Headers 1-7/8in Primary w/Catted Leads

The Stainless Works Headers 1-7/8in Primary with Catted Leads represent a premium long-tube header solution engineered for 2018–2021 Jeep Grand Cherokee Trackhawk models with Gen III Hemi engines. This complete header kit combines 1.875-inch primary tubes with a 3-inch collector and integrated catalytic converters, delivering increased exhaust scavenging while maintaining emissions compliance. The stainless steel construction resists thermal corrosion and provides durability in high-temperature underhood environments where cast iron alternatives fail prematurely.

Long-tube headers optimize exhaust flow by routing gases directly from the cylinder head rather than through the factory manifold, reducing backpressure and allowing the engine to breathe more efficiently. The 1.875-inch primary diameter is sized to match the displacement characteristics of the 6.2L Hemi, balancing velocity and volume across the RPM band. Included hardware and converters eliminate guesswork during installation, and the natural stainless finish withstands extreme heat cycles without degradation. Total system weight comes in at 53.53 lbs, a consideration for chassis tuning and weight distribution on performance-oriented vehicles.

This header kit serves owners pursuing measurable performance gains from their Trackhawk platform—whether for dyno testing, track driving, or comprehensive engine optimization. The catalytic converter integration ensures compliance in jurisdictions requiring emissions equipment while capturing flow benefits normally associated with catted headers. Builders upgrading fuel management, cam timing, or induction systems will find these headers a core component in maximizing Hemi power delivery. Fitment is specific to Mopar Gen III Hemi architecture in 2018–2021 Grand Cherokee models, so confirm compatibility with your exact VIN before purchasing.
