      Review & Installation Video

      So, If you own a '14 to '18 5.3-Liter Powered Silverado or Sierra and you're currently looking for one of the most affordable split rear exit exhaust systems in order to really open up the sound of that motor, making sound louder and overall just better, then you should be checking out MBRP's 3-Inch Installer Series Dual Exhaust System in the Split Rear Exit Configuration.Now, at around the $500 price point, this is currently the least expensive dual cat-back available for this truck. Any exhaust systems that you might find that are less expensive than this one will either be a single exit configuration or they'll just dump underneath the truck itself or it's just gonna be a muffler replacement and you'll be cutting and clamping your factory exhaust system.Now, I'm happy to say, even though this is the least expensive dual exhaust system for this truck, it is not cheap by any means. It is made out of aluminized steel which, yes, it is an entry-level steel, it's not stainless but it's still really well built. And they do reinforce the welds on the system, so you don't have to worry about those welds rusting or corroding and cracking anytime soon. You also do get some really nice polished stainless steel tips on here. I'll show you guys a comparison but these look a lot better than the factory exhaust system. Now, sound is the most important thing. That's why we're all here, right? And I'm happy to say that this thing sounds really damn good. We're ditching that resonator on the factory tailpipe. And the MBRP Installer muffler is a lot smaller. It's a very simple baffled muffler, not a lot of chambers and crazy restrictive stuff in there, so it's really free-flowing but the important part is it gives a really nice deep idle and a really throaty sound all the way through the RPM band, as you guys probably just heard. As far as loudness goes, I'd give it a healthy three out of five on my loudness meter. I'd say this is on the limit of what would be comfortable if you daily drive your truck or if you got family or friends in there a lot, you don't want to have anything interrupting your conversation, you don't want excessive drone. Now, yes, you will hear some volume inside the cab but it's not gonna be any excessive drone that's gonna be buzzing your ears.Now, as far as the install goes, you might have to make one simple cut to the provided extension pipe, that's definitely something you can still do at home with a Sawzall or a cutoff wheel. So, I'm still giving the install a pretty soft two out three wrenches on my difficulty meter. It shouldn't take you more than two or three hours to get this installed if you've never turned any wrenches before.So again, if you're looking for one of the most affordable dual exhaust systems currently available for the 5.3 motor, then you've found it. And if you decide to pull the trigger on this exhaust kit, you could actually come back to this video in a little bit. I'll show you guys what tools you need to get this installed and then I'm gonna walk you through that install step by step. All right, guys, before we get started, we'll need a standard drive ratchet, a 5/16 Allen key or Allen head socket, a 13-millimeter socket, a 15-millimeter deep socket, and a 9/16th deep socket and wrench. Optional but helpful tools include an exhauster hanger puller tool, some spray lubricant, and an impact gun. All right. So, obviously before we install our new exhaust, we have to remove our factory one, right? And if you guys want to cut it off in sections, feel free to do so. But I'm actually gonna show you how to remove it and keep it as one piece in case you just want to hold onto it or throw it on at a later time.We're gonna be starting behind the Y-pipe in front of this crossmember right here. We're gonna disconnect our ball clamp right here just behind the resonator. In order to do that, you'll need a 13-millimeter socket. All right. Once you've loosened that ball clamp, the next step is loosening the four rubber isolators that secure the exhaust to the vehicle. There's one directly above the muffler in front of me here, there's two behind the muffler, and there's one at the tailpipe. We're gonna spray down three of those four. Then once we get to that last one on the tailpipe, I'll show you how to loosen that and I'll also show you how to remove the entire exhaust from the truck as one piece.All right. Once you get to this last rubber isolator, this is where you want to take your time. Definitely have a friend with you if you can. What you're gonna do, you're gonna spray down that last rubber isolator just behind the resonator on the tailpipe. Separate that exhaust hanger from the rubber isolator and keep a hand on the tailpipe. Gently let the over axle pipe rest on the axle itself. Once you've done that, go up front, you're gonna grab the muffler itself, you're gonna push the entire exhaust system towards the bumper, just enough to get that flex fitting that we loosened earlier over that crossmember.Once you got it over the crossmember, dip the mid-pipe down underneath, and you can pull the entire exhaust out from underneath the truck. Sounds a little bit confusing so I'm just gonna show you guys how it's done. So, before you throw the new system in place, it's a good idea to part it together, that way you can see how all the pipes are supposed to fit together, right? That's so you can also make sure you have all the hardware that you need. But while we have both systems next to each other, we can get a quick little comparison here. And yes, even though we're going from a single side exit to a dual rear exit, we don't have to drill any holes in our frame. They do provide new hardware for the new exhaust hanger. I'll show you guys how to get that bolted up in just a second. But, a couple of cool comparisons and differences to point out here. We're ditching our factory resonator on the tailpipe and obviously, our muffler is a hell of a lot smaller than our factory muffler, so that's where you're getting all that volume and tone from. Now, I did mention that this is an aluminized steel system. It's not stainless but that's not to worry. As long as you keep the undercarriage clean, you don't gotta worry about this thing developing excessive rust or corrosion anytime soon. And we do have really nice polished 409 stainless steel exhaust tips, that's a nice upgrade. Obviously, our factory system does not have an exhaust tip to speak of. Those things, they'll clean right up. You can polish those off just fine. So, where it counts, the system will continue looking good for years to come.But now that we can see how everything is supposed to fit together, let's go ahead and grab our mid-pipe. We'll go ahead and throw that in place. Before you do, make sure you double check, you don't have to make any cuts to this guy. We have a 143-1/2-inch wheelbase so we're not making any cuts. This does bolt up to that factory ball clamp. So, let's go ahead and grab that 13-millimeter socket and we'll get started. All right. So, before we throw your mid-pipe in place, you want to make sure you have this large hanger and clamp combo on there and you'll need a 15-millimeter deep socket to tighten these down. But before you do that, go ahead and spray down that rubber isolator, make it a little bit easier to get that hanger in place. You also wanna make sure that this pipe is nice and flush as far as vertically and horizontally goes before you tighten that ball clamp down. Again, you'll need that 13-millimeter socket for the factory ball clamp All right. Next, we could throw our muffler in place. You want the logo facing towards the outside of the truck on the passenger side and you also want this little support bracket facing up towards the cab and bed. And before you throw it in place, make sure you got a 3-inch clamp on there. And again, you'll need that 15-millimeter socket to tighten this down.All right. With your muffler seated, we can throw our over axle pipes in place. We're gonna start with our passenger side. Make sure you got one of those small clamps on the outlets of the muffler and again, it's helpful to spray down that rubber isolator, make it a lot easier to get that exhaust hanger in place. All right. With the over axle pipe in place, you could throw your tailpipe on. Again, make sure you got one of those clamps on there so you can tighten these things together. And for the exhaust tip itself, you'll need a 5/16 Allen key or Allen head socket. And again, it's helpful to spray down that rubber isolator, make it easier to get that hanger in place. All right. Our passenger side is all done up. Now we're ready to do our driver's side. But before we do that, we have to install our new rubber isolator and exhaust hanger. Now, there's already a hole in the frame, like I said earlier, right here next to the spare tire. So, go ahead and grab that bolt with that flat washer and you'll need a 9/16 deep socket and wrench to tighten this down. Now, we have that exhaust hanger in place, we can install our driver side pipes. Same process as the passenger side. Make sure you got clamps on everything. And you'll need that 5/16 Allen head socket or Allen key for the exhaust tip. All right. So, once you got that second exhaust tip tightened down, go ahead and double check your fitment, make sure you don't have anything rubbing anywhere underneath the cab and double check all your clamps to make sure they're nice and tight but that'll wrap up the install. And that also wraps up my review of the MBRP 3-Inch Installer Series Dual Exhaust System in the Split Rear Exit Configuration fitting your '14 to '18 5.3-Liter powered Silverado or Sierra. I'm Travis. Thanks for watching. And for all things Chevy and GMC, keep it right here at americantrucks.com.

