- How to Install MAC Boom Tube Axle-Back Exhaust on your 2005-2010 GT and GT500
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.

Old muscle sound
This exhaust system has been terrific, the sound reminds me of the 60-70's era muscle car sounds. Would recommend this to anyone who loves that type of roar.Helpful (0)

Good exhaust, it is not super loud but it does have a nice american muscle sound. Would pair this up with x pipes if you want really loud. Would’ve preferred a bet more kick to the sound but it’s still good.Helpful (0)
SLPLOUNDMOUTH OR FLOWMASTER OUTLAWS DID HE HAVE A BIG DIFFERENCE BETTEWN THE SLP LOUNDMOUTH AND THE OUTLAW. THE FLOWMASTER OUTLAW IS IT REALLY LESS LOUND THAN SLP LOUNDMOUTH I HAVE A GT 2005, AND I REALLY DONT KNOW WITCH ONE BUY. WHICH ONE IS GONNA BE THE BEST FOR SOUND AND PERFORMANCE. WITCH PART I COULD JOIN TO THE OUTLAW FOR INCREASE SOUND AND PERFORMANCE THANKS
Outlaw is plenty loud all by itself. If you want to amp it up try some long tube headers paired with an h pipe. But trust me they're good all by themselves
How do these sound on a V6 with true dual? Do you have a sound clip available?? I removed the X brand because of cabin drone... will these create a drone on the V6? Thanks
I have sound clips of a 2009 V6 with the ford racing dual exhaust that uses a true dual setup and the same mufflers as the bullett mustang, and the Flowmaster Outlaw. The Outlaw provides a much deeper throat tone to the exhaust making it more like a V8 sound. It has a little bit of drone at certain RPM's however it really gives the V6 a muscle car sound. The closest thing I can relate it to is the new Boss 302 Laguna Seca. IT SOUNDS AWESOME!!!!
Im looking for exhaust to fit a 2010 mustang that sounds like a Lamborghini, any ideas? This one sounded like it may have that same rumble/sound.
These would be two completely different motors and would no exhaust for a 2010 Mustang will sound like a Lamborghini.
im assuming you dont need a tune for this???
Axle-back exhausts generally will not require a tune.
Do the Flowmaster Outlaw series Axle-Back Exhaust add horse power to your Mustang.
That is a big yes and they sound real good and meaty.
The flowmaster outlaw will have a more aggressive and deeper exhaust tone.
This Flowmaster Outlaw Series Axle-Back Exhaust will not fit a 2005 Mustang GT500.
The Flowmaster Outlaw Series Axle-Back Exhaust will be legal in all states for inspection.
The Pypes Muffler-Delete Axle-Back Exhaust (05-10 GT, GT500), item # 20022, (http://www.americanmuscle.com/pypes-2005-gt-muffler-delete-axel-back.html) may have a slightly higher pitched sound than the Flowmaster Outlaw Series Axle-Back Exhaust, The Flowmaster's are going to have a very deep sound that is also loud. It also depends on what other exhaust mods you have made. Different headers and mid pipe will drastically change the sound of the car as well.
The flowmaster outlaws will offer a very aggressive exhaust tone that will be comparable to muffler deletes.
It would honestly depend on the x-pipe, but the Flowmaster Outlaws will generally offer a loud and aggressive exhaust tone.
This exhaust would help you get the back pressure you need while maintaining the loudness of your exhaust. While it won't be as loud as it currently is without mufflers it would keep the sound volume up there.
The flowmaster outlaw will be louder than the MBRP exhaust.
The Flowmaster Outlaw Axle-Back Exhaust will be close in loudness to the Corsa Extreme, but slightly louder. Tone wise both will be similar, and very raspy/racey.
The outlaws will have a crackle to them as well yes.
