So if you own a '09 to '18 Ram equipped with the 5.7 Hemi and you are looking for arguably one of the deepest sounding exhausts currently available, you should be checking out the MF series dual exhaust system from Magnaflow. Like I said, this favors tone over volume. Actually gonna give this a strong two out of five on my loudness meter. It's gonna be on the quieter side of things, which is perfect if you daily your truck or you have family, you have a long commute, you take long trips, things of that nature. Now, besides the fact that the MF series does sound really good, I'm a fan of it for a few other reasons. At around the $800 price point, it's in the middle of the road, maybe a little bit more on the affordable side of things, but it's still really high-quality. It's actually made out of factory 409 stainless. So if you daily your truck, you live on the East Coast or West Coast or you see a lot of snow and rain, rust and corrosion will not be an issue. So that's really nice. They also improve on the factory exhaust tip look. These are actually an inch wider in diameter. They keep that nice polished finished with the rolled [SP] tips on them, but they're a little bit louder and prouder. So overall I think it's a nice improvement. Other reason I really like this system is you do not have to cut or add in a new mid-pipe. This reuses your factory mid-pipe. So all you're doing is pulling your tailpipes and your muffler. So the install is actually a lot easier than most other exhaust systems for the '09 to '18 Ram. So if you like the way the MF series sounds and you like the fact that it installs very easily, you should stick around. I'm gonna show you the install step-by-step. It's very easy, one out of three wrenches on my patented difficulty meter. You should actually be able to get this done in the driveway in about two hours. So without further ado, let's go ahead and get started. To install your new cat-back, you'll need the following tools: a drive ratchet and a 15 millimeter deep socket. Now, optional but helpful tools include a swivel socket, a dead blow mallet, a cordless impact, some spray lubricant, and a pry bar. So before we install our new cat-back, we obviously have to remove our original exhaust starting at the tailpipes. You're gonna remove two rubber isolators on the driver side, one rubber isolator on the passenger side. But before we do that, we wanna loosen the clamps holding the tailpipes to the muffler. To do that, you're gonna need a 15 millimeter deep socket. And if you're using a power tool like me, it's helpful to have a swivel on there because it is a tight fit. All right. So with our tailpipes removed, it's time for us to remove our factory muffler. Generally, the same steps, you're gonna loosen the clamp in front of the muffler. Again, you're gonna use that same 15 millimeter deep socket. And you have two rubber isolators holding the muffler to the truck. You wanna spray those down, make it easier to remove them. Now, if your truck has some miles on it, it might be a bit difficult pulling that muffler from that mid-pipe. So if that's the case, you're gonna grab my favorite tool, dead blow mallet. Tap on the front here, that should help break it loose. So now we have our factory cat-back removed from our truck. We did mock up our new system. That way it's easy to see where everything's supposed to go. A couple of cool differences and similarities I wanted to point out between your factory system and the MF series. The MF series is made out of factory grade 409 stainless. So if you daily your truck or you take it off-road or you see a lot of rain or snow, this thing will stand up to rust and corrosion. It's safe to say this thing will last for years to come. Really cool thing that I like about the muffler, Magnaflow says that this is actually technically a straight through muffler. So you can see it's smaller than the factory muffler, but it's still pretty damn big. What that results in basically is a large resonating chamber. That's where you get all that really deep sound that the MF series is known for. Moving down the line here, you can see that the flow tubes on your factory system are two and a quarter inches. These actually step up to two and a half inches and they delete those annoying little resonators that really kill the sound of the Hemi. So it's safe to say that this thing's gonna be really deep. It's gonna be louder. It's gonna be a lot more free-flowing. Then down to business and [SP] you can see we have some massively improved exhaust tips. Your factory tips are polished, but they're a little bit small in my personal opinion, they're four inches in diameter. These are actually five inches in diameter. You can see they're also way bigger overall. So overall, they're actually gonna look a lot nicer once installed. Other than that, these do reuse your factory hangar locations. So it makes for a really easy job in terms of the install. There's no custom modification needed. Don't gotta drill any holes into your body or frame for new hangers or anything like that. So without further ado, let's go ahead and get the new MF series installed, shall we? First thing's first, we're gonna install our new muffler. To do that, you're gonna grab the largest band clamp in the kit. It's a three inch band clamp. Throw it on the flared end of the muffler. And you're gonna throw the muffler up on your factory mid-pipe. Now, it's helpful to have a friend hold this in place while you get the rubber isolators on the hangers. I'm working by myself today. So I got my friend, my pole jack here. We're gonna keep that in place, level it out, then we can throw the rubber isolators in place. Now, you can see behind me, we threw two of the two and a half inch band clamps on the outlets of the muffler. You'll want those in place before you slide the flare end of your over axle tubes onto those outlets. All right. With that over axle tube in place, we're gonna install our tailpipe with our exhaust tip for the passenger side. Before you throw it up there, make sure you grab another two and a half inch band clamp. Throw it over the flared end of the pipe and then you're gonna secure it onto the rubber isolator before you slide it into the over axle. All right. Our passenger side is all set up. We're gonna do the same thing to our driver side. Again, it's the same process. Fit your over axle pipe into your muffler. Make sure there's a two and a half inch band clamp on the driver side outlet of the muffler. Also make sure you put your hanger up into that first rubber isolator. Once you're over axle tube is in place, go ahead and throw your tailpipe on, again, same deal, grab another two and a half inch band clamp, put it on the flared end of the tailpipe, make sure you hang the tailpipe in that final rubber isolator. All right. With both your tailpipes in place, the last step is tightening down all of our clamps. You wanna make sure that both your exhaust tips are lined up and squared off. Once you've done that, drive home all those clamps. You'll need a 15 millimeter deep socket to do so. So as you saw, the MF series does install quite easily. Again, we're just working with a muffler and tailpipe. So it's a pretty simple setup. Other than that, that also wraps up my review of the MF series dual exhaust system with the rear exit configuration from Magnaflow fitting your '09 to '18 Ram equipped 5.7 Hemi. I'm Travis.
