    Hi I'm Justin with, and I'm checking out Magnaflow's Street Axleback exhaust system fitting the 2013 Mustang GT. I like to refer to this as the grown man's exhaust, and what I mean by that is, the Magnaflow street isn't going to be crazy loud or raspy, in fact it isn't all that much louder than your factory exhaust, what it does give you is a nice refined tone, with practically zero drone, that's mild enough while cruising around but still offers some good bark when you get on the pedal. The price of this axleback is a little high when compared to other 2013 axlebacks, but you get what you pay for, the Magnaflow is beautifully assembled and features 100% polished stainless steel throughout, including 3" mandrel bent tubing, and nice 4" polished tips featuring that Magnaflow logo. The install on this axleback is easy enough for just about anyone to tackle in about an hour's time using some basic hand tools. Now let's hear how the Magnaflow Street Axleback sounds compared to our factory exhaust.

    Save Money. Get the sound and sporty good looks that your 5.0-powered the 2013-2014 GT deserves without having to buy a complete catback system with the Magnaflow Street Axle-back system.

    Classic Muscle Car Sound. The Magnaflow Axle-back Exhaust 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.

    Magnaflow Quality.
    Constructed from 100% stainless steel for long life the Magnaflow Street axle-back 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.

    Made to be a direct bolt on, this Magnaflow axle-back will bolt right up without any extra modifications required on the the 2013-2014 GT Mustang for a deeper classic V8 sound.

        Drone? Hi I was wondering if these Drone at any RPM range or gear with 3.73's. I was also wondering how these are different than the 11-12 Magnaflow street axle-backs. Will the 11-12's just not fit my 13?

        • I have no insight to offer on the fitment, however, as far as drone I do. The only time I have ever run into a drone issue with magnaflow is when running any type of off road mid pipe. I've run several different setups over the years and always come back to magnaflow. A great product, awesome fit and in my opinion one of the best sounding systems on the market.

        Is this one a little more loud than the gt500 style axle-back exaust and does it pop more

        • Yes, this exhaust will offer a more aggressive exhaust tone.

        Are they louder then the GT500 Mufflers? Thx 4 your help

        • These will be a bit quieter than the GT500 mufflers as the GT500 natural sound is deeper than that of the natural GT model Mustang.

        what is the difference between the Magnaflow Street Axle-Back for a 2011 and 2014?

        • Since the 2011 and 2014 Mustangs will have different rear bumpers, the exhaust tips will sit at different heights. Magnaflow has adjusted the mufflers for this to make sure the exhaust tips will sit at the proper heights so they do not make contact with your rear bumper.

        whats the horse power if ive tunned the car and put a kn filter !

        • No idea. From my experience, tuning is usually slightly different for each car. I purchased these since I am adding a Whipple Blower to my car and needed to open up the exhaust.

            Magnaflow was right for me

            Had the Flow Master American Thunder on my 2014 GT, auto trans., and the drone was so bad that it rattled the knobs on the radio and my head, unbearable. I guess it would be OK for a very short putt around town, but to me all the noise was inside the car, not outside where it should be. Searched the You Tube videos and decided to try the MagnaFlow Street axle back, and what a difference. Louder than stock, a 3 out of 5 if stock is 1. The sound is that of new glass packs, not 10 year old, blow out glass packs, very mellow, deep, pleasant, and a good growl at half or more pedal, but no drone at highway. No pops on deceleration, no unwanted attention from the cops. However, upon cold start these are quite loud so I would back the car in the garage to muffle the sound to keep peace in the neighbor hood, in the am. Nice polished mufflers and tips...and the tips slash cut, double walled, not a rolled edge...beautiful logo, just very cool. Keep in mind that these are 409 stainless steel, and not 300 series stainless, and 409 will corrode over time if driven all year in salt, snow, rain (Chicago suburbs) but mine is a summer time car so that didn't matter. I buy after market exhaust for sound, and it's best to hear these in person first, then decide, as they aren't returnable if you don't like the sound. Would buy these again, and recommend, if a mellow glass pack sound is right for you. Since that time, I got an 2003 GT, 5 speed that has the Borla Stingers already on it (4 out of 5)...louder than the Magna Flow, no drone at highway speed, easy to squeeze the sound with the pedal, and just more fun. Yeah, I'm 68, I know I should be done with this stuff, but...

