So if you own a '14 to '18 Silverado or Sierra and you're looking for the absolute loudest possible and one of the most well-built exhaust systems currently available for this truck, you should be checking out Borla's ATAK dual exhaust system with the split rear exit configuration and these very cool and very unique black chrome tips. As you just heard from our sound clips, this thing easily gets a five out of five on my loudness meter. It quite literally will wake your neighbors in the morning.Now, besides the fact that this thing is one of the loudest available options, it's also one of the best sounding in my personal opinion and that's all thanks to ATAK muffler. If you're curious what ATAK stands for it, well, here it is. It's acoustically tuned applied kinetics. That's Borla's fancy way of saying that they basically designed the muffler to eliminate any drone or raspy notes. So, all the way from idle to redline, the system just sounds really good overall. Besides that, there's other reasons why this is one of the most well-built systems. One of those primary reasons is the fact that it's made out of 304 stainless from end-to-end. 304 stainless is considered the best steel in the category. It's better than the factory-grade 409 and it's certainly better than aluminized steel. So if you take your truck off-road or you see a lot of rain or snow, you won't ever have to worry about the system rusting out on you.Besides that, I actually really like the black chrome tips. It's certainly a unique look. Now, if you wanted to go with standard polished chrome tips, you could pick those up for about $100 less. Now the last primary reason why I like the ATAK system a lot is besides the fact that it's the loudest and the most well-built, it also installs very easily. Borla's quality control is pretty much second to none. Everything's mandrel bent to fit just fine and this system doesn't actually require any cutting because it's pre-sized for your cab and your bed length. So it is a bolt-on system.So I'm gonna go ahead and give the install a very easy one out of three wrenches on our difficulty meter, should be able to get this done at home in the driveway in about an hour or two. So if you really like the ATAK system and you wanna pull the trigger on it, go ahead and stick around. I'm actually gonna show you guys the install step-by-step.To install your Borla cat-back, you'll need the following tools: a standard Drive Ratchet, a 13-millimeter socket, and a 15-millimeter deep socket. Optional but helpful tools include a pry bar or an exhaust hanger puller tool, as well as a cordless impact, and some spray lubricant.So our factory cat-back can actually be removed as one piece. Sounds complicated, it's actually pretty simple. You just have to loosen one clamp up here in front of the crossmember just behind the Y-pipe and the catalytic converter itself. To loosen that clamp, you're gonna need a 13-millimeter socket. Now that that clamp has been loosened, we can pull our factory cat-back from its rubber isolators. There are four in total, one directly behind the crossmember, two behind the muffler, and one at the tailpipe. Pulling these can be a little bit difficult because it is metal on rubber so it's helpful to have some spray lubricant and you'll either want a pry tool or an exhaust hanger puller tool.So once you get to that last rubber isolator on the tailpipe, and you pull this one out of here, your exhaust will be free from the truck. Now the exhaust is a little heavy, so you wanna take your time when you do this. Best approach is to let the over-axle portion of the tailpipe rest on top of the axle. Just let it down gently, that way you're not crushing anything back here. Once you've done that, go back up towards the front of the exhaust and push everything back towards the rear bumper. That should give you just enough space to get that flex fitting over your crossmember up there. Once that flex fitting has passed the crossmember and dropped down, you can actually remove the entire exhaust from the vehicle as one piece.So now we have our factory cat-back removed, we went ahead and we mocked up our new cat-back. That way we can see where everything is supposed to go. And while we're here, I can answer some questions that you might have had. First things first, you can see the 304 stainless on this is much higher quality than our factor 409 stainless. Our truck has seen some weather. It's got some miles on it, and 409 can kind of start to show some surface rust and corrosion. 304 stainless does a lot better job of holding up to the elements. So if you daily your truck or you take it off-road, you won't ever have to really worry about that stuff. Other thing that I really like about this setup is the fact that the muffler and the mid-pipe are already set for your cab and bed length. So again, there's no cutting required. That makes this system purely a bolt-on system.Other cool differences and similarities here, I really like that this thing reuses all the factory hanger locations so you don't have to cut or do anything with your frame or the body itself in order to get this thing installed. Yes, we are going from a single exit to a dual exit. Borla's nice enough to throw in a new hanger and there is already a pre-drilled hole in your frame. I'll show you guys where that goes in a little bit. Last thing to point out, I really love the fact that Borla welded the exhaust tips onto the tailpipes. With modular setups like this, where it's a bolt on piece by piece, it can be a bit of a hassle getting those things lined up and squared off, but in this case, it's already done for you. So once you bolt this thing up, it should look pretty much perfect from the get-go. Now you can see how this thing is supposed to sit once it's installed. Let's go ahead and start throwing it on our truck. So the first step of our install is putting on our new mid-pipe. First things first, you wanna throw your new hanger into your original rubber isolator just behind the crossmember. Once you've done that, go ahead and line up the flared end of the mid-pipe with the original clamp back here. Once that's all lined up, you wanna tighten down this clamp just enough to keep the pipe in place. You wanna have a little bit of free play, that way we can make sure we get everything lined up before we tighten everything down.Now that we have our mid-pipe in place, we can install our muffler. Before you throw the muffler on the mid-pipe, make sure you have the largest clamp in the kit on there that we can tighten this down later. Once you got the flared end of the muffler on the mid-pipe, you wanna put your hangers and your factory rubber isolators just above your axle.So, now that we have our muffler hung up, we can install our passenger side tailpipe with our exhaust tip. You wanna make sure you get the flared end of the tailpipe into the outlet on the muffler. You're gonna put the hanger into the original factory rubber isolator that was holding your original tailpipe in place. Before you throw this up there, you want to make sure you have one of the clamps on the pipe so you can tighten it down later.So now that our passenger side is all set up, we can start installing our driver side tailpipes. But before we do that, we're gonna install the hanger that Borla provided that I mentioned earlier. Again, there is a pre-drilled hole up here in the frame so all I gotta do is line the hanger up with your hardware and tighten it down. All right. So, now that we have that hanger in place, we can start installing our pipes for our driver side. We're gonna start with our over-axle pipe. And before you throw this on the muffler, make sure you have a clamp on the outlet of the muffler so you can tighten down this later.Once you got your over-axle pipe in place, you can install the driver's side tailpipe. It's the same process as the passenger side. Make sure you get the flared end into the over-axle pipe, make sure you got that last clamp on there so you can tighten it down, and go ahead and throw your hanger into the rubber isolator that we just installed. Once you've got this installed, make sure everything's lined up. Then we can tighten down all our clamps. For Borla's clamps, you'll need a 15-millimeter socket. And then once we're done tightening the cat-back down, make sure you go back up front behind the catalytic converter and tighten down that 13-millimeter clamp.So once you got that last clamp tightened down, that should actually wrap up our install. And that also wraps up my review of the Borla ATAK dual exhaust system with the split rear exit system and the very cool black chrome tips fitting your '14 to '18 at 5.3 liter powered Silverado or Sierra.

