Description
Overview
The Flowmaster Outlaw Cat-back Exhaust System is engineered for drivers who want their Mopar to bark. Purpose-built for the 2015-2023 Dodge Challenger SRT 392 and R/T Scat Pack with the 6.4L engine, the SRT Hellcat with the 6.2L engine, and the 2017-2021 R/T with the 5.7L engine, this complete cat-back setup transforms both the sound and the presence of your car. It’s the ideal choice for anyone chasing a very aggressive exterior tone when hard on the gas while keeping a more moderate note when cruising.
At the heart of the system is a pair of race-proven Outlaw Series mufflers finished in black, each measuring 19.50 inches in overall length with a 3.00-inch outlet. Dual 3.00-inch mandrel-bent stainless steel tubing feeds into Flowmaster’s exclusive Scavenger Series X-pipe, delivering a deep, unique sound while helping the engine make maximum power. The result is an unmistakable muscle-car soundtrack backed by proven flow.
Active Valve Ready & Muscular Looks
The tailpipes incorporate high-quality active exhaust valves that are ready to reuse your factory actuators, so you retain the OEM adjustable exhaust experience without extra components. Note that the valve actuators are not included — you’ll reuse your OEM units. The whole system is capped off with quad 3.50-inch 304 stainless steel embossed tips, giving the rear of the Challenger a bold, aggressive stance to match its voice.
