Review & Installation Video

Hey everyone I’m Justin with AmericanMuscle.com and I’m checking out MAGNAFLOW’s street series axle-back for your 2011 or newer Mustang GT. The street series lives up to its name by offering a very streetable exhaust tone. It’s mellow enough to drive around town, but provides plenty of bark when you hit that loud pedal. The exhaust is constructed from 100% stainless steel and features mandrel bent 3 inch tubing, all exiting out these dual polished 4 inch tips. Install is a breeze and should take you no more than an hour using standard hand tools. Now let’s hear how MAGNAFLOW’s street series sounds in comparison to your factory exhaust.

Save Money. Get the sound and sporty good looks that your 5.0-powered 2011-2012 GT or supercharged 2011-2012 5.4-powered GT500 deserves without having to buy a complete catback system with the Magnaflow Street Axle-Back system.

Classic Musclecar Sound. The Magnaflow Cat-Back Exhaust System includes a set of two Street Series Mufflers that feature a free-flowing, straight-through perforated stainless steel core, with stainless mesh wrap and acoustical fiber fill to deliver that smooth, deep muscle car tone.

Quality Construction. Constructed from 100% stainless steel for long life the Magnaflow Street axleback exhaust system features two Street Series mufflers with polished 4" stainless steel tips. The 3" tubing is mandrel bent to improve exhaust flow and to assure a perfect fit.

Application. Made to be a direct bolt on, this axleback will bolt right up without any extra modifications required on the new 2011-2012 Mustang GT or 2011-2012 GT500 for a deeper classic V8 sound.

It was a little hard getting off the old mufflers, but once they were off the new ones popped on in no time. The magnaflows are perfect for what I was looking for. They aren't ridiculously loud and they ...

    Mean Sounding Exhaust!!!

    It was a little hard getting off the old mufflers, but once they were off the new ones popped on in no time. The magnaflows are perfect for what I was looking for. They aren't ridiculously loud and they definetly aren't quiet. Just cruising around my car sounds a lot meaner now. The tone is much deeper then the stock ones and it sounds great. No drone what-so-ever! The 4" inch tips look a lot better as well. The only complaint I have is that when they came they had been sprayed with packing foam and most of it ended up going up to tip into the muffler, other than that i have no complaint with AM. Came in the mail very fast! Overall perfect for what I was looking for.

    Magnaflow

    Awesome sound at idle, not obnoxiously loud. Inside car sound little more than stock if any.........definitely know the difference when you get on it. Outstanding quality, worth the difference in price to cheaper alternatives. No drone.

    Magnaflow Street on a 2012 GT500

    First off, the build quality is exceptional and the fitment is perfect. I was hoping for a muffler that retained the stock tone with a little more sound. These mufflers are slightly quieter than stock except at high RPM's. They produce a more bass-ey and monotone sound, which, personally, I don't care for. If you're looking for something that is quiet and produces more power, these are great. I have a 2.8L Kenne Bell and these mufflers made 17whp and 11wTQ over the stock ones. If you're looking for something that retains the nice growl and full spectrum sound, may want to look at another option.

    Awesome Mod

    Just put these on my 2012 GT and everything went smooth as silk! Easy to install and the tone is exactly what I was hoping to get. Could be just a touch louder, but all in all, an awesome mod!

    Awesome Magnaflow

    I had a professional shop install this kit for me. This is just "Amazing" in sound. It's not any louder than the stock mufflers. It's a deeper tone and has more "growl" when ON the gas. It was a close tie to getting the flowmaster kit. I am a previous Magnaflow customer and I just love their products. ** Interior noise is NOT elevated at all ** for those of you who's wife's don't like that noise inside the cabin. This kit was 100% perfect for me. Loving it very much!!

    Awesome sound at idle, not anoyingly loud at any rpm. Sounds best under acceleration, slight drone at certain rpm, excellent build quality. Easy install but you really need two people. I would buy them again in a minute.
