      Review & Installation Video

      Hey, guys. Adam here with americantrucks.com. Today we're taking a closer look at and installing the Magnaflow Street Series Black Cat-back exhaust with the split or dual rear exit available for the '14 to '18 5.3 Silverado 1500. Now as you just heard from our sound clip, this guy isn't gonna be a huge change from your factory exhaust. This is gonna get two out of five on our loudness meter here but there are a couple of big changes. Mainly, appearance and materials. Now focusing in on the sound there, that two out of five is really gonna give you a smooth, slightly deeper exhaust note and I actually think that it is a really rich tone. Inside the truck you'll hear a lot more engine noise than you hear exhaust so you don't have to worry about any drone whatsoever even at highway speeds but outside the truck, especially at, you know, light to light cruising speeds during your daily commute you'll have a little rumble at the back end but nothing too major. So if you're not looking to go overboard with something too aggressive or too loud, this is really a nice mellow option. Now if you like the Magnaflow quality and the Magnaflow brand, there are a number of other options from them in their series. Now not only can you get the Street Series here in the dual rear exit, you can get a dual side exit, middle side exit, dual split exit and you can get the turndown style. Now that pretty much dumps right after the muffler right into the center of the truck. Now if you're not really feeling the Street and you want something a little bit more aggressive, they have their Competition option which is gonna beef up that sound somewhere around three, maybe four out of five on the loudness meter. If you're really looking to beef things up, you can get their Off-Road Series which is essentially just a straight pipe. So a number of options. They really have everything for any of your personal preference and you can get that in category.The big appearance change here is very apparent. Now the factory exhaust has that side exit right behind your rear passenger tire. This is gonna split off into a dual exit going right toward the rear. Now this rear exit actually has a black finish on everything after the muffler going back to the tips. That's gonna help beef up that corrosion and rust resistance while also giving you a nice, stealthy finish at the rear. So if you're looking for a more muscle car look for your truck, the dual exit works and the stealthy black adds to it.Now the materials are an upgrade over factory as well with 409 mandrel bent stainless steel. 409 is gonna be that middle of the road materials between aluminized being the more affordable option and 304 being the top quality in the category. So if you're looking to last a little bit longer on your truck, especially if you're located in wintery weather areas seeing road salt, this is gonna be a better way to go, especially with the black compounding, that protection.If you're looking to spend more money on the most premium, some 304 options are gonna be the way to go. Now this kit comes in right around 1,100 bucks, 1,150 bucks making it not necessarily the entry level kit but it's not the most expensive either. Again, falls right in the middle of the pack.Now, the install I'm gonna give two out of three wrenches on our difficulty meter. It's very simple. You can do it in your driveway at home. Makes it a lot easier if your truck is lifted six inches like ours is and I'm gonna show you every single step of the process. It'll take two, maybe three hours from start to finish. No drilling required and no cutting. So let's get to it.Tools used in this install include an impact gun or a ratchet, 15 and 13 millimeter deep sockets. I used two 3/4 wrenches. One is a ratcheting wrench which I think makes life a lot easier but a basic wrench will do the trick as well. Hanger removal tool goes a long way and WD-40 or PB B'laster or something similar.First up of the uninstall here of course get your truck up in the air and properly support it either on jack stands or on a lift like we have it here. I have pole jacks supporting it at the end and the middle of the exhaust so when we start unbolting it, we have some support. Grab your 13 millimeter socket. We're gonna loosen up this bolt holding the clamp next to our catalytic converter.All right. Next step. We're gonna grab our hanger removal tool and we're gonna pop out our hangers from our isolators. Now it's a good idea to grab WD-40 or PB B'laster or something similar to lubricate both sides of this to make life easier. There's a couple of these we'll have to remove along the exhaust. A hanger removal tool is definitely gonna come in handy here.Now on the side of our muffler closest to the rear of the vehicle we have two hangers and you can see I have my pole jack here because once these two come off, this is gonna start to drop down a little bit and we want that support there. I'm gonna grab my hanger tool and pop these guys off.Last hanger before the entire exhaust is free in one piece is right above our tailpipe. And there you have it. Now we can grab a helping hand or if you can do this yourself, you can pull the whole exhaust off in one piece.So we got our factory exhaust off of our 5.3 Silverado and it's on the ground here next to our dual exhaust from Magnaflow. Now I wanna take you through some similarities and differences between the two kits and I wanna start up front. Now going from here to the muffler everything is relatively similar. The only big difference here is gonna be the materials and the diameter of the tubing. So we're going from the factory steel over to our new 409 stainless steel with mandrel bends which is gonna help make it kink-free with less restriction. Three inch diameter is a little bit bigger than our factory 2.75 inch and that is gonna move all the way down to your muffler. Now the factory muffler here is obviously about twice if not three times the size of our Magnaflow option and it's got a lot more baffling in there to minimize that sound while it is minimizing a lot of drone as well but it's not as aggressive as you'd like your Silverado to be. The Magnaflow option here is a straight through muffler so it's gonna produce that sound that you heard earlier in our sound clip.Moving forward from there you'll see instead of the factory common traditional single exhaust that dumps out behind the rear passenger tire, this is gonna split off into a dual exhaust with a rear exit. There's a couple of different unique characteristics here. Number one, the dual exhaust is obviously very different. It's gonna split off from the 3 inch to a dual 2 and a half inch tubing. So the dual 2 and a half inch tubing is mandrel bent going back to twin slash cut 4 inch black tips. Everything from here back is gonna have a high temp satin black finish. That's gonna add durability to the exhaust materials and you really want that durability here from the muffler back to the tips so it doesn't corrode as easily. 