2005-2010 Mustang Flowmaster Outlaw Series Axle-Back (GT, GT500) Review
2005-2010 Mustang Flowmaster Outlaw Series Axle-Back (GT, GT500) Review


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.

    Flows are raspy, but once you let the car run for a good minute, the popping goes away…

  8. natesslowfox says:

    These are like SLP loud mouths….with no fiberglass or anything, They sound amazing, but you would probably want to keep your cats to keep the noise down lol

  15. Juan M says:

    are these axle backs just for sound or do they actually give u a couple HP?

  16. Addy Muñoz says:

    I got my Outlaw Axleback Series installed yesterday, took them just 30 minutes to install them, I have a 2008 Mustang GT but mine doesn't have the crackle sound like this one. Sounds the same tho and I love it!

  17. ThatRed3V says:

    Your shirt man…the right sleeve…just fix the end there.

  18. Sam Fisher says:

    if I upgrade from single stock exhaust to this duel exhaust will I need a new bumper?

  19. aeroman568 says:

    Put this on with longtubes and a catless h pipe. Would do a sound video but my phone doesn't pick up a cold start it is insanely loud.

    I know what axleback I'd get if I get an 05-09 GT.
