Construction & Design
The Vulcan Series Cat-Back Exhaust is crafted from premium 304 stainless steel, known for its corrosion resistance and longevity. The 2-1/2" tubing is mandrel bent to maintain consistent diameter throughout bends, promoting unrestricted exhaust flow and reducing backpressure. This results in improved engine efficiency and responsiveness.
Each weld is completed using 100% MIG welding techniques, providing superior strength and durability to withstand harsh driving conditions. The quad polished exhaust tips not only enhance the visual appeal but are also designed to resist discoloration and corrosion over time.
Performance & Sound
This exhaust system is engineered to optimize exhaust flow, which can contribute to improved throttle response and a more engaging driving experience. The high-flow mufflers deliver a smooth, deep tone that enhances the Jeep’s natural engine sound without being overly loud or droning during highway cruising. This balance makes it suitable for both daily driving and spirited off-road use.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
