Exhaust Manifold Dorman Right Side Upgrade Design

Description

Product Overview

The Dorman 674-498 right‑side exhaust manifold is engineered specifically for select Jeep Wagoneer and Ram 1500 vehicles. Constructed from high‑strength steel, the manifold arrives ready to paint, allowing seamless integration with factory finishes. Key innovations include an integrated upper flange that reinforces the side walls, a thicker lower flange for added rigidity, and a ceramic coating that ensures uniform heat distribution across the exhaust path. Dimensions measure 19.5 x 8.6 x 5.6 inches and the unit weighs 15.5 pounds, making handling straightforward during installation. The part carries the OEM number 68591572AB, guaranteeing a direct fit where the original component has warped, cracked, or failed.

Usage

This exhaust manifold is ideal for drivers who demand reliable performance from their heavy‑duty trucks and SUVs, especially in demanding conditions such as towing, off‑road adventures, or high‑temperature engine operation. By replacing a compromised OEM manifold, owners can restore proper exhaust flow, reduce back‑pressure, and protect the cylinder deactivation system from thermal cycling damage. Installation is suited for both professional mechanics and experienced DIY enthusiasts.
