Installed relatively easily, took longer to get the OEM exhaust out than to install the new exhaust. Sounds great, about a 20lb weight drop, perfect.Helpful (0)

Great sound and look
The stock exhaust on the GT500 is great honestly, but this is how it should have sounded from the factory. The car sounds and feels so much different. When cruising there is no discernible drone but they are extremely loud when you want them to be. Louder than I expected, but not louder than I like. The tips are more staggered than the stock exhaust tips, so expect them to poke out the back end a little bit. Spend a little extra time adjusting them to your liking if you install them yourself (or have a friend do it for you). The tips really fill out the rear valance so be sure to check them after driving with them a bit and readjust in case they wind up resting against the bumper so you don't melt it. Took about an hour and a half without a lift and a couple of beer breaks. I had some buyers remorse initially after spending $727 on axle-backs but I do not regret this purchase at all. Received them 2 days after ordering, and the box was huge. Packaging was excellent.Helpful (0)

I was researching aftermarket exhaust for a while and was hesitant to change from my OEM setup on my 2013 GT500. I’m so glad I got these. They are perfect! Just the sound I was looking for. They have a nice deep rumble when driving and plenty of back-rap on deceleration. They aren’t obnoxiously loud, but definitely turn heads on the street. Black exhaust tips look great too!Helpful (4)

Loud but fun
Pieces came VERY well packed, no cosmetic blemishes whatsoever. They are much lighter than stock--by a good 20lbs or more per side. Installation was without issue once I figured it out; first side took much longer than second. One side fit right out of the box, other side needed some slightly adjustment to the rearmost hanger before it wouldn't sit up against the ABS rear valence, but nothing major. They retain the heavy H-pipe rumble with the rest of the stock exhaust system, but will literally ring your ears if you punch it with any surface next to you with the windows down. Standing behind the car while it was being dynoed shook the concrete foundation of the building and fluttered any loosing clothing, it is seriously loud, even with the rest of the exhaust stock. It would be almost ludicrous with an off-road X-pipe. The tone under low load is almost like a double-volume stock exhaust, but under medium or higher load it brings in a very loud resonance that the stock mufflers completely dampened. It sounds like a straight-piped race vehicle, even with cats and stock exhaust otherwise in place. Some people may find it too much, and I won't blame them, but you won't get into that sound while driving normally. It only shows up when you give it a good amount of load, when you want the car to really open up anyways. Highway drone in 5th is definitely there, but pushing up to 6th completely negates it. I can hear the rear drive gears more than the exhaust cruising at 75mph. Supercharger whine gets overpowered by the exhaust volume, however, unless you're above 5,000rpm, at which point you can hear it if you try (stock pulley). I don't think some simple finished pipes are worth near to $700, but it's the best you're going to find. With that being said, the welds and finish are all amazing, and the tips are three dimensional and not just simply rounded flat sheet metal. Overall, worth the buy, compared to other options. Set aside more time than you'd think if you're pulling the stock mufflers for the first time, since they require quite a bit of finagling.Helpful (6)

These tips will wake the Dead LOL!!!
I have had these on my 14 GT 500 for over 2 years now best sound ever. It is not my daily driver so I wanted the big block 60's muscle car sound got it and then some!!!!! I had herd the other magnaflow option for this car (MagnaFlow 3" Street Series Axle-Back) as they only offer 2 systems for axle back and was not impressed. It was almost identical to the factory sound and almost $1,000. As there are not many of these GT 500 cars it is really difficult to get an IN Person look and listen"..... Going on you tube also did my ears no justice. So these comp axle back tips that I got my buddy 2 blocks away says it sounds like a 427 dual quad 67 Corvette with side pipes. These pipes have an extremely deep rumble when you hit the throttle. When you are just cruising they have a nice tone to them. When you put the pedal to the floor be ware who is around "cops" in particular. It is extremely loud meaning a deep resonating tone that can be herd quite a ways away. I can not tell you power was also increased if you can imagine on the vehicle which alreday has so much to start. Installation was easy 45 minutes on my back in the garage no lift needed. If you want to be loud and proud get these no regrets. If you live in a area where you can set off car alarms you will. Hope this info is helpful. Cheers, MarkHelpful (7)

Nice but wrong connectors,
The sound of the exhaust is amazing, super load growl, and spits like crazy, some people don't like that kind, but I love it, only big problem is that this exhaust set up doesn't fit a Magna flow exhaust pipe tube, it only fits the stock exhaust pipe set up, so there was some cutting and fitting issues to fit to an existing magna flow exhaust tube, but once installed, get some ear muffs, its LOUD,Helpful (3)

Not loud enough !
They sound ok, but not loud enough for me..So i'm going to be buying a new louder Axle-Back Exhaust to replace this soon.Helpful (3)
Would installing this kit effectively delete the factory resonators? I am confused as to where they are located but I have found lots of people saying their Shelby sounds much better without them.
This axle back kit would replace the OEM resonators yes.
Will this axleback fit the Borla ATAK mid pipes I have on the car?
Unfortunately, due to the size difference between this kit and the Borla ATAK pipes, these would not be compatible unless modified.
Is it possible for these to fit a 2014 gt?
Unfortunately I cannot guarantee fitment on a 14 GT as this axle-back exhaust is designed for 13-14 GT500 models.
Would these tips fit on a 2014 v6 mustang with BBK off road X-Pipe with long tube headers? And of course I would cutt the bumper to make the GT500 rear valance fit??
The Magnaflow Competition Axle-Back Exhaust is made to fit the 13-14 GT500. We can not guarantee fitment on other models.

Unfortunately the Magnaflow Competition Axle-Back Exhaust will not fit a 14 V6 model as they are designed to fit a 13-14 GT500 and will not fit any other model.
Hello, The Magnaflow Competition Axle-Back Exhaust w/ Black Quad Tips are intended for 2013-2014 models. With some custom work you could make them fit on your 2012 GT, yes, but they are intended for the 2013 and 2014 model years.
Since the 2012 GT came with the dual exhaust system instead of the quad-exhaust, this will not fit a 2012 GT without custom modification.
Unfortunately this is only offered in black and for the GT500 model Mustangs from 2013-2014.
Even if your car was equipped with a GT500 rear valance, this piece would not fit properly on a V6 as the size of the piping and the length of the exhaust will be too large.
Hi, We only carry this Axle-Back with black tips, these are guaranteed to fit on 2013-2014 Shelby GT500 Mustangs and these use the factory hangers.
The Magnaflow Competition Axle-Back Exhaust would have drone to it, as it is designed for competition use, and not the average street going Mustang.
The Magnaflow Competition Axle-Back Exhaust w/ Black Quad Tips has slanted tips; somewhat like the factory exhaust tips.
We do not have any sound clips of the Magnaflow Competition Axle-Back Exhaust w/ Black Quad Tips (13-14 GT500). We would recommend going to local car shows of checking online for some exhaust videos.
The Magnaflow Competition Axle-Back Exhaust w/ Black Quad Tips (13-14 GT500) should have no issues with emissions testing. However you will need to contact your local authorities to check as each state is different.
If you have questions about restrictions or accepted modifications you can make to your Mustang, including the Magnaflow Competition Axle-Back Exhaust w/ Black Quad Tips (13-14 GT500) please call your local authorities for further information.
