Product Description

The Stainless Works DUR18HCAT is a long tube header kit built for the Dodge Durango SRT 392 6.4L HEMI and SRT Hellcat 6.2L supercharged HEMI, featuring 1-7/8" primary tubes that are CNC mandrel bent to maximize airflow and increase power over the restrictive factory exhaust manifolds. Each header connects to a 3" slip-fit collector before flowing through a high-flow catalytic converter and 3" catted lead pipe, merging into a flanged connection point for an easy transition to either the factory exhaust or a Stainless Works aftermarket system.

Built from corrosion-resistant 304 stainless steel and TIG welded at Stainless Works' Streetsboro, Ohio facility, this header kit is engineered for lasting durability without the rust concerns of mild steel headers. Installation is a direct bolt-on process using factory mounting points and hardware, with no major modifications required. Every Stainless Works product is designed, manufactured, and dyno tested in-house to deliver proven power gains alongside a more aggressive exhaust note.

This kit is intended strictly for racing competition use -- it is not legal for street or highway vehicles, and purchase requires a signed Vehicle Compliance Waiver confirming the intended use. Backed by Stainless Works' lifetime warranty on material and craftsmanship, this header kit is the correct choice for Durango SRT 392 or SRT Hellcat owners building a dedicated competition setup.
