      Review & Installation Video

      The MBRP Black Series muffler delete 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 that has black tips. This is currently one of the most affordable axle-backs on the site and the most affordable black tip option. It's a muffler delete setup, which means that it's 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, and you're looking about two hours' time. This being a muffler delete system means exactly that. You're going to be completely eliminating your muffler. So all you're going to get with this system is the pipes you see here with the MBRP black powder-coated 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 a much louder and deeper sound than the stock exhaust. There is a little bit of drone inside the cabin at cruising speed. But honestly, I'm not surprised by that at all. The nature of a muffler delete lends itself to the drone, and it's not a terrible drone. But it is noticeable. With that being said, I'm going to call this a five 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 get 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 going to get even louder and it has the potential to be very loud, depending on what you do with the rest of your exhaust. Just keep in mind the smaller diameter inlets that this axle-back has, being that it's made from 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, black, stainless steel, powder-coated. 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 down some. 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're shopping for a daily driver that sees all different kinds 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, because you do have this black powder coating over the entire axle-back to help protect it from corrosion. When it comes to price, you can expect to pay very close to the $300 mark, which makes this currently one of the most affordable axle-back options for the S550. The MBRP Pro Series muffler delete system is the same system as this one here is, but it doesn't have the powder coating. That means it's going to be slightly more affordable, about $10 less. 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 the cutting is 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 out, 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 but the factory hangers. Once you get the hangers over to the new axle-back, you're ready to install. You just clip the axle-back into place and bolt up the hangers. You can tighten the clamps on the axle-back. But it'll 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 Black Series muffler delete axle-back exhaust. But as always, you can check it out more online right here at

        MBRP always my fave

        They get installed very easy even though munes needed to get new hooks welded but they are some of the loudest and deeper axelbacks to get on the site! Pair with an H pipe and youll love it! MBRP always wins!

      will these fit a 3 inch x pipe if you add a connection pipe to the deletes?

      • This axle back exhaust is designed to fit the factory exhaust. For a larger mid-pipe, modifications may be required.

      I've got a h pipe resonator delete my 17gt, would this make the drone unbearable?

      • Drone would be a matter of personal preference, however, this exhaust with the resonator delete will cause the drone to be worse than normal.

      So i have a custom made xpipe and a muffler delete on my mustang gt 2017 and lost back tire pressure, will this axel back improve that?

      • The axleback will not fix that issue, it is more than likely the issue of the custom made xpipe on the vehicle causing a large loss of backpressure.
