So if you own an '04 to '08 4.6-liter-powered F-150, and you wanna upgrade to a dual exhaust system, but you wanna do it as cheap as possible, then you should be checking out MBRP's Installer Series Dual Exhaust System with the split side exit configuration. At around the $400 price point, this is currently the least expensive dual exhaust system available for this truck, and that's for a pretty simple reason, it's made out of aluminized steel instead of stainless steel. Now, that's not to worry. Even though it's not stainless, you don't gotta worry about this thing rusting out on you anytime soon, as long as you do some occasional maintenance and cleaning underneath the truck itself. And where it does matter most, the stainless steel tips there are made out of factory-grade 409 stainless. So it's safe to say those things will clean up just fine. They won't show signs of rust or corrosion anytime soon, and they'll look good where it counts for years to come. Now, as far as volume is concerned, this system does open up the sound of the motor, has a nice, deep, throaty idle, keeps things throaty through the RPM band all the way up to the red line. It's not overbearing, and I'm happy to say there's actually really no interior drone inside the cab whatsoever. You can hear the exhaust from out back, but it's not that kind of resonance that's gonna be buzzing in your ears all the time. Certainly, a big factor to think about if you have a daily commute, you got passengers, family and friends. You don't wanna interrupt a conversation, right? So as far as volume is concerned, I'm gonna give this a healthy three out of five on my loudness meter. It'd be perfect for a daily driver and, again, for something that you don't wanna hear inside the cab but you still wanna turn heads when you zip on the pedal a little bit. Now, as far as the install goes, pretty straightforward. Technically, a bolt-on job. You might have to make a simple cut to the provided mid-pipe just to size it up for your cab and bed length, but that's a cut that you can do at home with a Sawzall or a cut-off wheel. So for that reason, I'm still gonna give the install a pretty simple two out of three wrenches on my difficulty meter. I imagine it'll probably take you about two to three hours to get this system installed. Now, if you don't like the split side exit configuration and you wanted something a little bit more classic, you should know that MBRP makes the Installer Series with a dual rear exit configuration, gives it a little bit more of that classic street rod look. But, personally, this would be your favorite if you enjoy that factory side exit configuration and you want to replicate it on the other side. So again, if you want the most affordable dual exhaust upgrade for your 4.6-powered F-150, you want just the right amount of volume but nothing that's too overbearing, then the Installer Series should be at the top of your short list. And if you do decide to go for the Installer Series, you can actually come back to this video in just a little bit because I'm gonna show you guys exactly what tools you need to get the job done, just a couple of sockets. And I'm actually gonna show you how to get this installed step by step. All right, guys. Before we get started, you'll need a standard drive ratchet, a 5/16 Allen key or Allen-head socket, a 1/2-inch deep socket, a 9/16 deep socket, and a 15-millimeter deep socket. Now, optional but helpful tools include a mallet, an exhaust hanger puller tool, a hammer, an impact gun, spray lubricant, and a prybar. All right. So obviously, we have to remove our factory exhaust first. In order to do that, we have to separate our mid-pipe from our factory Y-pipe just behind this guard right here. It's secure with a barrel clamp, with two 15-millimeter nuts and two studs, so we need a 15-millimeter deep socket to loosen this. All right. So once you've separated that clamp and you separated the mid-pipe, the next step is spraying down the three rubber isolators that secure all of the exhaust hangers on the factory exhaust. Now, you'll need some spray lubricant, some PB B'laster or WD-40. Let those soak for a minute, let that oil get into that rubber, and that's gonna free things up. Then, what you're gonna do, you're gonna grab ahold of the cat-back, you're gonna push it towards the rear of the truck, and then you can actually pull all those exhaust hangers out of those rubber isolators. The exhaust will drop free. Make sure you don't have that thing come down crashing on you. Then, you can actually pull it out underneath the truck as one piece. Now, if your truck has some mileage on it, you might have some rust on those exhaust hangers. So it might be helpful to tap at them with a hammer or something, help break them free. All right. So we have all those rubber isolators sprayed down. They've been soaking for a minute. Again, you wanna have a friend with