The aFe SS Axle-Back Exhaust for the Dodge Challenger and Charger Hellcat (2015-2023) is a high-performance exhaust system designed to enhance vehicle output. Constructed from mandrel-bent stainless steel, this system maximizes exhaust flow, resulting in increased horsepower and torque. It also improves overall performance by lowering exhaust gas temperatures, which can contribute to better engine efficiency. Each system is dyno-tested and flow bench verified to ensure optimal gains. Features include welded hangers with swaged ends for durability, slotted and swedged ends for secure fitment, and premium quality materials that ensure long-lasting performance. This axle-back exhaust provides a deep, aggressive sound while maintaining reliability and efficiency.

Designed specifically for 2015-2023 Dodge Challenger and Charger Hellcat models, this system is a direct bolt-on upgrade that replaces the factory exhaust components. It is suitable for enthusiasts seeking improved performance, sound, and exhaust flow, whether for street or track use. The kit includes all necessary components for installation, ensuring a straightforward upgrade process. Compatible with vehicles equipped with the stock or aftermarket exhaust configurations, this system is ideal for those looking to maximize their vehicle’s power output and sound profile. It is engineered to fit seamlessly and deliver consistent, high-quality performance.

Overview

  • Increases horsepower and torque
  • Improves performance
  • Lowers exhaust gas temperature
  • Flow bench and dyno tested
  • Welded hangers with swaged ends
  • Slotted and swedged ends
  • Premium quality band clamps
  • Backed by a 2-year limited warranty
  • Proudly made in the USA

A performance exhaust system is one of the most common ways of improving a vehicle's operation. The theory is simple; just reduce restriction to increase exhaust flow and you gain power. But all exhaust systems are not created equal; in reality there's more to it than just selling some sewer pipe sized tubes.

aFe tests its systems on the flow bench and the dynamometer to determine the right pipe size and muffler construction. Then they mandrel bend the pipes to ensure they maintain their shape and size throughout the entire length, to provide smooth, unrestricted airflow. Tubes that are not mandrel bent can lose up to 20% of their diameter in sharp bends. Some systems also include a straight muffler delete pipe if a more aggressive sound and maximum flow is desired. A typical aFe system will increase exhaust flow by up to 29% and lower EGT (Exhaust Gas Temperature) by up to 100º, with a corresponding improvement in power and performance.

But performance is only part of the equation. A quality exhaust system should be easy to install and made to last. The muffler and all pipes of the Mach Force XP system are constructed from durable 409 stainless steel. To ensure a tight seal, slotted and swedged ends are used whenever possible. When used with the supplied premium quality band clamps, the tightest, leak-free seal is the result. Every hanger is thoroughly welded
