    Review & Installation Video

    Review & Install Video

    Now, first and foremost, guys, this will be for anyone looking for a considerable bump in both volume and tone over the factory system, but that's kind of a given with any aftermarket exhaust. Right? I would say the LTH will be for the owners who want to grab a premium cat-back, in regards to materials and build, from the 304-grade stainless to the beautiful weld, and most importantly, the company's proprietary Titan finish. It's that satin coating you're seeing all over everything here. According to the gang over at LTH, it's going to further help reduce the corrosion. But most importantly, it's going to help strengthen the welds and the materials themselves. Now, the LTH's straight-through-by-design mufflers and included X-pipe will produce a surprisingly deep tone overall, but with zero drone to speak of at any RPM level. The premium materials and the corresponding proprietary coding will elevate the price slightly to the $1,200 mark, and it's going to get a one out of three wrenches on the difficulty meter from me, with a little bit more detail later on. Now, at first glance, LTH calls this their mid-exhaust and axle-back system, which might seem a little confusing to some of you guys watching, because it looks like a standard cat-back, and for those most part it pretty much is. However, LTH takes a very modular approach to designing and building systems, meaning you can add one part, and then another, and then maybe even incorporate some Long Tube Headers into the equation eventually. But for the purposes of this video, we're going to be focusing in on the mid-pipe and the axle-back portion here. But let's talk about the sound from said combination here. What can I say, guys? I'm a fan of the LTH, plain and simple. A nice, deep, thumping tone, even with that X-pipe in place. Not the loudest system out there, but it will certainly turn a few heads. So going to my Wake the Neighbors scale, a strong, a healthy three out of five on my one to five, or One to Wake the Neighbors scale. I think this is a great daily driver-friendly system, and here's why. You're getting some bark. You're getting some noticeable increases over the factory system. But again, it's very quiet on the inside and it's definitely not going to drive you crazy on long trips. Let's take that daily driver thing a step further and really focus in on the lack of drone. Because I'm sure a lot of you guys out there, when shopping for a system, you want to get something that, yes, it sounds great on the outside, but you don't want it to drive you crazy on long trips. I'm happy to report, LTH, they did a great job with this particular system. Great tone on the outside, but inside while cruising, nice and quiet, and nice and enjoyable, even on the highway, 6-gear, 2,000 RPM, this thing was very enjoyable inside the car, and certainly again something that would be great on any daily driver out there. But let's move away from the sound a little bit here with the LTH and kind of shift our focus over to the materials and construction. Listen, guys, you heard me talk about this at the very top of the video, LTH comes correct. They bring some proper materials, 304-grade stainless, pretty much the best stuff you can buy when it comes to the world of aftermarket exhaust systems. Then, they finish everything off in their trademark Titan coating, which again is that kind of satin silver that you see here at the bottom. Listen, guys. I've been through LTH. They're really not all that far from us here on the East Coast. Yes. They're a smaller outfit compared to some of the other brands out there. But at the same time, their level of detail is very impressive and that is evident with the final product. Even more impressive, again, this trademark Titan coating. It looks really cool, but there is actually some function to this as well. According to the guys, it strengthens the material a little bit more, more specifically those welds. So you shouldn't have to worry about any failures or cracks over the years with their products. Now, aside from that 304-grade stainless and the Titan coating, you're also looking at two-and-three-quarter-inch mandrel-bent tubing throughout, guys, including the X-pipe, all the tubing of course, straight-through-by-design mufflers, we already mentioned that earlier on, bringing up the flow a little bit. But don't think of this as a big power-adding modification. That's simply not going to be the case. You're just looking at a sound and a slight visual improvement here as well. Now, everything is going to exit out the black tip version of this exhaust, which we have in the video. Just a heads up, you can grab this with a more traditional silver tip on the site. It's actually going to save you about $100 in the process when doing so. But for the black tip system that we have here, right around $1,200, which I personally think is very fair given the level of quality and the level of materials here, with this particular system. Switching gears, let's briefly graze over the installation process here with this cat-back, and cat-backs in general on the S550, 99% of the time, going to be a very easy day in the shop or garage for you. A straight up bolt-on job, no cutting, no permanent modification. Therefore, one out of three wrenches on the difficulty meter, maybe a couple of hours from start to finish. As far as your tool list, well, basic stuff here as well. A socket set is going to be doing most of your work, guys, in addition to getting the car up in the air, of course. A lift will be your best bet, but a jack and jack stands will suffice. Last but not least, I always like recommending having a little spray lubricant on hand to help you with some corroded bolts. Hopefully, that isn't the case on your new S550, in addition to helping you with some of those rubber exhaust hangers. First things first, that factory system needs to get out of the way to make room for the new LTH here, so grab your 15-millimeter socket and your driver, loosen up the four bolts at the clamps near the resonator, and slide them back. With the clamps loose, go ahead and move towards the rear subframe of the car, and remove the two 13-millimeter bolts holding the hangers onto the rear subframe assembly, and at this point you can drop the entire system from the car. Once that factory system is out of the way, you can get to work installing the new LTH system here in reverse order. Now, I always like to recommend starting from front to back. So that would mean installing your X-pipe first. Secure it with the clamps, but don't tighten it all the way yet. After that, install the intermediate pipes, followed by the axle-back portion here, again, using the included clamps the whole time. Again, save your final tighten up to the very end. This way, it'll allow you to tweak those pipes a little bit, get those tips exactly where you want them in the opening, and once that is done, go ahead and hammer home those clamps and your installation is complete. Wrapping things up, the LTH system gets an A-plus from me for materials and construction. That Titan coating sure looks sexy and is actually functional. Last but not least, that tone was a fan favorite here, at least in the shop, and I'm sure you guys will dig it as well. So that is my review of the LTH system, which you can grab right here at

