Coated Headers - Pontiac V8 326-455

Doug's Headers Coated Headers for Pontiac V8 326-455 are full-length, ceramic-coated exhaust manifolds designed to enhance flow and performance on classic GM A-Body vehicles from 1964–1972. These headers are ideal for restomod builders and street performance enthusiasts looking to improve their vehicle's drivability while maintaining a classic aesthetic.

Featuring 1.875-inch primary tubes that optimize scavenging across the Pontiac V8 displacement range, these headers converge into a 3.5-inch collector for efficient exhaust exit. The ceramic coating not only protects against corrosion and heat but also helps maintain lower underhood temperatures, which is crucial in tight engine bays. Constructed from durable steel, these headers replace restrictive factory cast-iron manifolds, improving exhaust flow and overall engine performance.

These headers are particularly beneficial for Pontiac V8 restoration projects, allowing enthusiasts to tune their Tempest, LeMans, or Grand Am for both weekend cruising and spirited acceleration. With installation including all necessary gaskets and hardware, these headers provide a straightforward upgrade that enhances both performance and reliability.
