Construction & Design
The aFe Vulcan Cat-Back Exhaust is constructed from premium 304 stainless steel, known for its corrosion resistance and longevity under harsh conditions. The tubing is mandrel-bent to maintain consistent diameter and smooth exhaust flow, which reduces restrictions and enhances performance. The system’s high-flow transverse muffler features an integrated X-pipe and crossover balance tube, engineered to optimize exhaust pulse distribution and minimize unwanted drone during cruising.
Polished quad exhaust tips not only provide a striking visual upgrade but are also clamp-on for easy installation and maintenance. The entire system is 100% MIG-welded, ensuring robust joints that withstand the rigors of off-road use and spirited driving.
Performance & Sound
This cat-back exhaust system significantly improves exhaust flow, resulting in enhanced throttle response and a more aggressive engine sound. The integrated X-pipe and crossover balance tube design promote efficient scavenging, which helps to maximize power output while reducing exhaust drone at highway speeds. The factory-style valves allow the system to switch between a quieter mode for daily driving and a louder, more aggressive tone when performance mode is engaged, delivering versatility for all driving conditions.

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!
