Review & Install Video
Hey, guys. Adam here with americanmuscle.com. Today we're taking a closer look at, listening to and installing the Roush Performance Cat-Back Exhaust with Black Tips available for the 2018 and newer Mustang GT without the active exhaust. Now, before we get any further, guys, if you have the active exhaust S550, this one is not gonna be for you, it's not gonna fit, it's not gonna retain that function, but there are a ton of other options in the category for you. This one here for my non-active guys, as you heard from our sound clips, I'm gonna give it five out of five on our loudness meter. I'm gonna let you know right now. Cold starts in the morning, forget about it. Your neighbors are not gonna like you, it's going to wake them up, it's gonna wake their kids. They're not gonna like it, but who cares. This thing is gonna make a ton of noise all throughout the RPM band. At idle, it's got a nice deep throaty rumble. As you get on it through the lower end of the RPM band, it's gonna snap, crackle. It's got a couple of pops, it's got some gurgles in its voice. That's what I like to hear when it comes to an exhaust like this. If you're with me, Roush is gonna be the way to go.
As you start getting to wide open throttle, it's gonna be all out volume. Five out of five. It's gonna be the loudest option in the category among some of the few like the Corsa Xtreme and Borla ATAK. This is gonna be a player in that category, in the five out of five. So, if you're looking for volume while still keeping a really aggressive, really high-quality sound, this is a really good way to go. It is a little bit on the raspy side, but because it's got an X-pipe integrated as the midpipe, you can expect that. It's got pretty much a straight pipe. Now, there are high-flow mufflers here, the bullet style mufflers. Little bit of baffling inside so it's not quite straight pipe but that's gonna help produce that high-flow tone while allowing your exhaust gases to exit quickly. Power and torque gains with this option here you can expect a little bit of a throttle response. It comes in right around $1,200 for the price tag. That's something you can expect with a premium brand like Roush. 304 stainless steel throughout, about two and three quarters-inch diameter for the tubing, mandrel bent, kink-free unrestricted tubing. That's a huge player in the category. Sol it's going to be a lot more high-quality than some of the more budget-friendly options, it's gonna be a lot more durable as well. Now, you're retaining the quad chips out the rear end. This one's got black powder coated tips, the Roush emblem right on the outside tip right here. I think it's a really good touch. We'll take a closer look at the details of the kit a little bit later on when we have a stock comparison on the ground here to my left.
Now, if you wanna get this installed, two out of three wrenches on our difficulty meter. I would say anybody can tackle it. You wanna have a little bit of mechanical expertise on deck, but really if you have the right tools and you have a little bit time and patience you can get the job done. No cutting, no welding, no permanent modifications, it basically bolts right up in the factory location in a bunch of little pieces. It's really not that hard to do. I'm gonna take you through every step of the install. Took me about two hours. What do you say we get started?
Tools used in this install include an impact gun or a ratchet, an extension, 13 and 15-millimeter deep sockets, flathead screwdriver, and a mallet.
Now, the first step of the uninstall here under our 2019 GT is to loosen up both of the band clamps holding your stock exhaust to the headers. Now, what we're gonna do is grab a 15-millimeter deep socket and loosen up the two bolts here and on the second one. Now, we're not gonna fully remove them, just get them loosened up so we'll be able to slide the rest of the exhaust out of place. Now, the next step here is to go right under your crossmember here and we're gonna remove the brackets holding our factory hangers to the frame. Now, these are 13-millimeter bolts. You have the option of sliding the hangers out of these brackets, but I find it to be way easier to just grab an extension and my 13-millimeter deep socket and get these bolts removed. Go right on over the rear sway bar. Just pull those bolts out. You wanna keep these because we're gonna have to reuse those once we install our next exhaust. Now, with those bolts removed, these brackets are actually hooked on to this crossmember, so we're gonna lift up and just unhook them and just rotate it down out of the way. Same thing on both sides.
With the clamps by your factory manifolds or your headers loosened up, we've got the frame disconnected from those brackets on the hangers. At this point, we're gonna disconnect the stock exhaust from the headers and I got my buddy Scott here to help me lower it down. If you're working on the ground on jack stands, it's gonna be a little bit easier for you to do by yourself. But since we're so high up in the air, you're gonna wanna have a buddy with you if you're working on a lift. So, once we get these disconnected, we're just gonna slide the whole factory exhaust out of the hangers by the exhaust tips toward the front of the vehicle, then we'll be able to set it aside.
All right. So, we got our factory exhaust off of our 2019 GT and it's on the ground next to the Roush Performance cat-back. I wanted to take you through some of the similarities but mainly the differences between the two kits starting up front. Now, as you can see on our factory exhaust, we have that resonator where your midpipe is. Now, that is going to demolish some of that sound that you would otherwise get from your 5.0. Now, from the factory, it does sound pretty good, I will say, but removing that resonator is gonna open up some of that volume and open up some of the airflow reducing restriction. That's exactly what we're getting here. We have an aftermarket X-pipe, two and a half-inch tubing. And the X-pipe there being welded in the center is gonna allow for crossover of the airflow which is removing a lot more restriction, it's a lot more free-flowing. That's gonna translate the horsepower and torque that you can feel. That, in addition, is gonna give you a raspier and louder tone than what you'd get with a factory resonator or an aftermarket resonator and, of course, an aftermarket H-pipe.
