RR BLACK STEEL HEADER 00-04 TJ 4.0L

Unlock additional performance from Jeep's legendary 4.0L inline-six engine with the Rugged Ridge Performance Header. Designed specifically for 2000–2006 Jeep Wrangler TJ and Cherokee XJ models, this performance header replaces the restrictive factory exhaust manifold with a high-flow design engineered to improve exhaust flow and overall engine efficiency.

By reducing exhaust restrictions and improving scavenging, the header helps the engine breathe more effectively across the RPM range, supporting improvements in horsepower, torque, and throttle response. Built from durable materials designed to withstand years of exposure to extreme exhaust temperatures and harsh operating conditions, this header is equally at home on daily-driven Jeeps and dedicated trail rigs. Designed as a direct replacement for the factory manifold, the Rugged Ridge Performance Header offers dependable fitment and performance while serving as an excellent upgrade or replacement solution for aging factory exhaust components.
