Excellent mellow sound, only loud when wanted

Nice rumble at idle and throaty sound when on the gas. Nice increase in sound and tone from stock exhaust but not excessively loud. Very slight drone at low highway speeds under 1800-2000rpms but no drone

Will these work with an off road x pipe? I have a BBK Off road X pipe and shorty headers set up, will these work with that?

  • Sure - the mid-pipe does not directly connect to the axle-back so you could use any axle-back you'd like that is designed for your year/model. Hope this helps!

What's the exhaust hanger kit option for? Hey AM, I wasjust wondering what the "exhaust hanger kit" option was for. I have never seen that and I would like to know, if I purchase these axle backs, will I require that for the install? I have a 2006 GT. Thanks!

  • The hanger kit is for cars that do not have rubber hangers from the factory, My 06 GT did have the rubber hangers and this installed perfectly with the existing hangers. Good idea to check though, since they did change the type of hangers in 06 (I think).

Will this require a tune? After installing these axle back exhaust, will I need (or can I benefit from) a tune?

  • Your Mustang will always respond to a custom tune, however because the mufflers are so near the end of the exhaust system, they are mainly to change the sound of the vehicle. There will be minimal HP gain and no real need for any change to the stock tune. It'll sound great though.

    Awesome product

    First off this axle back sys. was so easy to install !!! It took me about an hr. from start to finish and that included putting the rear end up on jack stands. All I needed was 2 ratchet wrenchs 1 13mm & 1 15mm fitment was perfect just had to play around with the rubber mounts a little to get both exhaust tips to hang level and centered in the bumper cutouts no big deal. As for how they sound they sound FANTASTIC not super loud but loud enough so that you can tell your exhaust is no longer stock and when you stomp on the gas they roar My Mustang now sounds like a muscle car but its not so loud as to make me think twice about taking it on a long road trip

    Nice rumble at idle and throaty sound when on the gas. Nice increase in sound and tone from stock exhaust but not excessively loud. Very slight drone at low highway speeds under 1800-2000rpms but no drone above that rpm. Very happy with the sound, installation, and quality.

    You wouldn't believe it !!

    I LOVE these axle backs!!! First of all, I took less than 24hrs for my delivery and I chose standard shipping (coming from PA to NY). As for the exhaust, it's exactly what I wanted!!! Has a low rumble at idle, then it kicks up with a little gas and then you KNOW flowmaster is responsible for that high-flowing-v8 and muscle car sound. Not obnoxiously loud, not pin-drop silence either, but almost like a magnaflow-pypes crossover. Throaty & only gets noisy when you want it!!!!

    fit and finish

    like most of you i listened to alot of exhaust sound clips when i came across a 2010 gt500 with the hushpower exhaust.for me it was the best i had heard so i bit the bullit and ordered them,the install was very easy about 40 min,the left side forward hanger had to be trimed a bit, the muffler body hit there and rattled when i hit a slight bump.just had to tweek them both so they lined up in the bumper cover pockets.the sound is amazing!! for all my fellow gt500 owners i recommend this axel back system..thanks a.m

    Nice toned muffler

    This is a great muffler if you don't like it too loud, but has a good throaty rumble. I had them installed at my local muffler shop.The mufflers had to be adjused for a better fit. They looked great. Got that factory look. I 'am pleased

    My 14 year old can install these

    Great product. The exact sound I was looking for. Thanks AM for having the different sound clips so I could get the exact sound. I had my 14 year old take the old mufflers off and install the new ones in about an hour and a half. Can't say enlighten about the sound. Just a great growl.

    Product is a great look with throaty sound.

    Pipes sounds amazing! Feels like I am driving a real muscle car! Install, only took a couple hours with assistance from a freind. Would recommend to others who are looking to upgrade from stock pipes.
