      Video Review & Installation

      Hey everyone I’m Justin with AmericanMuscle.com, and today we’re going to be breaking down the Outlaw series Axle-back from Flowmaster for the 2005-2010 Mustang GT. Flowmaster calls this their most aggressive Axle-back system available for the late model 46 Mustangs. This entire kit centers around these two outlaw series mufflers, which to the casual observer, hardly resemble mufflers at all, but rather highly engineered resonant tubes, which are responsible for that super aggressive tone. Like many other Flowmaster kits the Outlaw series features 409 grade steel construction and 2.5” mandrel bent tubing. It also features this very sleek black finish, which is going to be great at resisting corrosion. Everything exits out of these dual 4” polished tips, embossed with that classic Flowmaster logo. Installation of this Axle-back is very straight forward and should only take you about an hour using some basic hand tools. Now let’s hear how the Outlaw series from Flowmaster sounds compared to your factory exhaust.
