Unlock significant horsepower and torque gains for your 1968-1979 AMC Javelin. Doug’s Headers are meticulously designed and tuned for your specific vehicle, ensuring optimal exhaust flow and reduced pumping losses. Each header is crafted with 3/8″ thick machined flanges and CNC mandrel-bent 16-gauge tubing for a precise fit and superior durability.

The long-transition collectors and full-length design work together to minimize backpressure, especially at higher RPMs, giving you that crucial power boost when you need it most. The tubes are pre-polished for a sleek finish before being coated in a durable, high-temperature black for long-lasting protection and a custom look.

Engineered for models equipped without A/C, these headers fit a wide range of AMC V8 engines including the 290, 304, 343, 360, 390, 401, and more. Please note, these headers are intended for off-highway use only and may not be legal for sale or use in California or states adopting California emissions standards.

Upgrade your Javelin with Doug’s Headers D103-B and feel the difference in power and responsiveness. Built for performance and longevity, they are the perfect addition for any enthusiast seeking to maximize their vehicle’s potential.