Moving along from there, the rest of the system is a two and a half-inch tubing, all mandrel bent. Mandrel bent meaning it's got a seamless bend to it. All the bends are kink-free allowing the airflow to move more freely and quickly. Moving on, you'll see that we don't have resonators anywhere in between. The next best thing we have is our mufflers here by the tips. Now, the mufflers here are a huge difference in size. These factory ones are massive. The new bullet style option from Roush is a lot smaller, a lot more compact. But inside of those mufflers are technology baffling to make sure that you're getting a really good quality sound, not a lot of distortion, it's gonna minimize some of that drone while also keeping it at an aggressive tone, deep, throaty, aggressive tone. The tips are something that I really like to highlight here. Factory chips are slash cut, they look pretty cool but they are really thin, they're not very aggressive. The new tips here are twin 3-inch so you retain that quad tip functionality but it's also powder coated black on top of a 304 stainless steel. That's gonna be a little bit thicker than the walls of your tubing here. So, it looks really aggressive, it's got that thick bulky feel at the rear end. And the black I think blends in a lot better with your factory valance. If you opted to go with any other aftermarket trim at the rear, the black I think blends in with a lot more so than the chrome or polished tip. They do slightly retain the slash cut. It's not gonna be as prevalent as your factory slash cut. And the last thing to note here is on the side, there's a small Roush logo printed right on the side of the tip. That I think is one of the cleanest branding I've seen with exhaust tips. A lot of times it's really large across the top. This is just one tip all around the outside. You can see it from the side profile of the vehicle. I just think it's a really nice subtle touch by Roush.
Now, we do have something to move over from our factory to our new one. The brackets on the factory hangers right underneath the subframe, we removed those all in one piece. I think that's a lot easier. We're just gonna pop those off and transfer them over to the new hangers and then, of course, we have to move over the factory clamps to the headers or the manifolds and then we'll get to installing our X-pipe. Now, in order to pop these off, I'm gonna use a hanger removal tool. You can do it by hand but I'd recommend using some PB B'laster or WD-40 to loosen them up. Now, put the tool right in place, squeezes them right off. All right. Now, we can transfer them over. Now, when you're reinstalling these onto your new hangers over by Roush, you wanna make sure this little tab at the top is facing the front of the vehicle. Slide them into place, just rotate them down and out of the way.
Now, when you're installing your band clamps, you wanna make sure that the locking tab here is meeting up with the little button that's welded on the stock manifolds, they're kind of retainer tabs. Now, we're gonna reinstall this up here, slide that into place. If you need to, just try to separate them and loosen them up, slide them right into place. Do the same thing for the other one.
Next up is our X-pipe. You want to install that right into the clamps. Grab a 15 socket and tighten down the clamps. All right. The next pipe going under our subframe connected to the hanger isolators is gonna slide in, you wanna make sure you have a clamp over the end here. There are two and a half-inch clamps available in the kit. Slide that over then install your pipe. You wanna make sure you're seating it all the way back. It might give you a little bit of a struggle but go back and forth, you'll get it to seat all the way in. All right. Rotate it where you think you need it. Grab your 15 socket and tighten down the clamp. All right. Now, you can do the same thing for the driver side. All right. From here, we're gonna rotate these brackets upward and reconnect them to the subframe. So, lift up on the exhaust, they'll hook right in. Take the factory 13-millimeter bolts, thread those in by hand. Grab an extension and a 13 socket and tighten them down.
Now, starting on the muffler on our passenger side, you wanna make sure you're sliding the hanger in first and then lining it up with the piping on the other side. Once you get that seated all the way, rotate your clamp up and tighten that down with a 15. Now, you can repeat for the driver side. Now, if you need to, you can grab a mallet and tap on the outside here to get it to seat properly.
Last steps, install our tips. You wanna make sure you have clamps on the end here slotted into place on the muffler outlet. You don't really have to worry about the positioning just yet, try to get it as straight as possible. We're gonna get this little snug and then we're gonna go back and make adjustments. We might have to loosen up some clamps, rotate it upward to get it closer to the top here. We'll make adjustments when we're done. Just loosely install everything. Once you get this in place, we'll make adjustments. All right. On our driver side, same thing. All right. Now, if you need to, go back and make adjustments and you're good to go.
Well, guys, that's gonna wrap up my review and install for the Roush Performance Cat-Back with Black Tips for the '18 a newer Mustang GT without active exhaust. Now, if you want to get this one, you can do so right here at americanmuscle.com.
