So, if you're looking for one of the best sounding exhausts available for the '14 to '18 5.3-liter Silverado or Sierra, I think you should be checking out Magnaflow's MF Series Black Cat-back with the rear side exit configuration. In my humble opinion, this is one of the best sounding and most well-built cat-backs available for the '14 to '18, and that's for a couple of reasons. In terms of sound, it gets a healthy three out of five on my loudness meter and when other systems get this loud, they tend to sound raspy or gurgly. That's not the case here. Thanks to the MF Series muffler on this kit, this is one of the deepest and cleanest sounding systems in my opinion. Now, the other reason why I really like the MF cat-back is because of the build quality. You're getting factory grade 409 stainless which is excellent if you daily your truck. But what's really nice about this system is that you have this high temp black coating on here. That's really great if you're doing a blackout build or you want something subtle. But on top of that, it's actually gonna protect the steel underneath which is excellent if you live on the East or the West Coast, you daily your truck like I said, you go through a lot of rain or mud, you take your truck off-road or whatever. It's gonna protect it better than any other coating currently available for any of the other exhausts on the page. Now, if you like the way this system sounds, stick around. There's no cutting or drilling required for the install so it gets a very easy one out of three wrenches on my patented difficulty meter. You actually should be able to get this done at home in the driveway with basic hand tools. Shouldn't take you more than an hour or two. So, without further ado, let's go ahead and get started. To install your Magnaflow cat-back, you'll need the following tools: a 13-millimeter deep socket, a 15-millimeter deep socket, a 3/8 drive ratchet, two 11/16th wrenches, and optional but helpful tools include some spray lubricant or PB B'laster, an impact wrench, and a pry bar. So, before we install our new cat-back, we have to remove our factory cat-back. Lucky for us, it actually comes off as one piece. Now, to uninstall it from the truck, you have to pull one of these clamps here directly behind the cat and that's gonna be a 13-millimeter head bolt. Now, that we have that clamp loosened, we have to pull the exhaust using a pry bar or you can use an exhaust hanger puller tool. There are four rubber isolators, one up here in front of the muffler and three behind the muffler. It's also helpful to have some spray lubricant handy. That will help those rubber isolators loosen up a little bit. All right. So, with those two rubbers isolators removed directly behind the muffler, you have one more here near the tailpipe. That's holding the cat-back to the vehicle. Everything else is disconnected so, when you pull this last rubber isolator, you wanna watch your head and your hands to make sure this thing doesn't come down on you. You're gonna let this thing rest on the axle and then, once you have your entire cat-back resting, you're gonna push it back towards your rear bumper and you're gonna pull the entire assembly out as one piece. So, now that we have our factory exhaust removed, it's a good idea to mock-up the new cat-back, that way you can be totally sure of where everything's actually gonna install. Now, first things first, you can see that this reuses all the factory hanger location and rubber isolators so you don't have to actually modify your truck or do any cutting or drilling to install the new system. It bolts up exactly in the same fashion as the factory exhaust. And on that note, you are gonna be reusing that 13-millimeter clamp up here just behind Y-pipe. Moving on down the line, you can see the MF Series muffler is way smaller and more compact than the factory box which is primarily responsible for giving you that nice increase in volume and sound. And then, as we move down here, over the over axle pipe, you can see we ditched the factory resonator in favor of some nice free-flowing mandrel bent tubing, and then we end with these awesome 4-inch double wall black tips. So, without further ado, let's go ahead and throw this system on our truck. So, installing our new cat-back starts with the front extension pipe. You're gonna feed the flared end into the Y-pipe behind the cat where you loosened that 13-millimeter clamp and you're gonna make sure that you thread the new hanger into that first rubber isolator as you do so. Now that our front extension pipe is hung up, it's time for us to install our muffler. Now, to do that, you're gonna need to grab the largest clamp in the kit and throw it on the back end of the front extension pipe and then the flared end on the inlet of the muffler is gonna feed into there. Now, it's a good idea to have a friend with you so they can hold the muffler in place because it is a little heavy. I'm working by myself today, so I actually have a pole jack here to help me keep it in place. All right. Now, that our muffler is hung up, we're gonna install our over axle pipes. To do that, we're gonna take two of the small clamps provided in the kit. We're gonna throw one on each of the outlets on the muffler. Then, we're gonna start with the first half of each over axle pipe. All right. With your over axle pipes hung up, you wanna keep those loose. You don't wanna tighten them down just yet because we wanna play around fitment, that way we can make sure that none of the tubes are clanking against the truck and that way we can make sure that the actual exhaust tips exit on either side and they're even. Now, we're gonna grab the last of the tailpipes and install those. You're gonna grab one of the small clamps provided in the kit for the passenger's side. All right. With our passenger's side tailpipe hung up but still loose so we can play around with fitment, we're gonna install our passenger's side exhaust tip. You're gonna grab, again, one of these small clamps in the kit to secure this. All right. With your passenger's side tailpipe and all your clamps in place, it's time to play around with the fitment. Go ahead and make sure that the tip is not rubbing against the body up here. And then, once you're happy with everything and where it's sitting, you can tighten down all the clamps on this side. For that, you're gonna need a 15-millimeter deep socket. Now, before we finish installing our driver's side, we have to install the provided hanger. To install the hanger, you're gonna need two 11/16th wrenches for both of the nuts on here. All right. With our new hanger and isolator in place, it's time for us to finish installing the driver's side. To do that, you're gonna grab your tailpipe and you're gonna grab the last of the small clamps and throw it on the flared end like so. All right. With our driver's side tailpipe installed, the last step here is throwing on our driver's side exhaust tip. To do that, you're gonna grab the last of the large clamps in the kit. Go ahead and throw it on the end here. Once you've done so, same thing as the passenger's side. Line everything up. Once you're happy with where everything is located, we're gonna go back to front and tighten down all the clamps up to the muffler. All right. With everything behind the muffler tightened down, the last step is making sure everything in front of the muffler is tight as well. You got one last clamp up here. This is the 15-millimeter bolt head and the one on the Y-pipe/cat is that 13-millimeter factory bolt head. That actually wraps up my review and install of the MF Series cat-back available with the side exit configuration. I'm Travis. Thanks for watching. Keep it right here at americantrucks.com.
