Description
Overview
The Flowmaster Outlaw Cat-back Exhaust System is built for drivers who want an aggressive sound level at all times, both inside and outside the vehicle. Engineered specifically for 2008-2014 Dodge Challenger SRT8 models equipped with the 6.1L or 6.4L Hemi engine, this complete cat-back kit transforms the exhaust note of your muscle car while delivering a clean, high-flow design from the cat back to the tips.
At the heart of the system is dual 3.00-inch mandrel-bent stainless steel tubing that feeds into Flowmaster’s exclusive Scavenger Series X-pipe. This layout creates a deep, unique tone while helping the Hemi make maximum power. From there, the tubing runs into a pair of race-proven Outlaw Series mufflers, giving the Challenger its signature muscular growl.
Key Benefits
This is a bolt-on upgrade designed with the home mechanic in mind. The tailpipes utilize the factory hanger locations for an easy installation, and the kit includes all necessary parts and hardware to get the job done. The system is finished with polished rectangular 304 stainless steel tips measuring 3.00 x 7.00, adding a bold visual statement that matches the aggressive lines of the Challenger.

Sound and Performance
The Outlaw Series is Flowmaster’s most aggressive muffler line, and this cat-back reflects that character. Combining the free-flowing dual tubing, the Scavenger Series X-pipe, and the Outlaw mufflers, the system produces a loud, deep exhaust note that announces the Hemi’s presence while supporting airflow for power gains. If you’re chasing an unmistakable, race-inspired tone, this system delivers.
Fitment and Installation
This kit is purpose-built for the 2008-2014 Challenger SRT8 platform in 2WD configuration. Because the tailpipes reuse the factory hanger locations, the install is straightforward enough to complete at home with the included hardware. Note that this system is CARB (California) compliant with Emission Code 5, and it does not include heat shields. A silver pipe finish and polished stainless tips round out the look.
Backed by Flowmaster’s Lifetime Limited Warranty, the Outlaw Cat-back Exhaust System is a durable, high-performance upgrade for Challenger SRT8 owners who refuse to blend in. This product carries a California Proposition 65 warning.
