Hello. Will the GT500 mufflers fit a car that has a flowmaster hushpower exhaust already installed? Currently I have a Flowmaster Hushpower cat-back exhaust installed. I would like to switch mufflers to the GT500 mufflers. The Hushpower mufflers have a little too much drone for me. Will the GT500 mufflers fit or will I have to switch back to the stock pipes?

Lipt03 Year: 2011 Model: GT

  • If the over axle pipes have a different style of fitting then stock or a different angle then then stock, you will have to change back to the stock cat back. The fitting type of this axle back is a ball and socket type, I'm not sure of the Flowmaster fitting type but if it's a slip on style it won't work. The GT500 mufflers are the exact same fittment as the stock mufflers, after all they are stock on a GT500. Hope that helps you out!

Which exhaust to go with? Hello, I was wondering which would be more beneficial, a catback exhaust or this axle back and an X pipe? I am trying to decide which direction to go in since the cost would be reasonably similar. Thanks.

  • Stick with the axle back...more than sufficient for sound quality and air flow. The GTs already have decent flowing cats and mid pipe exhaust, better than the V6s. Swapping out all the other exhaust pieces will get you a voided exhaust warantee and probably a failed emissions (if applicable in your area). The cost between the 2 options isnt even close.

    Great sound, great price.

    I was looking for something with a slightly more agressive with a deep, almost subvocal "thrum", but without roar or drone. After countless sound samples and YouTube videos, I decided that this one sounded the best for what I wanted. The big surprise was the price, which was very reasonable. Installation was relatively easy, and the bolt-on clamps made fitment and adjustment a breeze. The only issue was that it came packaged in a Ford Racing box, and the tips are NOT padded enough for the way UPS treats a box. The weight of the mufflers caused the tips to punch through the styrofoam padding and hit the cement of my porch upon delivery, bending it and scuffing it. Luckily, the tips are not super-buffed or double-walled, so I was able to hammer it out with a mallet and a wood dowel, though there's still a bit of a scuff. The tips themselves are pretty no-nonsense. Nevertheless, I'm very happy with this muffler. Car is a 2012 Mustang GT with the stock H pipe.

    Sounds great, but still reasonable volume

    I wanted a better sound from my Mustang but did not want to go around attracting cops or irritating the neighbors. I'm happy to report the GT500 axle back is exactly what I was looking for. They totally change the sound of the car and are as quiet as stock on the highway. There is a little bit more volume under acceleration (sounds great) but not enough to worry about noise ordinances or nasty notes from your neighbors.

    Not Too Loud, Not Too Quiet, Just Right

    This exaust has a great note that is pleasing to the ear but doesn't cause your fillings to fall out. The stock system was too muted but this adds just the right amount of exaust note to get the adrelaline going. And there is no drone what so ever like most aftermarket systems. I chose not to install it and the installer was suprised by the pleasant sound and said he never put on another system that did not drone on set RPM's. If you buy this exaust you won't be disappointed.

    This should be the stock GT exhaust!

    Love this exhaust. As soon as you turn the key after you install it, you will be pleased. Not super loud, no drone, just a nice improvement from stock.

    It took me 6 months to pick out exhaust for my 2002 GT. I'm a very picky individual. Wanted a good mix of volume and tone without highway drone and too much rasp. I researched the forums and YouTube for the perfect exhaust and kept going back to the GT500 Axle Back. Its got the volume and its got the tone. Its a great base exhaust, and as you add on the x-pipe or headers it seems to only get better unlike some of the other kits out there. Install was pretty straight forward, however I found a better how-to using google than what is supplied here. The how-to uploaded here is for Flowmasters which are shorter mufflers and will allow you to reach the hanger bolts to remove the hangers entirely. The GT500s will cover those bolts up when hung making it impossible to reinstall the bolts if you took them off after removing the stock exhaust. TIPS: -Loosen the panhard bar and drop it via removal of the two driver side bolts before you start. This will allow for easy removal and installation. -Jack up the vehicle as high as you can -Have an extra set of hands with you -Wear safety glasses -Don't tighten up the clamps until you align the tips.

    GT500 axle backs.

    These sound great and look much better than the stock exhaust. Not to loud while cruising but loud enough when you step on the gas. They have a nice rumble at idle. Easy install, took about an hour.

    Great sounding axleback at a more than reasonable price.

    This is a great sounding axleback that will not break the bank. As others have mentioned, this is the sound I expected from the factory. Larger tips fill up the rear valence much better than the stock muffler. At cruising rpms, I would say this is just as quiet as the OEM muffer but when you get on it, you know it is there. This is also a straight forward install that can easily be done in an hour taking your time.