            Great looking stainless steel tips with a perfect rumble. No popping or cracking with these axle-backs. The volume is nice and low so they won't make the neighbors mad. Easy to install. They didn't come with clamps so I used the stock hardware. Good looking fit and finish!

            Love the exhaust sound

            The exhaust arrived in two days from time of order. The exhaust note is exactly what I wanted. I have a 14 GT premium convertible so I didn't want the exhaust to be too loud. Huge difference over the stock mufflers. The Magnaflows are about 1/2 the weight of the stock mufflers so the install was easy. The install took less than 1/2 hour. Save yourself some time and spray PB Blast on the stock hangers prior to taking the old mufflers off. Couldn't be happier with Magnaflow.

            Great with headers

            These axle-backs are great especially if you want to tame the sound of long tube headers like myself. I am running BBK long tubes with an offroad x-pipe and JPC over axle pipes with this axle back and could not be happier. It is only loud when I get on it. And also cold start it is somewhat loud but not crazy enough to call the police. There is no drone on the highway, there is a slight exhaust note though, not drone IMO but thought I should mention it.

            All I can tell ya is these exhaust pipes, they are The best. Makes my gee-t sound and act like a 70s Era muscle car. It has a distinct roar when you are just cruising. Just about everyone gives me a thumbs up. Best money I have ever spent! If these ever burn out I will be buying another set.

            No rapping, popping or cracking, just a nice deep tone. They are louder than factory mufflers and there is a slight drone at highway speeds. Finish is first class, especially the tips. Had to remove mounting brackets from frame to remove old mufflers which was a bit of a pain.

            Not too loud but not too quiet. Just right.

            I chose the street series axle back because I drive on interstate for an extended amount of time for my work commute. It doesn't drone and it isn't obnoxious. It has some growl on a cold start up but once warm it is only slightly louder than stock at idle. At wot you definitely can tell a difference in sound, it comes to life and it is perfect (for me at least). For those of you looking to delete your cats I'm sure these will still keep the exhaust at a manageable noise level. The street series looks great too, I like these tips a lot. It took About 25-30 mins to install them. I put it on a lift at work and it was pretty easy. Once I get another commuter vehicle and don't have to drive my mustang every day I'll add the boss style side exhaust h-pipe. Overall I love the magnaflow sound and am very pleased with their product. It is pricey but you get what you pay for.

            Magnaflow Street Axle-back Exhaust (13-14 GT)

            The mufflers are extremely high quality and fit was perfect. The Magnaflows installed in about 5 minutes per side once the OEM mufflers were removed and the clamp hardware removed from the OEM muffler (The OEM clamp is reused). It would seem that for the price, a new clamp should be added to the kit since the OEM clamp has a retaining strap that must be cut off and excess metal ground off to make it a clean job. Also, the Magnaflows are a little louder than expected, but do sound great - no offensive popping and little if any drone. The job took about an hour and a half -- the hardest part was getting the OEM mufflers off the car - they are much bigger (wider) and heavier than the Magnaflows. Overall, I would recommend them - but they are about 2x louder than the OEM mufflers on my stock 2014 GT 5.0.

            Deep, Low, and Sexy

            The video said this is the grown man's exhaust. 100% correct. Nice deep, low tone that is not overpowering, but comes on real nice when you get on it. Idle sound is low and clear, like she is ready and waiting. My neighbors appreciate that it's not real loud at idle and low speeds, one neighbor called the sound "sexy." Also very little drone inside the car. I have heard the Flowmaster American Thunder in person, and am really glad I went w Magnaflow.

            Magnaflow delivers again!

            After looking in to all the axle-back options and actually hearing one 'Stang with Roush axle-backs and another with Flowmasters both were too loud for my liking. I decided to go with the Magnaflows and I love them! Great sound but not too loud. Yes they are a little pricey but for me it was money well spent.

            I love the sound of these mufflers. A little pricey but worth every penny. These are smaller and lighter than the factory mufflers. I couldn't believe the weight difference. Everybody that has heard them so far like the sound better than the factor mufflers and said it is not too loud and sounds awesome.

            Scott was spot on in his video review of this product. I had no desire to be hated my by neighbors nor sound like that loud, higher pitched squeal that I hear from other cars. These did the trick. Definitely distinctive classic V8 sound that makes its mark when appropriate. Highly recommended.
