Construction & Design
The Vulcan Series axle-back exhaust system is crafted from premium 304 stainless steel, known for its corrosion resistance and strength under extreme conditions. The 2.5" mandrel-bent tubing maintains consistent diameter throughout bends, maximizing exhaust flow and minimizing turbulence. This results in improved performance and a more efficient exhaust cycle.
The high-flow muffler is engineered to balance sound and flow, delivering a deep, aggressive tone without excessive drone. The quad polished tips not only enhance the visual appeal but also resist discoloration and corrosion, maintaining their showroom shine over time. Every weld is completed using MIG welding techniques, ensuring robust joints that withstand the rigors of off-road and daily driving.
Performance & Sound
This axle-back system is designed to improve exhaust flow, which can contribute to a more responsive throttle and a slight increase in horsepower and torque. The high-flow muffler produces a rich, deep exhaust note that enhances the Jeep’s natural engine sound without being overpowering. The quad polished tips amplify the aggressive appearance and sound, making your Wrangler stand out on and off the road.

No cutting, welding, or modifications are necessary, allowing for a hassle-free installation that can typically be completed with basic hand tools. The system’s precise fitment ensures proper alignment and clearance, preserving factory ground clearance and avoiding rattles or vibrations.

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!
