So, MBRP's two and a half inch Installer Series Dual Exhaust system is hands down gonna be one of the most affordable and one of the loudest catbacks currently available if you own an '03 to '08 hemi-powered RAM 1,500. Now, as you just heard from our sound clips, this thing easily pegs my loudness meter. I'm gonna go ahead and give it a strong five out of five right out of the gate. If you guys live in the suburbs, you'll definitely be waking your neighbors in the morning with this system.Now, I'm happy to say, at this volume level, the Installer Series muffler still does a pretty good job of cleaning up the exhaust tone itself. You're not gonna hear a lot of gurgly or sloppy notes at idle, and it still sounds really throaty at redline, so you're not gonna get any raspy notes or crazy amounts of backfire like you might with a straight pipe setup. Now, even at this volume level, I'm also happy to say that the drone inside the cab isn't crazy. Yes, there is definitely volume present, but it's not gonna be anything that's gonna prevent you from having a conversation with your passengers, and it's not gonna be something that's gonna drive you crazy on the morning commute. Now, this is one of the most affordable systems, and that's for a pretty simple reason, it's made out of an entry-level aluminized steel. It's not a stainless steel setup, that's where some of those more expensive systems get their price from.Now, even though aluminized steel might develop signs of rust and corrosion a little bit quicker, it'll definitely still stand up to daily driving, and even if you live on the east coast or west coast, you see a lot of snow or rain, as long as you do a decent job of keeping the undercarriage clean, you shouldn't have to worry about developing anything like pinhole leaks or some crazy rust any time soon.Lastly, the MBRP system installs very easily. The new mid pipe on this kit is pre-measured for your cab and bed length, so there is no cutting required. You can get this installed with some pretty basic tools including some sockets, and a hand ratchet, and maybe a little bit of elbow grease. You can definitely get this done in the driveway. I'm gonna say you could probably get this system installed in about two to three hours perhaps. I'm gonna give the install a simple two out of three on my difficulty meter. It's definitely a big, heavy system, but it's not anything that you can't tackle at home like I just mentioned. So, again, if you want one of the most affordable and one of the loudest catbacks currently available for the hemi-powered RAM, go ahead and stick around. I'll show you guys exactly what tools you need in just a second and I'll walk you through every install step.To install your new catback, you will need a standard drive ratchet, a 14-millimeter deep socket, a 9/16ths deep socket, a 9/16ths wrench and a 5/16ths Allen key. Optional but helpful tools include a 14-millimeter intermediate socket, an impact swivel, an air ratchet, an impact gun, a pry bar, an exhaust hanger puller tool, and some spray lubricant.Now, obviously, before we install our new exhaust system, we have to remove our factory exhaust, right? That can be done in two primary steps. The first step is loosening a clamp here on the midpipe just above this crossmember, securing the midpipe to the Y pipe. In the case of our truck, it was a little bit too rusty, so we actually had to pull ours off with some channel logs. Now, obviously, if your clamp is in decent shape you can loosen it. Judging by the size of this rusty little bolt here, it's probably a 13 to a 16-millimeter deep socket that you'll need. At any rate, once you get this clamp free and the midpipe is free from the Y pipe, you can go ahead and pull all those factory rubber isolators and exhaust hangers. There are five in total to be exact. Two in front of the muffler, two directly behind the muffler, and one over the tail pipe itself. It's also very helpful to have some spray lubricant with you when you pull those. Once you got all five of those free, the entire exhaust will drop down. Go ahead and let the over-axle pipe rest on the axle, and you can actually pull the entire exhaust system out from underneath the truck.All right. So we have our factory catback removed. We went ahead and we put them up next to each other here, that way you guys can see some of the cool similarities and the differences to the Installer Series and our old busted factory catback, right? Couple of cool similarities to point out is the fact that you do not have to cut this thing. I mentioned it's a bolt on job earlier, and we're sticking true to that, that's all thanks to the pre-measured midpipe here specifically made for your cab and bed length, so that's really nice. You're also getting away with factory hanger locations, and small little thing to point out that I actually really like here. I don't like the way the factory hangers are on the original muffler. It's kinda tilted weird and it's kind of a pain in the ass when you're taking this thing on and off. That's not the case with the new install here. These are actually leveled out here so it makes the install a lot easier when you're hanging up the tail pipes. It's a crammed space, you want everything to play nicely, so I like that little design feature there.Now, other thing to point out here, we are going with a split rear exit instead of our single exit, but, installing the new hangers for the split exit is very straight forward. They provide all the hardware in the