Perfect! Borla Atak for Silverado 5.3
Stop thinking about it! - and skip to the end, and buy it. If not, keep reading: After much research and debate between the Borla - Touring - S Type - Atak, and other brands, I chose to go with the Borla Atak. I read many reviews saying how they regret not buying the Atak, and other saying that the Atak is too loud and should be illegal. Well, it should be illegal, because it's freakin' awesome!This is how a truck should sound, especially if you have a lift. I am more on the conservative side when it comes to how loud cars tend to be, and would get annoyed over obnoxious loud cars, it is annoying. This is different. It is very loud on cold start, a bit too much, but it lasts a few seconds, then quickly dies down. After that at idle, you can hear a deep rumble, but not loud. At cruising speeds, I can hear my size 35 tires over the exhaust, but it's not until when I press down on the gas when you hear the deep rumble, just perfect sound when you truly need it or want it. Install is easy, make sure you have all the right tools before you begin, definitely recommend the Lisle Exhaust Hanger Removal Pliers, it will save you tons of time. It is expensive, but the quality you get is very good, and satisfaction is immediate. The rear exit, black chrome was perfect for my truck Good luck!Helpful (1)

Great Exhaust but one problem
Exhaust sounds awesome and the more miles you put on it the ATAK will break in and bring out more deep throaty sounds. One thing I noticed is during left hand turning I get a loud grinding sound. The hook on the left side that you put your supplied isolator on is about a half inch longer than factory causing it to rub on the frame and cause a grinding sound. It got so bad I thought something was maybe wrong with my suspension. Took my 17 Silverado into the Chevy dealership and they did some minor shaving of that left hanger and I’ve had no issues at all with grinding anymore. It cost me $69 from Chevy to repair. That being said I still love the exhaust and don’t regret my decision on purchasing one but. It’s nothing that will cause issues to your truck but more annoying if you don’t get it fixed. I recommend this to anyone!! Seriously Turns heads everywhere I go. My neighbors LOVE meHelpful (1)

Best money spent
Exhaust is plug and play easy install. Hardest part was getting the old one off.Helpful (8)
Why is this exhaust not available for standard bed!!!?
Due to the different wheelbases of the trucks, this exhaust is only going to work for the Double Cab with the Standard Box and the Crew Cab with the Short Box.
What size cut outs should I buy for this exhaust 3in?
Cutouts that would match the diameter of the system would be the best fit.
Will adding this exhaust void warranty?
We cannot comment on what would or would not void the warranty as it seems to be different depending on the dealership you speak with. We would recommend speaking with your dealership to make sure you'll be good to go.
Is there something you guys sell like an extension of some kind to fit this to a crew cab standard box?
Unfortunately, we do not carry an extension piece to make this fit a crew cab standard box.
