Construction & Design

The aFe Rebel Series Cat-Back Exhaust is built from premium 409 stainless steel tubing, known for its excellent resistance to rust and heat. The 2-1/2" mandrel bent pipes ensure smooth exhaust flow, reducing backpressure and improving throttle response. The rear transverse muffler is coated with a high-temperature black powder finish that not only protects against corrosion but also adds a sleek, aggressive look under the vehicle.

Each weld is performed by hand using MIG welding techniques, providing superior strength and durability compared to automated welds. The dual rear-exit exhaust tips are clamp-on style, allowing for easy installation and a secure fit, while the black powder coating and laser-cut branding add a refined, custom appearance.

Performance & Sound

This cat-back system eliminates the restrictive primary muffler and replaces it with a high-flow transverse muffler, resulting in improved exhaust scavenging and a noticeable increase in exhaust flow. The design produces a moderate, aggressive exhaust tone that enhances the Jeep’s natural engine sound without being overly loud or intrusive, making it suitable for daily driving and off-road use alike.

Installation & Fitment

The aFe Rebel Series Cat-Back Exhaust is engineered for a direct bolt-on installation using all factory mounting points and hardware. The system features OE-style bayonet hangers that securely hold the exhaust in place, preventing movement and rattling during driving. No cutting, welding, or additional modifications are required, making installation straightforward and hassle-free for both professional installers and experienced DIY enthusiasts.

This exhaust system fits both 2-door and 4-door 2018–2019 Jeep Wrangler JL models equipped with the 3.6L V6 engine.
