The MACH Force-Xp cat-back exhaust system for the 2015-2017 Dodge Challenger SRT Hellcat is constructed from 3" mandrel bent 304 stainless steel and is MIG-welded. The system uses dual high flow mufflers with 3" tubing which improves performance across the power band while maintaining the true muscle car sound. aFe has incorporated a crossover balance tube to equalize and evenly distribute exhaust pulses traveling through the exhaust system. This not only creates a more efficient flow and better performance, the crossover balance tube also reduces sound decibels minimizing exhaust drone. aFe has designed this system to retain your factory exhaust tips. This exhaust uses all factory hanger locations for a hassle free installation. No modifications necessary. Leak-Free Seal: High quality OE style flange and band clamps are used for a complete 360 degree sealing surface. Aggressive Sound: Dual free-flowing mufflers are used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque. Crossover Balance Tube: The crossover balance tube equalizes and evenly distributes exhaust pulses traveling through the exhaust system. This not only creates more efficient flow and better performance, it also reduces sound decibels ultimately minimizing exhaust drone. Simple Installation: All systems use factory mounting locations providing stability and hassle-free installation.
