Doug's Headers D569 Exhaust Header Set for 1967-1969 Firebird 326-455 V8 Engines

Doug's Headers D569 is an aftermarket exhaust header set meticulously engineered to enhance the performance of your 1967-1969 Pontiac Firebird 326-455 V8 engines. This header set is suitable for cars equipped with factory manual or automatic transmissions.

The Doug's Headers D569 is manufactured from high-quality stainless steel, ensuring durability and resistance to corrosion. Boasting a 1 5/8-inch primary tube diameter, these headers promote efficient exhaust gas flow, resulting in increased horsepower and torque. With a collector diameter of 3 inches, the headers provide an excellent balance between power and exhaust noise, making this an excellent choice for performance enthusiasts seeking to boost the output of their Firebird without resorting to an overly loud exhaust system.

The Doug's Headers D569 is designed with precision and functionality in mind, featuring 9 in. merge collectors that are welded to the headers to minimize exhaust flow losses. Each header comes with vacuum-activated cutouts that can be utilized for a performance sound during high RPMs. Coupled with the OEM-style laser-etched, numbered gaskets, these headers ensure a secure and precise fit every time, ensuring a hassle-free installation process.

Please note that, in addition to the Doug's Headers D569, other accessories such as catalytic converters, oxygen sensors, and the exhaust manifold may require upgrading as well for optimal compatibility. This product is considered 'used-ish' due to being previously owned but offers excellent value for enthusiasts seeking high-performance improvements at a reasonable price.
