Borla ATAK Cat-Back Exhaust (15-21 6.4L HEMI w/ Active Exhaust)

Super Aggressive, Race-Optimized Exhaust Note. The Borla ATAK Cat-Back Exhaust utilizes ATAK (Acoustically-Tuned Applied Kinetics) technology to optimize racing sound. This is the finest, most aggressive exhaust upgrade for the 6.4L Challenger. This fierce, race-optimized note is sure to elevate your muscle car's presence as it sets the road on thunderous fire.

Maximum Performance. This Borla ATAK Exhaust efficiently maximizes the Challenger's engine performance. The straight-through muffler design enables the exhaust gases to efficiently exit the tubing, thereby creating significant increases in horsepower and torque. Furthermore, the mandrel bend facilitates smoother exhaust flow for optimum racing performance.

Supreme Durability. Borla manufactures its ATAK Cat-Back Exhaust using a high-grade T-304 stainless steel of superior strength. This material is specifically designed to withstand extreme temperatures from catalytic activities and resist the corrosive attacks of exhaust gases. Moreover, austenitic stainless steel meets the environmental and social requirements of releasing cleaner gas exhaust.

Straightforward Installation. This ATAK Exhaust features a direct bolt-on installation requiring moderate mechanical skills. Installation typically takes about 2 hours to complete. This upgrade installs to the Challenger's factory exhaust mounting locations with ease.

Active Exhaust Valves or Valve Simulators. This Borla Exhaust System is available with either replacement Active Exhaust Valves or Valve Simulators. The replacement Borla Active Exhaust Valves replace the OEM valves and plugs directly into the factory harness to operate just like stock. The Valve Simulator option does not include valves, so the exhaust is always open and at its loudest. The included "valve simulators" plug into the factory harness to trick the system to think the valves are still in place, therefore avoiding a check engine light.

Application. This Borla ATAK Cat-Back Exhaust fits 2015-2021 Dodge Challenger 6.4L models with Active Exhaust Valves. Please select your application from the options available.
