      Review & Installation Video

      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.

        Very low and deep tone, but pitch doesn’t really change much with rpm.

        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...

        Magnaflow, the grown mans exhaust

        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!

        Deep and Throaty

        These axle backs were easy to install. They sound and look fantastic. They are not much louder than factory, which is what I wanted. I did have to cut the factory clamps off and reuse them, but it took all of five minutes.

        Just got them installed. They sounded better than I anticipated. Just the right amount of volume, and makes the car sound the way it should. Fit and finish are superb. Magnaflow is the best.

        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.

      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.
