Review & Installation Video

Review & Install Video

Hey guys, Stephanie with americanmuscle.com here with an overview and install of this Roush Cut and Clamp Resonator Delete X-Pipe, available for 2015 and up GT Mustangs. In this video, we're gonna be talking about a few things, including the sound of this X-Pipe and the install. I'll talk more about this later, but the install for this is gonna be a two out of three wrenches since you will need to cut. This Resonator Delete X-Pipe from Roush is going to replace the factory resonator that's restricting to the new GT. It's gonna be a good option for someone that's looking for a stainless steel mid-pipe that's gonna open up a good amount of sound easily and quickly. Swapping out the resonator-style mid pipe for a traditional style mid pipe like this X-Pipe is a way to get around having to purchase an entirely new exhaust system in order to make a big change in the tone of the exhaust. The factory resonator style mid pipe is basically another muffler on the S550 GT, that muffles sound and power. So, by eliminating this muffler or the resonator style mid pipe, and replacing it with a standard type of mid pipe that's free-flowing like this X-Pipe, you're getting rid of a bottleneck. And you can expect a good amount more volume from the exhaust even without changing the factory axle-back or any other components. This X-Pipe does reuse the factory cats, so you're still gonna be smug legal and still pass emissions and get the change in sound that I've talked about. So, that should give you a good idea of just how restrictive the factory mid pipe is. This is stainless steel X-Pipe and material is something that you should always consider when you're shopping for exhaust. So, the material of the mid pipe is really gonna drive the price point. And this X-Pipe being stainless steel, is gonna drive up the price point a touch. But stainless steel does have some upsides to it. This type of material is gonna last much longer and have much better corrosion resistance than other materials like aluminized tubing. If the material and life span aren't something that you're concerned about, or you live on the West Coast or your car isn't a daily, then it may not be a big deal to you. If you're looking for a long-lasting system that can handle the weather, you're better off shopping for something made with this type of material. This is a cut and clamp mid-pipe which means that you cut out and remove your factory resonator and clamp the X-Pipe into place. That's how you are able to reuse your stock cats. But, it also means that you can pair it with your stock mufflers or you can run it with an aftermarket axle-back. So, no matter what axle-back you have, this X-Pipe will work for you and either way, you'll still maintain the use of the stock cats, and you'll still have an improvement in sound. As far as sound goes, this is an X-Pipe and like a typical X-Pipe, you can expect more of a raw spear tone from your exhaust and more volume. If you want more of a deeper note as opposed to the raspy sound, you should stick with an H-Pipe setup instead. And there are a few cut and clamp H-Pipes that are currently available. H-Pipes tend to be a little deeper sounding, while X-Pipes produce a bit more volume with that raspy note. On a scale of one to five, with five being the loudest and keeping in mind that you're still gonna have your stock cats and axle-back, I'd rate this X-Pipe as a two. Of course, if you ever change your axle-back or even your headers for that matter, the X-Pipe is gonna change in sound and volume so, just keep that in mind. Depending on which axle-back you end up going with, you could be looking at more of a three or four on the loudness meter. So, if you don't want a system that's too loud, just keep in mind this mid pipe when you're shopping for other components. Another thing to mention here is that a great side effect of replacing that resonator with an X-Pipe is dropping a good amount of weight. The factory resonator adds some pounds to the S550. So, by replacing it with a simple X-Pipe, you're gonna be dropping about 12 pounds which is just another little plus here. As far as price goes with this X-Pipe, you're looking at spending between $200 and $300 for it. Now, this is one of the more expensive options out there, so there are other X-Pipes that are available in other brands, other materials, and at other price points if you wanna shop around for something else. Either way, swapping your factory resonator out for an aftermarket X-Pipe is a fast and easy way to totally change your exhaust note. As for the install, like the name suggests, there will be some cutting involved but nothing too difficult. Take your time, it's gonna take about two hours to complete maybe less, I'm gonna call it a two out of three wrenches on the difficulty meter, but mainly just because of the cutting that's involved. As usual, a lift would certainly make the install easier and you will need something to cut your exhaust with, so keep that in mind before you start the install. The X-Pipe does come with brand new clamps for the rear, you'll reuse the factory front clamps. But you always have the option of clamping the front and welding in the rear of the pipe if you want, but that's up to you or your shop. A lot of people like welding in the rear better, but that's not something that you have to do. So, wrapping this up here, this is a stainless-steel Resonator Delete X-Pipe that can work with either the factory axle-back or an aftermarket one. It also works with the factory cats and it's gonna create some sound and volume from the GT. It's a great way to inexpensively change your exhaust note and as always, you can check it out more online for yourself. And for all things Mustang, keep it right here at americanmuscle.com.

roush x pipe

Had a ford racing x pipe before and didn't get the sound I wanted. Switched to the roush x pipe and loved it so much I then added the roush axel backs the combination brings compliments daily.

excellent Sound

This is a must have if you want your exhaust louder without getting rid of your "cats" Twice as loud than with the resonator. Absolutely love the high tech race car sound that it gave my Roush S3

How much louder is this with the stock mufflers?


  • The increase will be moderate with consideration of the use of the stock mufflers. This Roush Cut and Clamp Resonator Delete X-Pipe will completely remove those resonators. Sound is subjective so we would recommend listening to a few sound clips of the x-pipe with stock mufflers to ensure this is a sound that meets your desired sound quality.

I just installed the Roush axle back exhaust without getting the x pipe, if I now get the x pipe would it still fit the same?


  • The Roush Axle-back will still be able to fit the same after the installation of the Roush cut and clamp resonator delete X-pipe.

Will this fit a v6? I see it says GT


  • The Roush Cut and Clamp Resonator Delete X-Pipe is specifically designed for the GT's only. Many enthusiasts have installed this x-pipe on their V6, however, we would not be able to guarantee fitment as was designed for the GT only, by Roush.

Is this long enough to mate directly with the roush axle back (quad tips) or would i still need to cut a segment of factory pipe to connect the components?


  • Hey kevin, So you would still need to cut part of the piping in order to slip this on!


Helpful (0)

I already have an h pipe on my car with the Roush axle back exhaust. I'm going to switch to the x pipe. I have a tune on my car. It won't make a difference with the tune when I switch, right?? Like I won't have to call and get a new tune just because I switched to an x pipe?? Probably a stupid question, but just wanting to make sure.


  • You will not need to retune your vehicle when you are switching from an H-Pipe to an X-Pipe.

Hi, Will I need to tune my car if I get this Roush resonator delete x-pipe? Thanks!


  • A tune is not required for this x-pipe. though, it would be a good idea to get one so that your car makes maximum power.

    Sounds good.

    Added to the Roush Axle Backs and they sound mean. Puts a smile on my face and it turns heads as well.
