Construction & Design

The exhaust system is crafted from premium 304 stainless steel tubing, mandrel-bent to maintain consistent diameter and optimize exhaust gas flow. This construction minimizes restrictions compared to the stock exhaust, allowing the engine to breathe more freely and produce better performance. The dual stainless steel mufflers are engineered to absorb high-pitched tones, resulting in a refined yet aggressive exhaust note that evolves with engine speed.

The quad exhaust tips are made from black stainless steel with a rolled edge and angled cut, providing a sleek and aggressive rear appearance that enhances the Challenger’s muscular stance. Each weld is hand MIG welded to ensure maximum strength and durability, making this system a reliable upgrade for years of use.

Performance & Sound

The aFe MACH Force-Xp Cat-Back Exhaust delivers noticeable improvements in throttle response, torque, and horsepower by reducing backpressure and improving exhaust flow. The integrated X-pipe with crossover balance tube balances exhaust pulses, which not only enhances performance but also reduces exhaust drone inside the cabin for a more enjoyable driving experience.

Sound-wise, this system offers a mild to aggressive tone that deepens as RPMs rise, providing a powerful and sporty exhaust note without being overly loud or intrusive during normal driving conditions.
