Review & Install Video

Hey, Justin here with, 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.

Loud Aggressive Sound. This Magnaflow Race Series Axle-Back will give you the loudest most aggressive sound possible without having to replace your entire catback system. This Magnaflow Axle-Back features a unique muffler delete design that replaces your stock wimpy-sounding mufflers for a much louder and more aggressive tone.

Quality Magnaflow Construction. The Magnaflow Race Series Axle-Back system is constructed from mandrel bent 2.5" stainless steel tubing for long life and a perfect fit. The system features a muffler delete design that ends with brightly polished 3.5" stainless tips, that exit in the stock location for impressive good looks.

Application. Made to be a direct bolt on, this Magnaflow Race Series Axle-Back will bolt right up with no modifications required to fit the 2005 to 2009 GT, Bullitt and Shelby GT500 Mustangs for the deepest aggressive sound possible.

Technical Note: Americanmuscle recommends adding the 2005+ Mustang 304 Stainless Steel Exhaust Hanger Kit from the drop down option above, to provide more strength, stability and a cleaner installed appearance. If you have a 2007 Mustang you may need the kit for correct installation.

    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

    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 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.

    Magnaflow Axle back (muffler delete)

    Although not the best bargain for the money considering the available choices, the product makes up for it with its quality construction / fit and finish. The install on my 2007 Shelby GT 500 took me 2 hours, which included the removal of the replaced pipes. As for the sound, its awesome. The car now sounds like a beast. Acceleration above 2000 RPM really wakes up the exhaust sound. However, at cruising speed, the exhaust remains reasonably quiet considering the lack of mufflers.

    Fit was great

    The first pipe took about twenty minutes. The second took ten. The tabs on the mid pipe fit in the notches on the tail pipe. Can't make a mistake.

    It's louder than I thought even if I had listen the sound. You should accelerate more in the video to hear the real sound.

    Magnaflow Muffler-Deletes

    Took me about an hour to install them. When I first heard the thunder, I was excited as a baby about to be breast-fed. Other cars will be intimidated by it, and you'll be the jerk of the neighborhood, and there is a tiny boost of power to go with them. They are the loudest for 05-09 Stangs. Thank you AM.
