aFe MACH Force-Xp Cat-Back Exhaust System

2015–2020 Dodge Charger & 2015–2023 Dodge Challenger 6.2L Hellcat / 6.4L 392

Part #: 49-32070NM

Overview

The aFe MACH Force-Xp Cat-Back Exhaust System (without muffler) is engineered for Dodge Charger and Challenger models equipped with the 6.2L Hellcat and 6.4L 392 engines from 2015 through 2023. Designed for enthusiasts seeking an aggressive exhaust tone and enhanced performance, this system replaces the factory cat-back exhaust with a durable, high-flow alternative that maximizes exhaust flow while maintaining a direct bolt-on fitment.

Ideal for drivers who want to unleash the full potential of their muscle car’s powertrain, this exhaust system delivers a deep, aggressive sound signature without the drone commonly associated with aftermarket setups. It is a perfect upgrade for those looking to improve throttle response and exhaust scavenging while preserving factory-style exhaust valve operation.

Key Features

This cat-back exhaust system incorporates advanced design elements and premium materials to ensure superior performance and durability:

• Constructed from 3" mandrel-bent 304 stainless steel tubing for maximum strength and corrosion resistance
• Utilizes factory-style hangers for a secure, direct bolt-on installation with no cutting or modifications required
• Includes factory-style exhaust valves that operate using the factory valve motors (not included), allowing for controlled exhaust flow based on throttle position
• Features an integrated mitered merge X-pipe to balance and evenly distribute exhaust pulses, reducing drone and enhancing scavenging
• Incorporates a crossover balance tube to equalize exhaust pulses, further minimizing drone and improving sound quality
• 100% MIG-welded construction for race-proven strength and durability
• Designed using computer-aided design (CAD) technology for precise factory fitment and optimal performance
• Includes all necessary hardware for a hassle-free installation process

Construction & Design

The aFe MACH Force-Xp Cat-Back Exhaust System is crafted from premium 304 stainless steel, known for its excellent corrosion resistance and long-lasting durability. The 3-inch mandrel-bent tubing ensures smooth exhaust flow with minimal restrictions, enhancing both performance and sound quality. The system’s design incorporates a mitered merge X-pipe and a crossover balance tube, which work together to balance exhaust pulses and reduce unwanted drone, delivering a refined yet aggressive exhaust note.

Every joint is 100% MIG-welded to provide superior strength and reliability, making this exhaust system suitable for both street and track use. The use of factory-style hangers and exhaust valves ensures that the system integrates seamlessly with the vehicle’s existing components, maintaining the factory look and function.

Performance & Sound

This cat-back exhaust system is engineered to improve exhaust scavenging, which can enhance throttle response and overall engine efficiency. The integrated X-pipe and balance tube design minimize exhaust drone, providing a deep, aggressive exhaust tone that is both powerful and refined. The factory-style exhaust valves allow for dynamic control of exhaust flow, enabling a quieter operation during cruising and a more aggressive sound under heavy throttle.

Installation & Fitment
