• Direct bolt-on installation requiring no cutting, welding, or modifications
• Engineered using computer-aided design (CAD) for precise factory fitment and performance optimization

Construction & Design

The aFe Large Bore-HD DPF-Back Exhaust is crafted from premium 304 stainless steel, known for its superior corrosion resistance and strength under high-heat conditions. The 3-inch mandrel-bent tubing ensures smooth exhaust flow by maintaining consistent diameter through bends, reducing turbulence and backpressure. This results in improved engine efficiency and responsiveness.

The polished 4-1/2" stainless steel exhaust tip not only adds a sleek, high-end aesthetic but also features a laser-etched aFe POWER logo, underscoring the system’s quality and brand heritage. The entire system is 100% MIG-welded, providing race-proven durability and a robust structure that withstands the rigors of daily driving and off-road use.

Performance & Sound

By replacing the restrictive factory muffler and exhaust piping from the DPF back, this system enhances exhaust flow, which can improve throttle response and reduce exhaust gas temperatures. The intercooled tubing design further aids in managing heat, contributing to consistent performance during demanding driving conditions.

The exhaust note is refined and aggressive without being overly loud, delivering a deep, sporty tone that complements the Jeep Wrangler’s rugged character while maintaining comfort for daily driving.
