Construction & Design

The aFe Rebel Series Cat-Back Exhaust is crafted from premium 409 stainless steel, chosen for its excellent durability and resistance to rust and corrosion in harsh environments. The 2-1/2" mandrel-bent tubing ensures smooth exhaust flow by maintaining consistent diameter through bends, reducing turbulence and backpressure.

Each weld is hand MIG-welded to guarantee structural integrity and long-term reliability. The dual muffler design strategically balances exhaust pulses, while the black powder-coated stainless steel tips provide a sleek, aggressive finish that complements the rugged styling of the Jeep Wrangler JL.

Performance & Sound

This exhaust system is tuned for a mild tone that enhances the natural sound of the 3.6L V6 engine without being overly loud or droning. The primary stainless steel muffler absorbs harsh high-frequency tones, while the rear muffler improves exhaust flow and balances pulses for a smooth, refined exhaust note. The dual rear exit configuration not only improves exhaust scavenging but also adds an aggressive visual presence.

Installation & Fitment

The aFe Rebel Series Cat-Back Exhaust is designed for a direct bolt-on installation using all factory mounting points, eliminating the need for cutting or welding. OE-style bayonet hangers securely hold the exhaust in place, ensuring a stable fit during all driving conditions. High-quality stainless steel band clamps provide a leak-free seal and simplify the installation process.

Please note this system fits 4-door Jeep Wrangler JL models equipped with the 3.6L V6 engine from 2018 through 2025.
