      Review & Installation Video

      So, MBRP's 3-inch XP Series Single Exhaust System is currently one of the most affordable factory style exhaust upgrades if you own a '14 to '18 5.3-liter powered Silverado. Now, as the name implies, you should be checking this thing out if you want something that's going to be nice and loud with a good, deep tone to it, but you like the look and feel of that factory exhaust system.And that's a great thing because at around the $500 price point, this is currently the least expensive stainless steel exhaust available. Anything that's gonna cost less than this one will be made out of aluminized steel and aluminized steel will show signs of rust and corrosion a little bit quicker. Now, 409 stainless is awesome, that's factory grade. That's the same stuff that the original exhaust system is made out of. And I'll show you guys how that can stand up to the test of time in a little bit when we do a side-by-side comparison of the original one and the new one. But what's even nicer on this system is the 304 stainless tip.304 is pretty much the best stuff you can buy so you get the good looks where it counts. You can polish this thing up. Even if you see a lot of snow or rain, you don't gotta worry about that rust or corrosion anytime soon. Now, as far as volume goes, this gets a healthy three out of five on my loudness meter. It definitely wakes up the sound of the 5.3 motor, but it doesn't go overboard.And there's also no drone inside the cab, which is awesome if you have passengers, you want to keep a conversation, or you daily drive your truck and you don't want to have that kind of head buzzing every morning on the way to work, right? Now, even though this is a healthy three out of five, it still sounds really deep and throaty. There's no raspy back pressure pops or crackles or anything like that. You get a really old-school lopey idle and everything stays nice and deep all the way through the RPM band so you get that nice deep tone, no matter what gear you're in.Now, as far as the install goes, there might be some cutting required, but if you have the right cab and bed length, it is a bolt-on kit. If you do have to make that cut, it's very simple, you can definitely do it at home. So, for that reason, I'm gonna give the install a two out of three wrenches on my difficulty meter. Shouldn't take you more than two or three hours to get this thing bolted up.All right, guys. To install your MBRP kit, you will need a standard drive ratchet, a 5/16 Allen key or Allen head socket, as well as 13 and 15-millimeter deep sockets. Now, optional but very helpful tools include an exhaust hanger puller tool, some spray lubricant, and an impact gun. All right. So, there are two generally accepted ways to remove your factory exhaust. You could go the fast and easy route and cut everything off, but there's also a way to retain your factory exhaust as one piece. I'm a fan of keeping my factory components whenever possible, so, I'm actually gonna show you guys how to unbolt this thing and get it removed without cutting.Now, we're gonna start up here behind our Y-pipe. We're gonna remove the clamp securing our factory cat-back. In order to do that, you'll need a 13-millimeter socket. All right. Once you got that clamp removed, we're gonna start pulling the rubber isolators that secure the exhaust hangers of our factory cat-back. Now, there are a couple here. You got one directly above me here behind this crossmember, you got two behind the muffler, and then you got one at the tailpipe.Now, if you're doing this by yourself, like me, it's helpful to have the exhaust supported by pole jacks or jack stands. But if you have a friend with you, that's helpful too, just make sure he or she is holding onto the tailpipe when you pull that last rubber isolator. It's also very helpful to have an exhaust hanger puller tool or some sort of pry tool like me, and it's also very helpful to have some spray lubricant. We're gonna spray down all these rubber isolators. We're gonna remove them from all the exhaust hangers, then we're gonna lower down our cat-back over the axle.We're gonna push everything back towards the rear of the bumper so that the flex fitting can go over this crossmember. Once that's dipped down, we can pull the entire exhaust out from underneath the truck. All right. So, with that last rubber isolator removed from our tailpipe here, you can see our exhaust is now technically free from the vehicle. It's only supported by the pole jack behind me or if you're working with a buddy, in that case, it'd be your friend. So, what we're gonna do, we're gonna lower this thing down. We're gonna let the over axle pipe rest on the axle.Again, we're gonna push everything back towards the bumper so we can get that flex fitting over the crossmember, then we can pull the entire system out from underneath the truck as one piece. All right. We have our factory cat-back removed so you can hold onto it if you please. But before we throw our new XP Series system on, we want to mock everything up, that way you guys can see where everything is supposed to go and you can see a nice comparison, some of the differences between the two and obviously the big star of the show here is the XP Series muffler. It's a much simpler and much more free-flowing muffler and that's where you're gonna get that extra volume from. Now, as far as the tone, the system's a lot deeper sounding and I love that personally and that's because we're stepping up our flow tube diameter from 2-3/4 inches up to 3 inches.We're also ditching that factory resonator there on the over axle pipe, it's gonna open up the exhaust even more. So, overall, better tone and volume, right. Now, Chevy kind of missed the mark on the factory tailpipe there. There's no tip to speak up. So, MBRP did us a solid, they throw in a really nice polished 304 stainless steel tip by the way. That thing will clean up nicely for years to come and you don't gotta worry about rust or corrosion eating that thing out anytime soon.Now we are working with 143-1/2 inch wheelbase truck, so we do not have to cut our mid-pipe. Just keep in mind if you had a different size truck or a different size cab and bed length, you will have to make one cut to this thing, but we don't have to do that today. So, now that we can see these nice comparisons here, we see how this thing supposed to go together, let's go ahead and throw it on the truck. We're gonna start with our mid-pipe. We are reusing that factory clamp on the Y-pipe, so go ahead and grab that 13-millimeter socket and wrench and let's get started.So, like I said, we don't have to make any cuts to our mid-pipe so we can just throw it in place. And again, you're gonna to be using a 13-millimeter socket to tighten down that factory clamp. But before you throw this in place, you wanna grab this hanger and clamp combo kit, because that's actually gonna be seated in that first rubber isolator that we removed earlier.Now, when you tighten this stuff down, you want it tight enough that this pipe's not going to go anywhere, but you want a little bit of free play in there. It's gonna make it a lot easier when we get our muffler in place, as well as all of our over axle pipes and our tailpipe. All right. Now we're gonna level out this hanger and thus level out this mid-pipe. Once you get this relatively level, you're gonna tighten this down with a 15-millimeter socket. All right. With our mid-pipe in place, we can throw our muffler on. Before you throw the muffler on the mid-pipe, make sure you got a clamp on there so you can secure them.Now, you want the MBRP logo facing towards the outside of the truck. All right. With our muffler in place, we're gonna hang everything up using our over axle pipe. Make sure you spray down both of those rubber isolators, make it a lot easier on yourself, and of course, as you can see behind me, make sure you got a clamp on the outlet of the muffler so you can tighten it down once you got this in place.All right. With our over axle pipe in place, you could throw your tailpipe on and your exhaust tip. Again, before you throw the tailpipe on, make sure you got a clamp on the end of that over axle pipe, and then once you get the exhaust tip in place, verify everything is lined up and you're happy with where the exhaust sits. Once you've done that, you can tighten down the exhaust tip using a 5/16 Allen key or Allen head socket, Once you got your exhaust tip tightened down, go ahead and double check your fitment of the entire exhaust system. Make sure nothing's rubbing anywhere, then you can drive all those clamps home. Remember, in the beginning, we only tightened down that first clamp just enough to keep that pipe in place. We got to make sure that we don't have any leaks back there. So again, just double check all your clamps with your 15-millimeter socket. Use that 13-millimeter socket up front and that'll wrap up the install. All right. So, once you got all those clamps tightened down, that'll wrap up the install. And that also wraps up my overview of MBRP's XP Series Single Exhaust System in the factory Side Exit Configuration fitting your '14 to '18 5.3-liter powered Silverado. I'm Travis.

