Review & Install Video
Hey, guys, Stephanie with americanmuscle.com here with a review and an install of the Mishimoto Race Axle-Back Exhaust that's available for the 2015 and up S550 GT Mustang. We're gonna cover a few things with this exhaust in this video. We'll mainly be talking about the sound of the axle-back, the materials, and the install. The install process is easy, it's a two out of three wrenches in the difficulty meter, but only because you do need to cut in order to install an Axle-Back on an S550, but we'll talk more about that later.
The Mishimoto Race Axle-Back Exhaust is going to be a system that you should check out if you're looking to make a big change in your exhaust note while spending minimal dollars and still going with the setup to give you good materials and manufacturing. This axle-back is a muffler delete rate system, and muffler delete axle-backs are more budget friendly than normal muffler assemblies. So in this case, you're getting a ton of sound with a small change, and you aren't totally killing the bank account.
Normally, in an axle-back video, I would start by talking about the mufflers right about now. In this case, we don't have any mufflers. Mishimoto made this muffler delete system in order to deliver on an aggressive note that's loud and that reduces the normal flow restriction that you get with the traditional muffler setup. All that you're looking at here is stainless steel tubing, that pulls up to the factory piping or Mishimoto X / H mid-pipe, or another after-market mid-pipe that ends with four-inch polished tips.
Mishimoto also has an option for this system that ends in black tips as well if you aren't that into the polished tips. This is gonna make for a very big change in the exhaust note. After the resonator, you're not gonna have any exhaust filtration whatsoever. You heard in the sound clips, this is going to be much louder than stock and deeper sounding. The good thing about this axle-back though, is that if you want it to be tame, it can be, but it gets rowdy when you lay into it. It's nice, in my opinion, when you get a sound which changes like this one.
You get more of a range of tones and sound to enjoy, and you don't have to worry when you're idling or lightly cruising that your car is too loud. You do come across a little bit of drone with this axle-back. It is a muffler-delete system, so I'm personally not surprised by that fact. It's definitely not the worst drone that I've ever heard, but it is noticeable. And as far as sound inside the car, you can hear that you have an after-market exhaust in the car, but you don't get the same sound on the inside. It's much more toned down. This makes the drone not that bad, so it's not a deal-breaker, in my opinion.
That being said, and after you guys heard the sound clips, I'm going to label this one as a four out of five on the loudness scale, with 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're getting this volume in the 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 gonna 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 inlet that this axle-back has, being that it's made for the stock exhaust.
I mentioned earlier that this axle-back is stainless steel. Stainless steel is the best option when it comes to exhaust, if you're looking for corrosion resistance and a long life from the product. It's gonna have property advantages over other materials like aluminized steel, and it's going to hold up much better over time. If you want to pick this axle-back up, you're gonna expect to spend right about $400 for either option.
Now, like I said earlier, you do see muffler-delete systems costing less than normal muffler assemblies, so I'm not surprised by this. There are other muffler-delete offerings out there that cost in the same price range, and I always suggest you check out a few others just to make sure you really like this one.
We're gonna 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 gonna 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 to mark where you'll be cutting, so you don't make a mistake. The new axle-back will come with new plans for you, so you don't have to worry about that. When you go to install your new setup, it will probably be easiest to leave everything loose until you have it all lined up, and then tighten it down.
Wrapping things up with a Mishimoto Race Axle-Back system, this is a stainless steel muffler-delete axle-back. It's designed to be used with the factory exhaust or an after-market exhaust with the same diameter and it delivers a ton of sound.
