21C F150 2.7/3.5/5.0L FLOWFX CATBACK EXHAUST SYS DUAL 3IN TUBING 409SS

Introducing Flowmaster’s loudest and most extreme exhaust system to date: the Outlaw. Engineered for the street and strip, Flowmaster’s Outlaw-series exhaust systems include race-style mufflers, minimal restrictions, and raucous sound. Outlaw exhaust systems are engineered to last, featuring heavy-duty stainless steel piping for long-lasting service, even in parts of the country that regularly experience heavy snowfall and salted roads. Even outlaw mufflers feature MIG-welded stainless steel construction, preventing the corrosion and holes associated with conventional aluminized steel. Flowmaster Outlaw Exhaust Systems don’t only feature an aggressive exhaust tone and next-level durability, but also enhanced performance! Mandrel-bent piping and high-flow mufflers reduce exhaust restriction, producing dyno-proven power gains throughout the RPM band.
