JBA Cat4Ward Header 03-08 RAM 5.7L HEMI Primary Silver Exhaust

Description

Product Overview

The JBA Cat4Ward Primary Silver exhaust header is a performance‑focused component designed specifically for 5.7L HEMI engines. Constructed from mandrel‑bent stainless steel tubing, the header ensures optimal airflow with minimal restriction. The patented JBA Firecone collector creates a smooth transition for exhaust gases, reducing turbulence and improving scavenging. Factory‑style emission connections simplify installation, while extra‑thick collector domes add structural rigidity. CNC laser‑cut flanges, 3/8 inch thick, feature oversized exhaust ports that accommodate larger diameter piping, enhancing both sound and power. Dimensions measure 20 x 10 x 5.5 inches and the unit weighs 20 pounds, making it a robust yet manageable upgrade.

Usage

This header is ideal for street enthusiasts seeking a noticeable torque increase and a refined exhaust note, as well as track drivers who demand consistent performance under high‑load conditions. It fits perfectly on 2006‑2014 RAM 5.7L HEMI trucks and SUVs, delivering improved throttle response during acceleration and better fuel efficiency on cruising. The durable ceramic exterior resists corrosion from road salt and harsh climates, ensuring longevity whether the vehicle is used daily or stored in a garage for occasional track days.

FAQ

Will this header fit my 2008 RAM 5.7L HEMI?

Yes, the Cat4Ward Primary Silver header is engineered to bolt directly to the factory‑mounted exhaust manifolds on 2006‑2014 RAM trucks equipped with the 5.7L HEMI engine.

Do I need to modify my exhaust system after installation?

The header includes oversized ports and factory‑style connections, so most users can pair it with standard mid‑pipe and muffler components without additional modifications.

How does the firecone collector affect sound?

The firecone design smooths exhaust pulse flow, producing a deeper, more refined tone while still delivering the aggressive note expected from a performance header.
