      Video Review & Installation

      The Flowmaster Outlaw Series axle-back exhaust is for the 2015 and newer EcoBoost Mustang owners out there that are looking for an axle-back that'll be more refined and deeper sounding and is made from stainless steel with one of the most budget-friendly price points. So Exhaust for the S550 can get expensive fast, even axle-backs, but this is one of the more affordable options that still offers stainless steel materials. The install for this is easy. It should take you about an hour to complete and it's a two out of three wrenches on the difficulty meter since there is some cutting involved, but, of course, I'll get more into that later. One of the more important things when it comes to shopping for exhaust is going to be the sound. Like I said, consider this as one of the more refined sounding axle-backs for an EcoBoost. It gives more volume and more sound for sure and it's deeper than the stock exhaust, but it steers away from being obnoxious. A lot of times when systems provide a ton of volume increase for the EcoBoost, that's when you really start to get into the import sounding exhaust. If you're looking to steer away from that, this is one of the ones that you're gonna want to consider. Of course the EcoBoost is a four-cylinder turbo car, so that's what it's gonna sound like ultimately. I would call this system a three out of five on the loudness scale, with one being a quiet upgrade and five being a very loud upgrade. You do get more turbo noise with this axle-back since you are opening up exhaust flow around that turbo, and there is an occasional crackle on decel. Still, you don't have to worry about any drone in the interior with this axle-back. You're looking at two and half-inch mandrel bent tubing with this axle-back, which means that Flowmaster did step up the diameter here. The stock exhaust had a two and a quarter-inch diameter. This is made from 16-gauge 409 stainless steel tubing which is gonna be nice for those of you out there that are looking for an exhaust that'll have corrosion resistance and a longer life. Stainless steel will always last longer than aluminized steel would and will hold up better against corrosion. This system finishes with four-inch polished stainless steel tips. Price-wise, this is one of the more affordable options if you look at everything that is currently available. You can expect to pay a little over $400 for this axle-back, which is a good price considering the materials that you have here. Axle-backs for the EcoBoost range anywhere from just over $400 to nearly $1700. And as always if this one doesn't have the sound that you're looking for you have a ton of other options to check out. You're gonna be looking at the typical cut and clamp design with the install for this axle-back since you do need to cut all S550 axle-backs. I'm gonna call this a two out of three wrenches on the difficulty meter but just because of the cutting that's involved. It's nothing too difficult, but I just recommend some eye protection and a fresh Sawzall blade to make things 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 happen to have access to one. Cutting the factory axle-back isn't hard. Just be sure to measure twice and plan and mark where you're gonna be cutting the factory axle-back so you don't make a mistake. You can always mark the axle-back with painters tape if you want to, then use the Sawzall to cut the stock axle-back out. It'll probably be easiest to leave the hangers on the axle-back and just unbolt them from the car. You can transfer them over to the new axle-back then. The new axle-back will come with new clamps for you, so you don't have to worry about that. When you go to install your new setup, it'll probably be easiest to leave everything loose until you have it all lined up and then tighten it down. This is the Flowmaster Outlaw axle-back exhaust for the 2015 and newer EcoBoost Mustang, and you can check it out more online right here at americanmuscle.com.
