for those seeking long-lasting performance upgrades.

Each header features a 1 5/8-inch primary tube diameter, which is optimized for providing an efficient exhaust flow. The exhaust gases exit via 3/8-inch collectors that merge into a 2 1/2-inch diameter exhaust pipe. The collector design ensures optimal scavenging of exhaust gases, reducing backpressure and enhancing engine performance.

The Doug's Headers DES103 exhaust system comes with standard 5/8-inch studs, making installation straightforward. The studs are threaded to accommodate various exhaust gasket materials, such as copper, steel, or gasket mates, offering flexibility to meet your specific installation requirements.

These headers are designed to work seamlessly with factory catalytic converters. However, they can also be used in conjunction with aftermarket performance catalytic converters for those seeking additional power gains.

By installing Doug's Headers DES103 on your 1964 to 1972 Chevrolet Chevelle, you can expect a noticeable improvement in engine performance. The exhaust system's efficient design allows for better scavenging of exhaust gases, reducing backpressure, and providing a smoother power delivery throughout the RPM range.
