For the enthusiast who wants to be heard, Flowmaster [1] introduces the Outlaw Axle-back exhaust system for popular late-model muscle car applications. This Outlaw Axle-back system is the most aggressive sounding system to date, even louder than the American Thunder series. Featuring Flowmaster’s race-proven Outlaw mufflers, this bolt-on system gives a deep aggressive exterior sound with an aggressive interior tone as well. The Outlaw mufflers are finished with polished T304 stainless steel and embossed 4-inch diameter tips. They are all manufactured in the USA from 16-gauge 409S stainless steel, this exhaust system comes complete with detailed step-by-step installation instructions and Flowmaster’s limited lifetime warranty.

In addition to Flowmaster’s new stainless Outlaw kits, they have also stepped up and converted their entire line of late-model muscle car exhaust over the 409S stainless steel. This includes the moderate tone of the Hushpower Pro Series muffler, which delivers dyno tested horsepower and torque improvements across the board. Outside of mufflers most cat-backs sport a full 3-inch, mandrel bent stainless steel construction with a Scavenger X-pipe assembly for mid-range torque improvement and a pair of Hushpower Pro Series mufflers, or the alternative sound of the Flowmaster chambered design like that of the American Thunder.
