      Review & Installation Video

      This axle-back is going to be a good option for you if you're looking for the most budget-friendly way to make the biggest change in your exhaust note with an axle-back. This is currently the most affordable axle-back on the site and it's a muffler delete setup, which means that this is going to give you the biggest change possible from an axle-back. The install for this is easy. It's a two out of three wrenches on the difficulty meter, but only because you do need to cut in order to install an axle-back on an S550, and you're looking at about two hours' time. This being a muffler delete system means exactly that. You're going to be completely eliminating your mufflers. So what you're going to get with this system is the pipes you see here with MBRP tips. That means that after the resonator mid-pipe, there'll be no more exhaust filtration. It's going to make for a very big change in every aspect of the exhaust sound. It's going to be much louder and deeper-sounding than the stock exhaust. There's a little bit of drone inside the cabin at cruising speeds. But honestly, I'm not surprised by that at all. The nature of a muffler delete lends itself to drone and it's not a terrible drone, but it is noticeable. With that being said, I'm going to call this one a five out of five on the loudness scale, one being a quiet upgrade, and five being a very loud upgrade. For an axle-back, you can't get much louder than this. I will say, though, that you should keep in mind that you get this volume and this sound with the stock resonator still in place. If you ever change your mid-pipe down the road, or even your headers, this system is going to get even louder and it has a potential to be very loud depending on what you do with the rest of your exhaust system. Just keep in mind the smaller diameter inlets that this axle-back has, being that it's made for the stock exhaust. The diameter of the axle-back is two and a half inches, so that it can bolt up to the factory exhaust without any issues. The tips are four-inch, polished stainless steel, and as far as materials for the rest of the axle-back, this is mandrel-bent, aluminized steel tubing. The fact that this is aluminized does help to keep the price so affordable. But you do have the downside of aluminized steel not holding up as well over time against harsher elements. This would be something that you should consider if you are shopping for a daily driver that sees all different types of road conditions. But if you're shopping for a car that only comes out during nice weather, this shouldn't completely scare you away from this product. When it comes to price, you can expect to pay very close to the $300 mark, which makes this currently the most affordable axle-back option for the S550. If you're looking for something close to this sound-wise, but you want stainless steel materials, SR Performance makes a muffler delete system for about $30 more that's stainless steel. You're going to be looking at the typical cut-and-clamp design with the install for this axle-back, since you need to cut all S550 axle-backs. I'm going to call this a two out of three wrenches on the scale, but just because of the cutting that's involved. It's nothing difficult, but I just recommend some eye protection and a fresh blade to make the cutting easier. Overall, you're looking at about two hours to get this all done. A lift would certainly make things easier for you here, but the job can be done on jack stands as well, if you don't have access to one. Cutting the factory axle-back isn't hard. Just be sure to measure twice, and plan a mark where you'll be cutting, so you don't make a mistake. Once you have the factory axle-back cut, you can drop the factory mufflers with the hangers. The new axle-back will come with new clamps for you. So you don't have to worry about transferring anything over, other than the factory hangers. Once you get the hangers over to the new axle-back, you're ready to install. You just flip the axle-back into place and bolt up the hangers. You can tighten the clamps on the axle-back. But it'd probably be easiest to leave the clamps on the tips loose until you have it all lined up, and then tighten them down. That's going to be it for the MBRP Pro Series muffler delete axle-back exhaust. But as always, you can check it out more online right here at americanmuscle.com.

        Trumpet with a rumble

        The Pro series axle-back was a great improvement to the sound of the stock exhaust. Of note: I used it with the stock H-pipe. It has an amazing sound throughout the rev range, starting at a deep rumble that raises to the classic mean V8 muscle car sound we've all grown to love. Seriously, the exhaust note get's a lot of love from other gearheads, and a lot of hate from boring people. The Pro series exhaust provides a great cold start and idle that will let your neighbors know you're around (if they're awake) but won't necessarily wake them up in the morning. Installing the mufflers probably took about 25lbs off the car in place of the heavy stock ones. All in all, if you want a great sounding car at a very good price point, you should get this kit.

        GREAT TONE !!

        Bought a new gt 5.0 and stock was too quiet . I had this installed (welded) for $105 and gave it a louder , deeper ,but still very daily driveable tone . I later paired it with the mbrp x pipe and boy she really screams now . It cost me another $130 for the x pipe install. All in all it sounds great ! If you’re trying to wake the entire neighborhood, pair this with the mbrp X pipe . If you want something that sounds good when you get on it , just stick with the axle back .

      How far back from the muffler should I cut the piping to ensure that the pipes align and end where they were intended?

      • You would just need to do some measuring and some math upon receiving this exhaust, relative to where and how you would like to tips to sit when all is said and done.

      Why would these not fit a V6?? Why aren't there any muffler delete setups for a V6?

      • This will not fit V6 models due to differing fitment when compared to GT models. We have a few muffler delete options for 15-17 V6 models here - https://www.americanmuscle.com/2015-mustang-axleback-exhaust.html.

      Would I still be able to pass a emission test if I remove the mufflers and add these to my gt?

      • Yes, emissions related tests have to do with your catalytic converters, since your mufflers are put downstream of these you should be good to go.