      Description

      Stronger Performance. Aiming squarely at both solid power gains and robust long-term durability, the high quality MBRP XP Series Single Side Exit 3-inch Cat-Back Exhaust brings improvements you can use and enjoy every day to your 2014-2018 Silverado. See gains in both horsepower and torque, alongside a boost in fuel efficiency. Sweeping away stifling backpressure and making space for cold air to rush into the engine, the cat-back also cuts down on the hazard of engine breakdown and keeps lubricants fresher. It also changes the exhaust tone to a smooth but authoritative rumble.

      Heavy-Duty Engineering. Mandrel-bent tubing and a high-flow muffler provide the core features of the MBRP XP Series 3-inch Cat-Back, ensuring strong exhaust flow. T-409 stainless steel ensure permanent rust-proofing and corrosion protection, though the metal will change color slightly unlike T-304 stainless. The 4” tip is T-304, however, so that it will always keep its brilliant mirror sheen and silver color. This part has a lifetime warranty and is made for bolt-on, weld-free fitment. Depending on your cab and box configuration, some cutting to the piping may be required.

      Application. This MBRP XP Series Single Side Exit 3-inch Cat-Back Exhaust is designed to fit on all cab and box configurations available for the 2014-2018 5.3L Chevrolet Silverado 1500 models with an one-piece driveshaft.

        Exhaust

        Over all, a very clean upgrade. It is not a straight-up install. It required some minor modifications. I typically install all mods on my vehicles. In this case I was happy to go to a muffler shop for this install. Sound is good but not intrusive in the cab. Increase in mileage is marginal. I am hoping that a good cold-air intake along with a free-flowing exhaust will facilitate better fuel economy.

        Great Exhaust for the Money

        Install took around 45 min. The only thing that took a little time was getting the oem system out of the way because I didnt use a lift or jacks. Easy install. Great tone. Overall very pleased with the system.

        Excellent cat back for Silverado's!

        "For reference, my truck is actually a 2019 Silverado LD (old body style) 5.3 4x4 LT which is not listed in the vehicle selection dropdown" My assessment of the MBRP exhaust which I just had installed this morning: I took the truck out for a drive and did some city and highway driving. On startup it sounds great, acceleration sounds loud up until you get to cruising speed. I drove it at 70 and you can just slightly hear the exhaust at that point, No drone! (I have an AFM disabler installed) I wanted something louder but not to loud and this exhaust does just that. To compare I heard the Carven and it had to much like a high pitch sports car sound. I liked the Borla also but the Atak was too loud and the S-type didn't sound much louder than the touring. The MBRP XP seemed like the perfect compromise. It's loud enough only when you need it and it's has a nice deep sound which properly matches the truck. It sounds to me alot like something between a Flowmaster and Magnaflow. When I drive it now feels like the engine has been liberated. You can feel that it's less restricted! I took my wife with me and she was happy with the results as well. She was concerned for when we take road trips. As for quality, it seems very well made and came in a box where everything was packaged tight and intact. All in all I'm very happy with it and feel that it was money well spent.

        Good quality product especially for the price compared to other brands. Very easy to install. It does have some droning in the cab especially when it goes into V4 mode.

        Great sound , just what I was looking for. I did have to cut about an 1-1/2" off one of the pipes because the hanger was against the shock.
