Key Features

This cat-back exhaust system incorporates advanced design elements and high-quality materials to optimize performance and sound:

• 3" mandrel-bent 304 stainless steel tubing for maximum flow and corrosion resistance
• Dual high-flow stainless steel mufflers that reduce high-pitched tones and enhance muscle car growl
• Crossover balance tube that equalizes exhaust pulses for improved flow efficiency and reduced drone
• MIG welded construction for strong, leak-free joints
• Retention of factory exhaust tips for a clean, OEM appearance
• Use of all factory hanger locations for hassle-free installation without modifications
• OE-style flanges and band clamps providing a complete 360-degree sealing surface
• 100% TIG-welded components ensuring durability and long-lasting performance
• Designed to retain factory valve motors for compatibility with stock exhaust valve operation

Construction & Design

The Mach Force XP Cat-Back Exhaust is crafted from premium 304 stainless steel tubing, mandrel-bent to maintain consistent diameter and smooth bends that minimize flow restrictions. The use of 3" tubing throughout the system allows for unrestricted exhaust gas movement, which contributes to improved engine efficiency and power delivery.

All welds are performed using MIG and TIG welding techniques, ensuring robust joints that resist cracking and leaks over time. The dual mufflers are engineered to balance sound attenuation with performance, absorbing unwanted high-frequency tones while delivering a deep, aggressive exhaust note characteristic of the Dodge Challenger’s muscle car heritage.

Performance & Sound

This exhaust system enhances performance by improving exhaust scavenging and reducing backpressure across the entire power band. The crossover balance tube plays a critical role by equalizing exhaust pulses between the two sides of the system, which not only boosts flow efficiency but also significantly reduces exhaust drone during cruising speeds.

The dual high-flow mufflers produce a powerful and aggressive sound that captures the essence of the Hellcat and 392 engines without becoming overly loud or intrusive. This balance makes the Mach Force XP ideal for both spirited driving and everyday use.

Installation & Fitment

The aFe Mach Force XP Cat-Back Exhaust is designed for a direct bolt-on installation using all factory mounting points. No cutting, welding, or modifications are required, making it a straightforward upgrade for Challenger owners. The system retains the factory exhaust tips and valve motors, preserving the vehicle’s original look and functionality.

Installation can typically be completed with basic hand tools and does not require specialized equipment, allowing enthusiasts to upgrade their exhaust system with minimal downtime.
