HEADER HEAVY DUTY 91-99 YJ TJ XJ ZJ

Improve the performance and durability of your Jeep's exhaust system with the Crown Automotive Stainless Steel Exhaust Header. Designed specifically for 1991–1999 Jeep Wrangler YJ and TJ, Cherokee XJ, Comanche MJ, and 1993–1998 Grand Cherokee ZJ models equipped with the legendary 4.0L inline-six engine, this high-flow header replaces the restrictive factory exhaust manifold with a performance-oriented tubular design.

Constructed from premium stainless steel, the header offers excellent resistance to corrosion, heat, and the harsh conditions encountered both on and off the road. Its optimized tube routing improves exhaust scavenging and reduces backpressure, allowing the engine to breathe more efficiently across the RPM range. The result is improved throttle response, smoother power delivery, and enhanced overall engine performance. Whether you're replacing a cracked factory manifold or upgrading your Jeep's exhaust system for improved reliability and airflow, the Crown Automotive Stainless Steel Exhaust Header delivers the fit, durability, and performance Jeep enthusiasts demand.