      Description

      Stronger Sound. Blending affordability and a great exhaust note - a deep, throaty growl that grows fiercer when you hit the gas - the MBRP Installer Series 3-inch Split Rear Exit Cat-Back Exhaust features the same high-performance design as other MBRP systems, but in aluminized steel. This steel stands up to rust and corrosion for years, providing a thrifty alternative to stainless. The Installer Series cat-back, like other MBRP exhausts, shunts exhaust fumes out strongly, generating +5-10% gains in torque and horsepower. The dual pipes and single-in, dual-out muffler make the sound deeper and more aggressive than a single-out system, adding a thrilling sound boost to your 2014-2018 Silverado.

      Constructed for Endurance. Warranted for 3 years, the MBRP Installer Series Cat-Back features 3" pipes with mandrel bends at the lowest possible bend angle for superior, unrestricted flow. The part uses 16-gauge aluminized steel piping with extra aluminum silica on the seams for rust-proofing at these vulnerable areas. The tips are highly polished, rust immune T-304 stainless steel. The part features bolt-on drill-free installation and comes complete with all the necessary hardware.

      Application. The MBRP Installer Series Split Rear Exit 3 in. Cat-Back Exhaust is designed to fit on all cab and box configurations available for the 2014-2018 4.3L Silverado's.

        MBRP Dual Exhaust system

        For the money this product is great! Installed on 2015 Silverado 1500 it has a heavy drone at around 30-45mph due to V4 mode a higher end exhaust system may sound a litter better but will kinda always have that.

        Awesome and affordable!

        I decided to get this after watching Adam's review. This exhaust is probably the best bang for your buck! The exhaust has a great deep and throaty sound for guys who are looking for just a little rumble without losing the class of your truck. My only issue with it is that when your truck goes into V4 mode around 70MPH, it starts to sound a little funky. However overall, the sound is great! Install wasn't that difficult for someone without too much mechanical knowledge. The most difficult part was getting the old exhaust out over the axles. I ended up cutting it out with a sawzall. Thanks American Trucks!

        MBRP dual exhaust

        Opened the package and everything was included to install the exhaust. All the pipe ends fit well together, just slid them in and clamped em down! The tips lined up pretty well when I was done, just had to wiggle here and there to make it look sweet! Truck sounds like a truck now!

        MBRP Exhaust Install

        The system came complete with all fasteners, clamps. The install went well, until I reached the driverside rear hanger bracket (supplied). when the system was completely installed , I noticed that the drivers tailpipe was hanging 3 inches lower than the passengers. I had to spacer the bolt on bracket up inside the frame rail to make the difference. Looks good, sounds awesome, overall happy. J Carter Texas