kit, you don't have to drill into the frame or anything like that, so that's really nice. That's where the similarities end. Cool differences to point out. Obviously you got this shotgun style muffler here. Pretty much a straight through design. It's got some baffling in there to kinda clean up the volume and the tone here, but overall, not restrictive whatsoever. That's a pretty big difference compared to our factory setup. You got this big ugly muffler here, and you got this resonator that pretty much kills any sound that might come out of that hemi motor. I also like the fact that MBRP addressed the tail pipes here. Obviously the factory system leaves something to be desired, that's not the case with the Installer Series, even though this is a very affordable system, they don't skimp out on quality where it matters in terms of aesthetics. I really love the tips on these guys. They're three and a half inches in diameter. They got nice rolled edges on the inside. Overall, they just look very well executed. I also really like the way they did the fasteners on the hangers, all you need is an Allen key to get those guys tightened down. So, again, pretty straightforward install. Without further ado, let me show you guys how to get the new system on piece by piece.All right. So the first step of our install is throwing on our new mid pipe. Before you do that, you wanna make sure you grab that largest D clamp in the kit and throw it on the end of the Y pipe there, that's gonna secure the mid pipe to the vehicle. Once you throw this thing up there, also make sure you have one of the clamps included with one of the hangers on there. You're gonna throw this guy into that first factory rubber isolator.All right. Next, you can throw your muffler in place. Now, it's helpful to have either a friend hold it up while you throw the tail pipes on, or if you're working by yourself, you can use a pole jack like I've got here. To secure the muffler to the mid pipe, you're gonna need to grab that other clamp with the provided hanger and to make sure that the hanger sits in the right location to tighten down later. You want the hanger facing towards the front of the vehicle. You also wanna hand tighten it, that way the muffler kinda stays in place while you throw everything else on after it.All right. Now that our muffler is in place and supported, we can prep for our tail pipes. We're gonna install the new hangers and rubber isolators provided in the kit, and like I mentioned earlier, you don't have to drill any holes into your frame, don't worry about that. There's actually two oblong holes on either side, I'll show you guys where those go. But, in order to tighten down the hardware for this hanger, you're gonna need a 9/16ths socket and a 9/16ths wrench.All right. Now that we have both hangers in place, we can install our tail pipes. Our tail pipes do go together as two pieces, so make sure you throw clamps on either end, then we can fasten everything together. You also wanna make sure you have clamps on the outlets of the muffler itself.All right. Now we have both of our tail pipes in place, now is a good time to check the fitment of your exhaust tips. Go ahead and throw those tips on the tail pipes on either side and see where they fit in a general manner. Then you can start tightening front to back. You wanna tighten all the clamps starting at the midpipe, work your way back to the tail pipes, that way you can get everything seated permanently. Now, some of these clamps are in a tight space, so you might need an air ratchet if you're using power tools, and you might be able to get away with a shallow socket. But, at any rate, you're gonna need a 14-millimeter socket to tighten down all those clamps. Once you've worked your way all the way back to the tail pipes and the tips themselves, you can finally tighten down your exhaust tips, make sure they're squared up one final time. In order to tighten down the exhaust tips, you're gonna need a 5/16ths Allen key.All right. Now that we're back here tightening our tail pipes down finally, couple of things to point out here on the driver side in particular. You may notice behind me, our axle is not under load right now so one of our brake lines is getting pretty close to this pipe right here. Once the axle is back under load, you should not have issues with clearance over that line. If you're a little bit concerned about heat and things like that, you could heat wrap it. It shouldn't be a major concern though. Other thing to point out, if you do have issues with your tail pipes kind of going to the left or right, or wanting to go a certain direction, you can actually reverse the directions of the rubber isolators and the hangers themselves, that'll make sure you can get the tail pipes squared up where they wanna naturally rest.All right. So, once you got those tips tightened down and you're happy with where everything is sitting, that'll wrap up the install, and that also wraps up my review of MBRP's two and a half inch Installer Series Dual Exhaust System fitting your '03 to '08 hemi-powered RAM 1,500.

MBRP dual cat back won't purchase again
Shipped timely, but I took the kit and truck to a shop with a hoist for installation. Good thing I did because we ended up having to add an elbow and short length of pipe to make the tailpipes match side to side...... My next replacement will be a custom bend system directly from the shop, I was not impressed with the gauge pipes or the fact I had to modify for proper fit.Helpful (3)
