Review & Install Video

Hey, guys, Stephanie with americanmuscle.com here with my overview and install of the Pypes Street Pro Touring Axle-Back Exhaust fitting 2015 and up EcoBoost Mustangs. We're gonna be talking about a few different things with this exhaust today. But mainly, we'll talk about the sound of the axle-back and the install. The install for this is easy. It's gonna be a two out of three wrenches on the difficulty meter, since there is some cutting involved. But I'll get more into that later. The Pypes Street Pro Touring Axle-Back is going to be a good option for you if you're looking for more of a budget-friendly axle-back that still delivers the stainless steel materials and still has more of a standard muffler design. The majority of the less-expensive axle-backs are for a muffler delete system, but the Street Pro Touring Axle-Back doesn't fall into that category. So if you're looking for a system that wakes up the EcoBoost, but that isn't too loud and that doesn't have drone, then you're in the right place. The sound that this axle-back offers is what I consider a smooth sound. It's not raspy and loud, but more deep and smooth. It's not loud just to be loud. Now, it's obvious with the EcoBoost that you're going to get that four-cylinder turbo car sound, but there are some axle-backs that really enhance that sound. This isn't one of them. It's still a turbo four-cylinder sound, but it doesn't sound exactly like an import, which makes it a good option if you're trying to avoid that type of sound. Like most aftermarket axle-backs in the EcoBoost, this one is going to make the turbo more noticeable. You get a ton of blowoff and turbo noise with this axle-back. And honestly, I don't think that's something that you can get away from with the EcoBoost. You're opening up that turbo, and as a result, you make it more noticeable. This is a 409 stainless steel axle-back like I mentioned earlier, and it's also mandrel-bent. It has 4-inch polished stainless steel tips as well. Pypes does also offer this system with black powder-coated tips instead, if you guys like that look better. These systems are gonna have slightly differently prices, but I'll talk more about that in a minute. And I always say this, but stainless steel is always a great option for the cars that see all different types of road conditions, because it offers great corrosion resistance. Overall, this is an axle-back that doesn't have a ton of raspiness and popping to it. I will say, though, to keep in mind that this can get even louder in the mid-pipe and headers. With that being said, I'm gonna give it a solid three out of five on the loudness scale. At the end of the day, though, no matter if you love the sound or you hate it, it really all depends on what you're looking for and what you like. And luckily, there are quite a few options out there. When we start to look at price, like I mentioned earlier, this axle-back is on the more budget-friendly side. If you like the look of the black tips, you can expect to spend right about $500 for this system, while the polished stainless steel tips cost about $30 less. Either way, both systems are very affordable when you compare them to other options. But just like I say with every axle-back, if this isn't what you're looking for, feel free to check out some of the other options, since there is a lot to choose from. You'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. 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 measure where you'll be cutting so you don't make a mistake. The new axle-back will come with new clamps for you and two built-in tips, 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. Overall, the Pypes Street Pro Touring Axle-Back is a good option for someone looking for a stainless steel system that's going to help with exhaust tone, but that isn't gonna be too rowdy. This is a mandrel-bent system with 4-inch polished stainless steel tips or black powder-coated tips. You can check this axle-back out more online for yourself. And for all things Mustang, keep it right here at americanmuscle.com.

Deep Aggressive Sound. Wake up the anemic sound of your EcoBoost Mustang with a Pypes Street Pro Touring Axle-back System. Pypes Street Pro Touring Mufflers were designed to provide a deep aggressive exhaust note when goosing the throttle and a pleasant mellow sound while cruising, with no interior drone.

Stainless Steel Construction. Pypes manufactures its Street Pro Touring Axle-back Exhaust from 16 gauge 409 stainless steel tubing for long lasting durability and excellent corrosion resistance. All Pypes Exhaust Systems feature smooth mandrel bent tubing to eliminate any power robbing kinks. Complete with a set of brightly polished stainless steel 4" tips, this Axle-back also adds bold muscle car styling to your Mustang.

Cut & Clamp Installation. The installation of this Axle-Back Exhaust system requires cutting and removing the factory muffler assemblies and clamping the new muffler assemblies in place. Clamps and instructions are provided.

Application. This Street Pro Touring Axle-Back Exhaust System with Polished Tips is specifically designed to fit 2015 to 2017 EcoBoost Mustangs, including both the Fastback and Convertible models. Cutting the factory exhaust is required for installation.

In the installed video, the tips look like they are sagging from the bumper. Is this how this exhaust is set up or does that vary on the install?

JohnS

  • When installed, the tips do not sag. The hangers of this exhaust is different than the stock exhaust and since the cans are of a shorter length it gives you an illusion that the exhaust is sagging. Hope this helps!

Hey a friend of mine is selling this same Ecoboost exhaust. I wanna know if it will fit my 2017 v6??????

Tshome

  • Unfortunately, this axle-back is only designed to work on an Ecoboost. It will not fit properly on a V6. You will need the Pypes Street Pro Touring Axle-Back Exhaust (15-17 V6), item # 390322B, (http://www.americanmuscle.com/pypes-street-pro-touring-axleback-1517v6.html).

I am really interested to hear what this sounds like on the 2015 Mustang. I do not want the raspy sound and like the deep Sound. Are you all planning on making a video of this product?

Pr3dsfan

  • There may be a video in the future for this axle-back. I suggest going onto Youtube and looking up this exhaust on a 2015 Mustang. There may be multiple exhaust clips that can help give you a better idea of what this will sound like on your car.

is there any axle back exhaust that does not have to cut factory set up?

Smedlap

  • Sadly we do not have a axle back that will be a simply bolt on. All of the axle backs we carry will require cutting the factory axle back off.
