Hey, guys. Adam here with americantrucks.com. And today, we're taking a closer look at, installing and listening to the Pypes Violator Dual Rear Exit Exhaust System for the 2007 to 2017 5.3 Silverado 1500s. You should be checking this out for your own Silverado if you're looking to ditch the factory exhaust to beef up the sound and give you a more aggressive appearance with your truck.We all know the factory exhaust on the 5.3 leaves a lot to be desired, so swapping out for a cat-back is definitely on most people's minds. Now as you just heard from our sound clips here, the Pypes Violator is gonna get three out of five on our loudness meter, it's not too loud but it's also not too quiet. It's that perfect middle ground, great for the daily driver who just wants to, you know, be a little bit more aggressive and be heard.At wide-open throttle, of course, this thing is gonna bark, it's gonna let everybody know it's aftermarket. But at idle, it's got a nice deep, pretty mellow rumble. Driving speed, red light is a red light, guys, it's gonna have a nice rumble, it's gonna have a nice little sound, little bark. Again, not too aggressive, not too overwhelming.The Violator muffler included in the kit that we'll break down a little bit later on is gonna be something that doesn't have a lot of drone inside the cabin. At highway speeds, you may hear a little bit, but it's really not gonna be something that's gonna give you a headache, it's not gonna prevent you from having a conversation with the wife or the kids in the back seat. They're not gonna be complaining.Now the entire system here is made from a mandrel-bent 409 stainless steel. It's also got the dual rear exit, that's gonna be the biggest change, of course, besides the sound. It's gonna go from the single-side exit dumping behind the rear passenger tire from the factory to a split-dual rear exit that goes straight back using dual 3.5-inch, 304 stainless steel tips that are polished with the Pypes name. Looks pretty good, in my opinion, it's one of my favorite exit styles.Now again, we'll break down the kit comparing it to the factory one in just a little bit. Note that the Pypes one here, the Violator system with the dual rear exit comes in just over the $500 mark, making it a nice budget-friendly cat-back. There's really nothing crazy about the cat-back, there's no bells and whistles. It's a pretty good budget-friendly, affordable system that changes the sound and the appearance at the same time, so it's a pretty good bang for your back kit.Now when you're installing this system, I'm gonna give it three out of three wrenches on our difficulty meter, not because it's impossible but it does, one, require you to cut your factory exhaust off right in front of that factory muffler. Two, it's also gonna require some patience in getting everything set up. At the end of the day, it'll take you about two hours from start to finish. Have a Sawzall on deck and some basic hand tools and you'll get the job done. I'm gonna take you through every single step of the process. Let's get to it.Tools used this install include an impact gun, extension, hanger removal tool, PB B'laster, 15 and 17-millimeter deep sockets, 14 and 17-millimeter wrenches, a Sawzall, some glasses for eye protection and a mallet. All right, guys, once you get your truck in the air, whether it be on a lift like we're using or on the ground using jack stands, just make sure it's properly supported regardless.What you want to do is break out a Sawzall or a cutting tool similar to this. Personal preference. I find a Sawzall to be a little bit easier using a thin curved metal blade. What we're gonna do is cut right in front of our factory muffler. This is the mid-pipe section, you want to leave the mid-pipe intact. Our new Pype system is gonna attach right about here and go straight back to the rear.So grabbing this tool, I'm gonna cut as close to the mid-pipe as I can here. We're gonna go right behind that weld, you just want to make sure you're not cutting on the weld itself. So cut straight through. I've got a pole jack here supporting the mufflers, so once we cut it off, it doesn't drop down too hard or too violently. We just want to support that weight which will make our life a little easier. Grab some glasses, of course, if you're using a cutting tool, you always want to be safe and just get to work.All right, the next step here, we're gonna pop our factory hangers off of the factory isolators located on the backside of the muffler. I'm gonna use a hanger removal tool. If you don't have one of these, guys, it's gonna be your best friend when doing the exhaust installs and uninstalls really. You can grab this at your local auto parts store or hardware store. Definitely, invest in this. If you're doing your exhaust here, it's gonna make your life a lot easier. So what I'm gonna do is just pinch this factory hanger right out of this exhaust isolator and do the same thing on the opposite side here.All right, guys, last step here, we're gonna grab our hanger tool and remove that last hanger from the isolator. I've got my buddy Joe helping me grab this all off in one piece because it's gonna dropdown. Have a helping hand on deck. If you're working on the ground it might be a little easier for you but grab your hanger tool and pop this guy out of the place.All right, guys, we've got our factory exhaust off of our Silverado here on the ground next to our dual rear exit Pypes Violator. I'm gonna take you through some of the similarities and differences between the kit starting toward the front end. Now, of course, we cut off that factory giant muffler and replacing it with the Pypes Violator. Pypes Violator muffler is exactly the cause of the sound that you're hearing from the Silverado.It is not too loud, not too obnoxious but it's also not super quiet, it's kind of that middle ground there. The Violator is known to be one of the middle grounds specifically from