409 stainless is that middle of the road material so 304 is the most durable. Adding the black finish here is gonna beef up that 409. It's also gonna look pretty good. If you're not really into the chrome or polished finish in your tips, having the black option is gonna make it a lot stealthier.The only other thing to mention here is that on your tailpipes from the factory you have this resonator, not gonna be the case on your Magnaflow so it is gonna have a little bit more of a raspy pitch to it. You might even get a little bit of interior drone but at the end of the day, it's a lot more aggressive. Now we're gonna kick off the install starting at our extension pipe here with our flex pipe. So what do you say we get started?First up here, grab your pipe that has this flex tube on it. We're gonna feed this over top of our sub frame, connect it to our catalytic converter, but first we wanna make sure that we're putting it inside our isolator here. So let's start feeding it over. I'm gonna push this hanger into the isolator. Now we can connect our flange.All right, so what we're gonna do is make sure these are seated completely up against each other. Grab that factory ball clamp. And we're gonna tighten this down. Now I'm gonna get it nice and snug, still leaving a little room for adjustment. We'll come back later and tighten it down.All right, so next up we're gonna take our muffler that has another pipe attached to it and it has two hangers. What we're gonna do is slide the pipe into the pipe we already installed and then focus on our hangers. Make sure you have a clamp on the inlet.All right, so we have that inserted. Now we can bring this up and connect it to the hangers. Perfect. Now you can grab a 15 socket and we're gonna get this clamp nice and snug. Now we're not gonna tighten it down too much. Like I said earlier, leave a little bit of room for adjustment and we'll come back later.All right, so now we can grab the shorter S shaped pipe. We're gonna start on our passenger side because the hanger is already in place from the factory exhaust. Make sure you have one of the smaller clamps. Feed this guy over the axle. We're gonna make sure it's facing upward and we're gonna attach it to the outlet on our muffler. All right, so now we can get this clamp snug.To closely finish out our passenger side, we're gonna put our tailpipe into place before our tip. You wanna make sure again you have another clamp in place. We're gonna connect this to the pipe that we just put over our axle. But before we tighten that down, we're gonna insert it into the factory hanger. All right, so we've got that in there. So we're just gonna push the exhaust back a little bit and swing this hanger into place and slide it in. of course using WD-40 goes a long way and can make life a lot easier. All right, so rotate your clamp upward and tighten it down.All right, next up we're gonna take our driver side pipe that'll connect to our muffler outlet and this guy has almost a 90 degree bend on it. We're gonna feed this over the axle with the clamp on the inlet side and connect it to our muffler. You wanna make sure you're feeding it right around your spare tire. All right, so once you have that seated all the way down, grab your 15 socket and tighten down that clamp.Now obviously our factory exhaust wasn't a dual so we don't have a stock hanger on our driver side so we're gonna install one included in the kit from Magnaflow. You'll basically get a hanger with a threaded stud, two washers, two nuts and the isolator. I have the isolator on already. Again, WD-40 goes a long way to help you out there. What you're gonna do is basically set up a jam nut collar. So you have one nut upside down, threaded down I'd say about 2/3 of the way down. I'm gonna put one of the larger spacers in and now we're gonna thread this up through the hole in the frame. You'll see right in the middle there's a larger hole with a smaller one on the right and a smaller one on the left. You're going right into this big guy. You're gonna put that up through. You're gonna drop a washer in on the top of the stud above and then thread the nut on the top as well. You wanna make sure you're centered right on over that hole so it's completely covered by the washer. Now once you have the position correct, and you can adjust it up or down by loosening these and bringing the stud down, once you have it exactly where you want it, you can tighten them down with two wrenches.All right, so at this point I have a ratcheting wrench up above on top of the stud hooked onto our nut on top and I also have another wrench right here. So the top one, I'm just gonna hold in place and this guy, I'm actually gonna tighten down. All right, and there we go. Putting that guy back into place.Now we can take our driver side tailpipe and we're gonna attach that, the over axle next to our spare tire and then insert it into that hanger we just installed. Perfect. Now you can feed this clamp up and tighten it down right next to the spare tire.Last but not least, let's install our tips. So we have one of our clamps inserted over the tip inlet. I'm gonna slide this guy all the way in. Align it where you want and then tighten down the clamp. All right. Now do this exact same thing for the other side. Now you can go back, make any adjustments you need to and tighten down all your clamps.That's gonna wrap up my review and install for the Magnaflow Street Series Cat-back with the Dual Rear Exit in black available for the '14 to '18 Silverado 1500 with the 5.3.

        Magnaflow exhaust

        Looks great sounds great. Install was a little tough without a lift getting the old exhaust out from underneath because everything was welded together from the factory from cat back. Install was pretty easy. The driver side pipes were put all the way inside the other pipes but passenger side was all only put halfway in the pipes so that the final length matched. Seems like passenger side pipes could of been a little bit longer. But it still worked out.
