Construction & Design

Crafted from premium stainless steel, these headers and mid pipes are built to withstand the rigors of high-performance driving while resisting corrosion over time. The 1-7/8" primary tubes are mandrel-bent to ensure smooth transitions and maximize exhaust gas velocity, reducing backpressure for improved engine efficiency.

Fully TIG welded joints provide superior durability and a clean, polished appearance. The integrated high-flow catalytic converters in the mid pipes balance emissions compliance with performance gains, while the 3" lead pipes allow for easy connection to existing exhaust components or Stainless Works systems.

Performance & Sound

Replacing restrictive factory manifolds and mid pipes, this long tube header and mid pipe system significantly improves exhaust scavenging and reduces backpressure. The result is a noticeable increase in horsepower and torque throughout the RPM range, enhancing acceleration and overall engine responsiveness.

Additionally, the system produces a richer, more aggressive exhaust tone that enhances the iconic HEMI sound without introducing excessive cabin drone, making it suitable for both street and track environments.