Pypes. The rest of the kit here is a 16-gauge mandrel bent, 409 stainless steel, 409 being more of that middle of the road. There's aluminized, 409 and then 304 as the top tier premium quality.This guy is right in the middle which gives you a stainless steel exhaust, so it's a little more rust and corrosion-resistant than its entry-level aluminized and it's also going to be something that's gonna hold up a little bit better in snow, salt, sleet, hail, all that good stuff. Specifically here in the east coast, we get a lot of that. We see a lot of road salt which can definitely take a toll on your exhaust as you can see from the factory system which has its points of pretty good rust, especially when it gets toward the heat source via the headers.Now moving on from there, the mandrel bends are gonna help with airflow, less kinks, less air restriction, and the dual exhaust leads right back to the rear end of your truck. Now as you can see, that's the biggest difference in the kit. Factory exhaust with a single pipe off-center from the muffler going out to the passenger side behind the rear tire. This is going to go instead of the passenger side behind the rear tire on the side exit, it's gonna go straight back here.As you can see when it wraps around the spare tire, it also has clearance, the pipe gets a little skinnier there to make sure it clears everything and it's not gonna cause any rubbing. So overall, well-built system. We're gonna install it on our Silverado starting right in front of the new Violator muffler with the extension pipe. So let's get to it.First up your guys, we're gonna grab this short extension pipe that's gonna go over the remaining factory exhaust before we throw on our muffler. Make sure you have one of the band clamps available. You're gonna put that over the inlet side and we're just gonna connect it. Now if it fights you getting on, you can, one, clean up the exhaust where you made the cut or two, grab a mallet and just try to start banging it on. Just want it to seat all the way through. Grab a 15-millimeter socket and tighten this down.Next up is gonna be the Violator muffler. What we're gonna do is take a U-clamp, we're gonna put it over the inlet side. And you want the inlet side on the driver's side of your vehicle. You don't want to flip it like this. Have it just like that and we're gonna set it over that extension pipe. Now just to support this, I'm gonna grab my pole jack and set it into place to hold up that muffler. Just to have a little bit of added support, set the muffler and have it horizontal. Grab a socket and tighten down this U-clamp. Starting on our driver's side for the outlet, we're gonna take another clamp and just set it on over the muffler.Now for this side, you're using the small over-axle pipe, you're gonna feed that over the axle and hook it into the hanger just like this. From there, you want to line up the muffler and this pipe here which may require some adjustment of the muffler. We're gonna jack this guy up, probably bring it forward a little bit to line everything up. I'm gonna loosen up the muffler back here and shuffle the muffler forward.From here what we can do is line up the muffler and this pipe and then tighten down that clamp. I like to get it nice and snug but still leave room for adjustment. Now before we continue this pipe around the spare tire, we're gonna do our passenger side here which is one straight pipe all the way back to the tip. So I'm gonna grab that, insert the clamp over the muffler just like we did before. Gonna loosen this guy up a little bit, slide that back. Feed this over the axle and attach it to the hangers.We have one hanger here and then one hanger directly over the muffler. Now we can head back to the muffler and hang it up there. From there, connect it right into the muffler. What we're gonna try to do is use a mallet to hit this hanger and seat it into the muffler. Now they're a little bit off angle but once it seats it should locate. If you have trouble with this, we might need to make adjustments to the position and the angle of the muffler itself.All right, guys. Now because our factory exhaust was a single side exit, there are no hangers set up on the driver's side to hold up your tailpipe. So Pypes includes this hanger. There is a hanger, a bracket, and an isolator. You want to slide the isolator over the end like I have it here. You also want to install it onto this large open hole in your frame right here. So if you follow your leaf spring all the way up right above that before the bracket. What we're gonna do is install this right in here like that. You want the hook end facing your driver's side.Now, guys, one thing I will note here is they do give you a bunch of washers. You want to make sure you're using a washer on the bolt head side and the lock nut side. But the lock nut side is gonna require a larger washer than what's included in the kit, so what I went out and did is I just went out and grabbed this giant washer.For comparison, here's the washer in the kit, here's the one I'm using. You can see this is just too small for this hole. What would happen is you'd go to put this on the inside, it's gonna fall right through. So I'm using a larger one, gonna sit just like that. All right, so you want to line that washer up with that pole, and now we can tighten it down. Now I'm gonna use a 14 socket and a 14 wrench to tighten this down.All right, guys, last tailpipe here on our driver's side. We're gonna hang the hanger here into that isolator that we just put up onto the frame. You wanna make sure you have the clamp here ready to go and you can tighten that down. All right, guys, at this point you can install your tips and then we can go back and make any adjustments we need to to line everything up. That's gonna wrap up my review and install as well as sound clip for the Pypes Dual Rear Exit Violator Exhaust System, available for the '07 to '17 5.3 Silverado 1500.
