So if you own a 2014 to 2018 5.3 liter-powered Silverados and Sierras, and you're looking for one of the best cat-backs available currently, the Borla Stinger S-Type that I've got here today with me is certainly going to be at the top of the list. I say that for a few reasons, number one being fit, materials, and finish. As far as install goes, putting an aftermarket exhaust on your truck can be a little difficult, however, Borla is certainly the gold standard, from my personal experience. I say that because they ensure that all the pipes are mandrel bent to fit perfectly. They use all your factory hanger locations. And generally speaking, you won't have a tough time getting these pipes to fit together or clamp down, as can be the case with some less expensive systems. And then, again, materials, you're getting 304 stainless steel with the S-Type. Generally speaking, it is the best material available in the category. There is no higher quality stainless steel and it's actually higher quality than your factory system, which is 409 stainless. Again, less expensive options will, generally, be made out of 409 stainless or aluminized steel, certainly going to corrode and rust a little bit sooner, whereas this will continue to look really good.And then finish. Like I said, this has a very unique finish, thanks to those black chrome tips right there, polished, they are not painted or powder coated. They are an actual polished black chrome, certainly a unique finish that's not easy to find elsewhere. Now, as far as sound goes, I also think that the S-Type is one of the best sounding cat-backs available for the 5.3 liter. This falls right in between Borla's Touring system, which is a mild daily commuter system that will give you a mild upgrade in sound but it's nothing too loud. And then on the extreme end, you got the Borla Atak system, that's gonna be a strong five out of five on our loudness meter. The Stinger, I think, is really the Goldilocks of the three, it gives that perfect amount of increase in volume, I'd give it a healthy four out of five. And on the low end of sound, you're gonna get a nice deep bell tone sound, very retro and classic, in my opinion. And then when you really mash on the pedal, you're not gonna get any drone or raspy noises. You're gonna get a nice throaty street rod kind of sound. Also, that sound plays very nicely with that classic split rear exit system. Now, if you like everything that you see and hear but you want something with a little bit less flare, we do offer the Stinger system with the factory single side exit. It still does come with the black polished chrome tips so that's something to keep in mind. It does cost a little less. If you like how this system sounds and you wanna pick it up for your truck, we're gonna walk you through the install to show you how easy it is. It's a soft two out of three wrenches on my difficulty meter. It might be a little bit of a squeeze, but you should be able to tackle this in your driveway with basic hand tools. I'd say, it'll take you maybe an hour or two at most. So, without further ado, let's go ahead and throw our truck up on the lift and get started. To install your Borla Stinger cat-back, you will need the following tools, a 3/8 drive ratchet, a 13-millimeter deep socket, a 15- millimeter deep socket, and optional but helpful tools include an impact gun, some spray lubricant, and an exhaust hanger puller tool. So, first things first, we've gotta remove our factory cat-back before we can install our Borla system. To do that, all you need to do is remove this barrel clamp right here securing the system to your catalytic converter. You're gonna need a 13-millimeter socket to loosen it. So with our barrel clamp loosened, we can now start pulling the rubber isolators that hold our factory cat-back to our truck. There are four of them and you can either use your hands or you can use an exhaust hanger puller tool. It's also good to spray down these rubber isolators, make it a lot easier on you. Now, you have one last isolator back here near the tailpipe. This is the last piece holding your factory cat-back to the vehicle. So you wanna be careful removing this, wanna keep your hand on the tailpipe. Once you pull this hanger out, go ahead and let the exhaust rest on your axle, and then you can remove it from the vehicle. All right, with our factory cat-back removed from our truck, we're gonna go ahead and push it over the axle towards the rear of the bed, that way we can get the front of the connection over that crossmember. Once you've ducked that down under the crossmember, you can pull the entire cat-back from the vehicle. All right, with our original cat-back removed, now we can install our new Borla system. We're gonna start with the front extension pipe. See it has this flared end here, that's gonna fit in the original clamp you loosened earlier. It also comes with a hanger pre-installed that you're gonna fit in the frontmost rubber isolator. Now, when you tighten this clamp down, you wanna leave it loose enough that there's still a little bit of play in the extension pipe. It's gonna make sure that your muffler and all your over axle tubes fit properly. You just wanna tighten it enough that it doesn't fall off. With our front extension pipe hung up, it's time for us to install our muffler. Now, the muffler is pretty lightweight, but it can be an awkward job by yourself so I recommend having a friend with you, if possible. If not, you can use a pole jack if you got your truck in the air or a simple floor jack if you're doing this in your driveway. You're also gonna wanna grab one of your clamps. It's a 15-millimeter bolt on the end that we're gonna tighten down. Once you secure the muffler to the front extension pipe, we're gonna go ahead and connect the two hangers on the back of the muffler to two of our rubber isolators that are on the truck still. All right, with our muffler in place, we can start installing our tailpipes. We do our passenger side tailpipe first. Gonna grab a 15-millimeter clamp, slide it over the flared end, and then you're gonna slide the tailpipe over the outlet on the right-hand side of your muffler. Next, we're gonna install our driver's side tailpipe extension using another 15-millimeter clamp. We're gonna slide the flared end of this extension on the left-hand side of our muffler outlet. Now once you hang your driver's side tailpipe extension, you don't wanna tighten down that clamp just yet. Fitment over here is very important. We wanna make sure that we can get our driver's side tailpipe hung up and level with our passenger's side using the provided isolator and the provided bracket from Borla. So, again, just hang that pipe, don't tighten it down just yet. Before we hang up our driver's side tailpipe, we have to install the provided hanger from Borla. Now, there is a hole pre-drilled in the frame of your truck that is perfectly positioned for your hanger. However, our truck did not come with any factory hardware in that location. Easy fix, we're to go ahead and use a 16-millimeter bolt with a flat washer and we're gonna use a flag nut on top of, that way we only have to tighten it down using a socket. All right, with our hanger in place, we can go ahead and slide on our driver's side tailpipe. You're gonna grab your last 15-millimeter clamp and you're also gonna grab the black rubber isolator provided by Borla. With your driver's side tailpipe hung up but still loose, you should have just enough play to move it around, get it lined up exactly where you want it, make sure it's not touching anything on the chassis or the suspension. Once you've done that and you've made sure that it's even with your passenger's side, you can go back and tighten down those two 15-millimeter clamps that we left loose. So with both of your tailpipes lined up and tightened down, go over the rest of the system. Make sure none of your pipes are, again, touching anywhere on the chassis or the suspension, that way you don't get any drone or any annoying buzzing sounds when you're driving around. Once you've verified everything's got some good clearance, you can go ahead and tighten down our original 13-millimeter clamp up here. So with that last 13-millimeter clamp tightened down, that actually wraps up my review and install of the Borla Stinger S-Type Cat-Back, fitting your '14 to '18 5.3 liter-powered Silverado or Sierra.