    The Lion Sleeps Tonight

    Once in a while a part comes along that makes you want to slow down and take it easy - live a little in the 7 – 10 o’clock side of the tach. For me at least, that part has a name: M-5230-MGTCA1. Most people refer to these as the “GT500” axle backs. I’ve spent about a month with the 2014 Mustang GT [Track Pack] and have become very familiar with almost every aspect of it. This car has proven to be the result of a heroic effort on Ford’s part, finally striking that ideal balance between performance, fit & finish, and price. Where before, cheap materials and other obvious cost-cutting would abound, the driver is surrounded by a slew of more touch-friendly and appealing textures and materials. Add to that the suspension and power train – what is this world coming to?? Where was this car a few years ago? I could’ve said with certainty that the world was coming to an end – the Saints have won the Super Bowl, I now eat raw fish and love it, and a Mustang can handle! Surely there’s a Hades freezing over somewhere! You can see the pattern here – Ford has given us a great platform upon which we can tweak and modify until we find that personalized, magical combination of ingredients. We’ve got an über-rigid chassis for suspension tweaking; a relatively powerful brake master cylinder for brake upgrades; a smooth and powerful motor with strong internals to handle power adders, and yadda/blah/etc. My coffee hasn’t gotten to work yet and I’m getting off track. One of the points I wanted to address was the exhaust tone. Like the rest of the car, it’s really decent as-is; it has a deep and mellow tone, which allows bystanders to connect the dots, so to speak. When you have your cold start moment, or you are running through a parking garage, or simply rowing through the gears down the road, people assume you’re playing with a V8. The [delightfully/sexually tuned] induction system on the Coyote does most of the talking while the mufflers are out back muffling or doing whatever it is they do – who really knows? With all that seductive rumbling happening up front, it’s easy to forget about the action out back in the Mullet Zone; weren’t we told there’s a party out back? Well, get yourself some axle backs, son! My criterion was simple and only had to meet a few non-negotiables: It had to be at least twice as loud as stock and ten times as mean; it can’t be obnoxious – I wanted it “out of the way” when I was at a stop light or idling somewhere; and it can’t drone – I enjoy the happy space inside of the Mustang. After getting this in line I set about the YouTube for answers. And then 5 minutes later, I realized that all of the clips sucked and I’d end up having to gamble. So, I did. The smartest thing you can do when installing the driver’s side muffler is to cut off some hanger material – there’s too much there and if you just remove about half of it, you can slide it onto the rubber mounts without having to remove the bracket. The driver’s side took about 15 minutes, while the passenger used up 10 in total. At startup, I instantly knew I made the right decision. The 5 liter announced its presence with authority and sent chills up (and down) my spine. I’ve seen decibel meters comparing the sound output across several popular axle backs, and among them the GT500s rank in the bottom percentage. Do not let that fool you – the perceived volume is what counts (unless your car is loud enough to have Poncharelli waving the meter near your tail pipes). The reality is that these mufflers are twice as loud as the stock mufflers – for me, this is perfect. Let’s talk about the tone. When you are driving your GT – when you are driving a V8, you want it to sound…angry. That’s because it is. You’ve got an extra 4 cylinders that were called in to work for nothing. An inline 4 could’ve done the job of propelling the car. With the stock exhaust, question marks hung above the heads of those around you. In fact, no one even bothered to think about your car until they actually saw it and the experiences were limited to, “Oh, look…another Mustang”. Now, when you are anywhere on the tachometer off idle, there is no mistaking what’s happening under the hood. Now you are in the Mullet Zone and everyone knows it – the Business up front KNOWS there’s a party out back. The exhaust tone is of the gods and it is the sound you hear in your mind when you think of muscle cars. It’s as close to the pushrod sound of the 5 liters of yore that you’re going to hear, where the mid-mounted mufflers and long tail pipes created a distinctive and aggressive throaty roar. You could hear that tone and identify it as a Mustang long before you saw it’s boxy Escort-esque form hauling buns down the street. If that metaphor doesn’t paint the picture for you, imagine the sound of a roaring lion – deep, thunderous, and chest bass mix in with throaty, guttural midrange coalescing into a breathing and heaving presence. As the RPMs decrease mid-shift and coming off throttle, it is as though the coffee pot of Zeus himself has fallen from the heavens, fusing its essence with the GT; the exhaust crackles, snaps, pops, and percolates, serving up the most intoxicating brew of the gods. Like me, you will find yourself wanting to sit around in slow moving traffic with windows down playing in the left side of the tach. Parking lots will give way to turning heads, rock fists, and thumbs up from the guys. Women’s faces will contort either in disgust or eros. Babies will cry and young boys, clinging to their parents as baby apes on the backs of their mothers, will solemnly gaze as the roar of your car burns into their hearts the desire of achieving this sound. Suddenly the balance of your car becomes less about speed and more about feel. You will think about this sound long after you put your car to sleep for the night, waiting for the chance to climb back in for anther pull of the god’s brew.
