Justin: The Roush Axle-Back for the S197 here will be for the owners who wanna be heard as this extremely popular system will also be highly rated in the volume department as you guys just heard with our sound clips. Now interested '11 to '14 GT or '11 to '12 GT500 owners can look forward to a solid mix of 409 and 304 grade stainless all for right around the low $700 price point. Now the install itself, 100% bolt-on job, guys. So therefore, figure a soft two out of three wrenches on the old difficulty meter and let's call it an hour or so to complete from start to finish. But as always, hang with me for a little bit and we'll walk you through this job later in the video.So, the Roush system that we have here today is by far and away one of the most popular axle-backs available for the S197 GT and GT500 with well over 100 five-star reviews from a lot of happy customers. Now a big reason for the popularity with the Roush system in particular is the combination of loud and unique tone along with the, I would say, somewhat affordable price tag when compared to some of your other axle-backs in the category. But let's not waste any more time here. Let's dive head first into that signature Roush tone that you guys heard at the top of this video and listen, as you heard with those clips, you're gonna get plenty of volume here out of the Roush. This thing is certainly not gonna disappoint and as such, I feel like that's a reason for its soaring popularity.But breaking out my patented and very official wake the neighbor scale, I've got the Roush coming in pretty high here, guys, at a strong four out of five which is very impressive by the way for an axle-back by itself. Now with that being said, if you do eventually maybe swap out those stock manifolds for an aftermarket set of headers, well, you can expect that number to shoot up pretty dramatically. Now inside the car, listen, when things are that loud outside, you are destined to hear it on the inside as well. Certainly not whisper quiet but I would definitely not refer to this as offensive drone or anything like that.So how does the Roush system achieve this very unique and neck snapping tone? Well, the star of the system no doubt will be the hollow chambered muffler designed from Roush which is going to allow for all of that volume but without the use of any internal packing. So, you're not gonna have to worry about that sound kinda degrading or changing on you over the years.Construction wise you are getting a mix of 409 grade stainless I would say for a majority of the system here but Roush does include or incorporate a little 304 grade stainless for the tips themselves along with by the way a unique chrome flashing process which Roush claims will make for a more durable finish, more long-lasting finish over the years. Now if for whatever reason you might prefer a different look, maybe you wanna save a few bucks, well then, hey, you could always check out Roush's black tip axle-back. Essentially the same exact system that we have here, guys, but with black tips instead. You can find it on the site and will actually save you about 100 bucks compared to the chrome tip option.But what do you say we shift gears and get into the install as promised earlier, guys? And thankfully, axle-backs for the S197 GT and GT500 will be a direct bolt-on modification with no cutting needed. Now to give you a better idea of just what you're in for in the garage or driveway, feel free to check out our detailed walkthrough and tool breakdown now.Man: Tools used for this installation: 3/8 electric impact gun, exhaust hanger removal tool, 1/4-inch drive extension, 13, 15-millimeter sockets, and PB B'laster. So, first thing we're gonna do in our uninstall is now we've got our vehicle up on our lift, we're gonna remove our 13-millimeter clamp in the back here holding our muffler onto our axle pipe and then we'll go into removing our 3 hangers on our grommets to remove and drop down our muffler. So now I'm gonna take my 13-millimeter on my 3/8 gun to loosen this clamp up and then that will get it off of the axle pipe.Now that I have that loose, we'll be able to pull it off of this and break it free and move this out of the way just like that. And we'll drop our clamp. Now your clamp might be welded onto your pipe. Ours was already cut and off a couple times. I'm just gonna actually take that ours and move ours out of the way. So next what I did was I took some spray penetrant, PB B'laster, sprayed our three grommets. There's one here, two in the back. I'm gonna take my exhaust hanger removal tool and get in here and pop this one off first. And that'll get the muffler down. And then we'll be able to slide the muffler back and get it off the two back rubber grommets. So now with the pipe out of the way, and I sprayed PB B'laster back here on our two rubber hangers that hold this up, I should be able to wiggle the muffler out of the hangers. And drop the muffler down. Now you're gonna wanna just repeat the same procedure on the other side.So now that we have our old muffler off, I'm gonna make sure I put my clamp on our new muffler and I'm gonna slide it up into place here, get it started into our rubber grommets on both sides. And once I have those in place, then we're gonna go up to the front and install our front one.So, we got the back ones in place. Now we're gonna push the front one on and get our front one in place. Pretty much just like that. Next, we'll tighten up our hanger in the back. So now we're gonna take our clamp, make sure everything's in place, and take our 13-millimeter on our 3/8 gun and give our clamp a good snug here. And now you're gonna wanna repeat that same install procedure on the other side.Next, we're gonna install our tip. We're gonna put our hanger on our tip, slide it in place, line our tip up where we want it, and I'm gonna hold our tip right where I see it. I'm gonna take my 3/8 gun on my 15-millimeter and tighten up our clamp. Now you're gonna wanna just repeat that same procedure on the other side.That wraps up this review and install of our Roush Axle-Back Exhaust for '11 to '14 GT and '11 to '12 GT500s.
