Description

The Doug's Headers D453-B is engineered to deliver maximum power gains across the entire RPM spectrum for Mopar small block engines. This full-length header is crafted from robust 16-gauge steel, featuring 1 5/8-inch primary tubes and a 3-inch collector port with a 3-bolt flange. The flanges are a thick 3/8-inch and are CNC machined to prevent warping, ensuring an accurate fit and improved exhaust flow. The Hi-Temp Black Coating provides a durable, clean look that withstands high performance conditions, offering protection against rust and corrosion. This practical finish maintains a classic, aggressive style. The header includes gaskets and mounting hardware for a more complete installation. This header is specifically designed for a wide range of Mopar V8 engines from 1962-1976, including applications in Dodge Challengers, Chargers, Coronets, Darts, and Plymouth Barracudas, Cudas, Belvedere, and Dusters, typically with 318, 340, or 360 cubic inch engines. A note for installation indicates that a mini starter (PerTronix S3005P/B or Mopar P5007860AB) must be used for many applications.
