Construction & Design

The Vulcan Series Axle-Back Exhaust System is constructed from premium 304 stainless steel, known for its corrosion resistance and long-lasting durability. The 2.5″ mandrel-bent tubing maintains consistent diameter throughout bends, optimizing exhaust flow and minimizing restrictions. The high-flow muffler is also crafted from 304 stainless steel, ensuring it withstands heat and harsh conditions while delivering a robust sound.

Advanced computer-aided design technology was employed to create a system that fits perfectly with the Jeep Wrangler JK’s factory mounting points and exhaust layout. Every weld is completed using MIG welding techniques, providing superior strength and a clean finish that stands up to off-road vibrations and extreme environments.
