      Review & Installation Video

      Hey, Justin here with AmericanMuscle.com, here with a quick break down and sound clip of Magnaflow’s muffler deleting axle back exhaust, fitting all 2005-2009 Mustang GTs, all 2007-2009 GT500’s.Ok let’s get the obvious out of the way, if you’re looking for a mild or quiet exhaust, you’ve come to the wrong place, the muffler deleting axle back from Magnaflow will give your 3 valve one of the most aggressive tones imaginable with the cats in place. Remove the cats, and the sound gets even crazier, of course any time you do that you’re running the risk of getting some rasp, but that’s to be expected any time you delete the cats and remove the mufflers. At first glance you can see that this exhaust is really nothing more than a fancy street pipe, all exiting out there brightly polished 3 ½” tips. I know that some of you may be thinking the price is a little on the high side considering such a simple design, but you have to factor in Magnaflow’s top notch quality and construction, in addition to the perfect fitment which do factor into the price. Speaking of the construction, Magnaflow went full stainless, from the 2.5” mandrel bent tubing, to those brightly polished 3 ½” tips I just mentioned. That stainless construction is going to save you a few pounds versus your factory axle back, in addition to looking good and resisting corrosion for years to come. This is a fairly easy install here considering you’re only replacing the Axle-back portion of your exhaust, with that said, just be sure to leave yourself about an hour to get everything bolted up. Now let’s hear how the Magnaflow muffler deleting axle back sounds compared to our factory exhaust.

        Very misleading ease of installation.

        Says exact match and stock exhaust. But when you go to put in the hangers only on the passenger side but I got to take it to a muffler shop and have the One support taken off and welded.

        Truly agressive

        Added these pipes along with air aid CAI and throttle body spacer and not only does it sound awesome but all together I would have to guess these add ons in conjunction probably added 20 to 25 horsepower . Now when I grab second gear she rips the tires loose

        Coming from magnaflow I was expecting a lot better. Welds are not good had two pices of wire inside the tubes I had to break off and get out. And the fit was way off had to modify my brackets. But SOUNDS GOOD and performs great.

        Great sound, bad fit

        First off I want to say these sound great. Just the way I wanted it to sound. But they just did not at all fit. I had to cut the hangars off and re weld them where I wanted them. From all the reviews I read. It sounded like they went right in. Not the case in my 2006/roush. But overall great product

        The design is clean, the crome makes the pipes stand out more. The sound is extremely load, makes heads turn everywhere you go. Money well spent.

        Magnaflow Race Series Muffler Delete axle-back

        Like most of you, I have looked and read and listened. Finally, I decided on the Magnaflow RACE muffler delete axle-back. My 2007 GT500 was very quiet and I wanted it to sound like it looked and ran. My biggest concern, when looking for new exhaust, was I'd end up buying something, not loud enough. The systems with mufflers...just didn't sound good enough to me. Once I heard the Magnaflows with no mufflers....that was it. I bought them from AM and they were here in no time. The pipes and tips are stainless...welds are perfect and they fit and line up easily. Not being able to see mufflers hanging under the car in back...makes it look alot better. You can spend alot of time, trying to get the old mufflers out, irregardless of what you've read or heard. Or you can cut the old muffler's hanger rods. It is not easy to get them out of the rubber and and out, if you don't. And if you pull the hangers instead, you better have some tools and time. l found....once the old mufflers are out...you will be able to install the new pipes, much easier, if you disconnect the mid-pipe, forward of the axle and drop those pipes a few inches, so you have some play, to get the new pipes hanger rods into the rubbers and line it all up. Then...just tighten the mid-pipes back up and you got it. It sounds perfect idling...and gets louder as you throttle it, as expected, but a good sound. At 70-80mph...the stock tires, are louder than the exhaust inside the car and I have no drone to speak of. It is the perfect way to get the sound you want, clean the rear of the car up...seeing no hanging mufflers any longer and gaining some felt, horsepower. Let it breath! Buy these and smile.

      I have a 2007 v6 with the pypes dual conversion exhaust, would this provide a louder sound on my v6? Or would the flow master outlaw be louder?

      • Both exhausts will be close to the same sound. We recommend listening to some exhaust clips to hear which one you like the best.