you, and you wanna take your time when you do this. You're gonna be pushing the entire system back towards the bumper until all of those exhaust hangers are freed out of those rubber isolators. Now, again, if there's rust and if there's resistance, very helpful to have a dead blow mallet, and even a big prybar. You can press that up against the muffler and get a little bit of leverage. But at any rate, just take your time with this because it is a little bit heavy. All right. So we have our factory exhaust removed. Quick comparison here. Couple things to point out here. We are going from a 2 1/2-inch mid-pipe to a 3-inch mid-pipe, and then you can see our new MBRP muffler is way smaller than our factory muffler. So that's where you're getting all that nice, deep volume and tone from. Now, exiting the muffler here, we step back down to 2 1/2-inch here for both of our tubes on either side, keeps things nice and throaty, keeps that exhaust at idle from sounding too gurgly. And then we have our really nice rolled, polished stainless steel tips. Those are made out of 409 stainless steel. You don't have to worry about those rust or corroding anytime soon. And then, even though we're going from a single exit to a dual exit, there is a hole that is actually predrilled in the frame rail, so don't gotta drill anything. And then, that's where we're gonna be using that speed clip in order to get that new rubber isolator and exhaust hanger in place. We're also retaining all the locations for our factory rubber isolators and exhaust hangers, so you don't gotta worry about modifying anything on the mid-pipe, the muffler, or on the passenger side. Now, depending on your cab and bed length, you might have to make one cut to that extension pipe, like I said earlier. And in the case of our truck, we're working with a SuperCab with a 6 1/2-foot bed, so we have to cut our pipe down from 44 inches to 37 inches. So we're gonna head over to our chop saw real quick, we'll cut that off to the correct length, and then I'll show you guys how to get the new system bolted up. All right. So we cut up our mid-pipe. We cleaned up the end there. Now, we can throw it onto our factory Y-pipe. In order to secure this to the factory Y-pipe, we'll need one of those saddle clamps in the kit, and you'll need a 9/16 deep socket to tighten it down. All right. Next, we can throw our muffler in place. But before you do that, make sure you grab that clamp and hanger combo, throw it on the end of the mid-pipe, and also thread that hanger into that first rubber isolator. That's actually gonna cinch the mid-pipe to the muffler. Now, you'll need that 9/16 deep socket once again. All right. Now that our muffler is in place, we got some clamps on our outlet tubes here. We're gonna throw on our over-axle pipe for our passenger side. And we're not gonna tighten this clamp down yet until we get the tailpipe in place. All right. With the over-axle pipe in place, we can install our passenger-side tailpipe and exhaust tip. Now, getting this guy in here can be a little bit of a pain because you gotta line up the pipes, and you also gotta line up that exhaust hanger and that rubber isolator and it's a bit of a squeeze, that's why we left the over-axle pipe loose. Now, once you get this in place, you can throw the exhaust tip on. And you're gonna need a 5/16 Allen key or 5/16 Allen-head socket in order to secure the exhaust tip to the tailpipe. All right. So our passenger side's all buttoned up. We can install the driver side. But before we do that, we're gonna install the hardware for our new exhaust hanger. So you're gonna take this speed clip and you're gonna thread it through the little square hole up here on the frame rail, just above the leaf pack, into a little round hole. I'll show you guys in just a second. Once you've done that, go ahead and grab that little bolt with the flat washer, crush washer, go ahead and grab that exhaust hanger, sandwich all that stuff together. Make sure it's nice and tight. Then, we can continue throwing on our over-axle pipes, tailpipe, and exhaust tip for our driver side. All right. So our exhaust hanger is in place. That was a 1/2-inch deep socket, by the way. Now, we can throw on our over-axle pipe, tailpipe, and exhaust tip for the driver side. Same process, make sure you got clamps on either side of these, so you can tighten them down with your 9/16 socket. And then, when you get to that exhaust tip, you'll need that 5/16 Allen key or Allen head socket to button this up. All right. Once you got that driver side exhaust tip installed, do yourself a favor, double-check all your clamps, make any final adjustments that you might need to square everything up, and that'll wrap up the install. And that also wraps up my review of the MBRP Installer Series Dual Exhaust System with the split side exit configuration fitting your '04 to '08 4.6-liter-powered F-150. I'm Travis.