    Aggressive Race Sound. Unleash the beast hiding under the hood of your S550 Mustang by upgrading to a LTH Cat-Back Exhaust System. This LTH Mid Exhaust & Axle-back Exhaust Kit will quickly convert your 2015-2017 GT Mustang's quiet, tame exhaust - which certainly does no justice - into a racing-inspired, growling howl complete with X-pipe and LTH Mufflers.

    Power And Performance. LTH's Cat-Back exhaust not only improves the sound of your 5.0L V8 powered Mustang, but it will also improve its performance. With the help of its free flowing "straight-through" muffler design and high-flow cross over X-pipe, this Cat-Back will significantly improve exhaust flow for an increase in rear wheel horsepower and torque.

    Stainless Steel Construction. Manufactured in the USA from mandrel bent 304 stainless steel tubing for it's durability and corrosion resistance, this LTH Mid-Pipe and Axle-Back features two "straight-through" perforated mufflers with massive 4.0"" diameter 304 stainless steel tips in a cool black finish for impressive muscle car looks and sound.

    LTH Titan™ Uniform Satin Finish. Titan™ is LTH's unique proprietary process that produces a bright uniform satin finish over the entire part to eliminate the ugly discoloration from welds, heat, and scratches that are encountered during manufacturing; making it the perfect exhaust finish for high end show cars. Not only does the process create a show quality finish, but it also strengthens the stainless steel to eliminate microscopic sharp edges created during welding that could, if not removed, become tears and cause the product to fail.

    Direct Bolt-On Installation. LTH engineered their Cat-Back to be a direct bolt-on upgrade replacement. This LTH Mid-Pipe and Axle-Back System will easily bolt straight up to the factory piping without any cutting, modifications or special tools required for an easy straight forward installation.

    Application. This LTH Mid Exhaust and Axle-Back Exhaust System is specifically designed to fit the 2015-2017 5.0L GT Mustangs equipped with either OEM Exhaust Manifolds or LTH Long Tube Headers.

      Nice Quality, Good Sound Quality

      Very recently purchased and installed this catback. Overally quality of the system is very nice, the 'satin' finish looks good, and the 'Long Tubes' detail on the black exhaust tips is a nice touch. The exhaust sound has a nice aggressive tone, but with no real drone to complain of. Definitely a lot better than the stock system and a great upgrade!
