Chevy Truck Header AutoForge Polished Steel

Description

Product Overview

The AutoForge exhaust header is a precision‑engineered component designed for classic Chevrolet and GMC trucks from 1973 to 1991. Constructed from high‑grade polished steel, the header features 1 5/8‑inch primaries and 3‑inch inlet ports to maximize exhaust scavenging and improve overall engine efficiency. With a weight of 26.9 lb and package dimensions of 36 × 18.15 × 5.5 in, it balances robust construction with manageable installation size. The header is compatible with Gen 1 Small Block V8 engines ranging from 265 ci to 400 ci, covering a broad spectrum of classic powerplants.

Usage

Designed for both 2WD and 4WD classic trucks, this header excels in street performance, off‑road adventures, and custom build projects. Whether restoring a vintage C10 or enhancing a modernized Suburban, the header delivers reliable exhaust flow and a clean, polished appearance that resists rust. Minor adjustments may be required for stock‑height 4WD setups to ensure proper collector clearance, but the included gaskets, bolts, and collectors simplify the installation process for most applications.
