    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.

    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.

      The pipe was well-packed during shipping, included all parts. Heavy duty, solid materials. This pipe gives a bit of rasp to the exhaust note. If you prefer a deeper rumble, you might prefer an H pipe. Resonator delete, X pipe install, stock GT mufflers for the 2018 and up and you’ll likely have all the volume you want.

      Roush Resonator delete

      I have a 2015 Roush Stage 2 with the factory quad tip Roush exhaust. Adding this x-pipe makes the Roush mustang sounds aggressive and throaty without it being annoying. Easy to install, was able to do it over a two day period. Make sure you have a saw ready to cut the factory resonator off at the require length. After that it’s easy to install with jack or ramps (I’d recommend backing your car up on the ramps if you don’t have a lift). Price was good and delivered within a week after purchase. No issues at all.

      Roush delete was a perfect fit, installed easier than expected. I ended up just in unbolting and pulling out whole system due to my ramps not being tall enough. It’s almost like Ford intended you to upgrade the car!

      The Missing Link

      I bought a ‘17 GT with a Roush Power Package (cold air intake, axle-back, and tune) from a dealer last year. There was just something missing in the sound. It was far too reserved. This x pipe was exactly what it needed to “wake up.” It’s slightly louder at low rpm and idle but when you get on the gas the thing comes unglued!! I’d give the loudness at full throttle an 8 of 10 and a 3 of 10 at cruise down the highway (80 mph). Absolutely perfect. As far as quality, everything arrived well packaged and defect free. Even came with two small white Roush window decals. Absolutely a must have if you are already running an axle back set up and still feel you need something more.

      Roush X-pipe

      This is a must have mod. It's inexpensive and a perfect way to get rid of the heavy and quiet stock resonator. It's not overly loud by itself but I combined this with the Roush axle back system and that made it very loud. Install with the right tools and a lift is simple and took less than an hour.

      17 GT

      So I have the roush axle back exhaust on my car but wanted it to be slightly louder. so I bought this x pipe and installed it. great product great fit. easy installation but now it is a little too loud for me. although for some people it would be perfect just personal opinion the x pipe paired with the roush axle back sounds great and inside the car it is not bad and not that loud, completely drivable and you can have a conversation inside the car no problem . also no drone at all but outside the car it is super loud so now I'm looking for a resonated x pipe to quite it down slightly. if you like loud exhaust this is perfect.

      Warning. If paired with axle backs the combo is LOUD. Even more so if your in a convertible like I am. Truly sounds amazing just have to be aware of sound in neighborhoods. Car really woke up with add I got these on. Great low quiet sound at idol. Zero from at highway speeds. 80. But step on the gas and it roars to life!

      Well worth the money!

      Before I got these I had the roush axlebacks. Those alone sounded great, but the X-pipe gave it more a race sound! Nice and quiet on idle but when you get on the gas even the slightest it wakes up all the way. Installed it at my job(dealership) takes very little time and less brainpower easy sound mod.
