      Video Review & Installation

      Hey guys, Adam here with and today we're taking a closer look at, listening to and installing the Magnaflow Competition Cat-Back Exhaust with Quad Round Tips in the polished finish. This will fit all 2015 and newer 3.6 Challengers. Now, if you're the owner of a V6 Challenger you might be looking to beef up that sound and as you just heard from our sound clips, this Magnaflow Competition is gonna do the trick. I'm gonna give this one right about a three out of five on our loudness meter. When you wide open throttle this thing it absolutely does bark but at idle and low RPM, it's really not overwhelming. I will say because this is, for the most part, a straight pipe, it's deleting the mufflers and really just has two high flow resonators, it does have some interior drone. Now listen, I've heard a lot of exhaust with a ton of interior drone that really gives you a headache. I don't think this is gonna be the case, especially at highway speeds, I don't think it's gonna be terrible, but I will say low to mid-range RPMs while cruising down the streets on your daily driver, this thing does have some humming on the inside. So, just keep that in mind moving forward. Other than that, we know the V6 is super quiet. This is definitely gonna give it a more aggressive tone and the Competition option from Magnaflow is gonna be there more high flow option meant to give you that increased airflow over their alternative which is more of a street-friendly that does include mufflers. So, there's really a couple of different preferences out there to fit whatever you'd like. But if you're looking for a more wide-open exhaust, Competition is the way to go. The whole kit's got a two and a half-inch 409 stainless steel material with mandrel bends. Mandrel bends basically meaning it's got a cleaner band that doesn't have as many kinks and airflow restrictions. 409 stainless steel is more of that middle of the road option. There's aluminized, 409 and then 304 stainless, 409 being that middle of the road option. It's definitely gonna be more durable than your factory exhaust. So, if you're located in wintry weather areas that see a lot of road salt, 409 or 304 is definitely gonna be the way to go. Now, this particular kit does change up the rear end look with your exhaust as well. The factory option has a rectangular tip as do most aftermarkets in the category. This one removes that quad tip to give you a dual round three and a half-inch polished stainless steel tip. It's really got a bright mirror-like shine to it at the rear, which I think looks amazing. I also think that quad round tip looks a lot better than the rectangular option, definitely strays away from the traditional Challenger look, but in my opinion looks pretty good. This one comes in right around the $1,600 mark which is expected with some of the higher quality materials. And the kit itself has pretty good welds, it does look like a really good quality system and it sounds pretty good as well. So, if you're looking for that change, 1600 bucks or just under that is going to be the way to go for this Magnaflow. There's a wide spectrum of price points in the category so it depends on what you wanna spend. Now, the install I'm gonna give two out of three wrenches on our difficulty meter. The factory cat-back comes off all in one piece from the cats all the way back to your tips. So, it can be a little bit difficult to do on the ground by yourself. I'd recommend having a helping hand on deck if you can, but you can absolutely do it yourself with the right hand tools. I'll recommend having a hanger removal tool on deck as well as PB B'laster to make life a little easier. Keep in mind guys this kit does give you the option to retain those factory rectangular tips which are separate from the exhaust itself. It's more of a trim piece that goes on the outside. It does include separate pipes to use if you wanna keep those factory tips but as you see we're going with the quad. Now, I'm gonna show you guys every step of the process for the install, it took me about two hours from start to finish. What do you say we get started? Tools used in this install include an impact gun, a ratchet, extension, 10 and 15-millimeter deep sockets, 10 and 13-millimeter swivel sockets are definitely recommended. 15-millimeter ratcheting wrench is recommended, hanger removal tool, PB B'laster, a mallet, and a pry bar. Guys first up here to get your factory cat-back out of the way is go up to your downpipes right after your cats were your X-pipe, your factory X-pipe connects. What we're gonna do is loosen up these two clamps right here with a 15-millimeter deep socket and an impact gun. It's at a little bit of a hard angle so if you need to you can use a ratchet. It looks like we're gonna need a little more torque, let's try that other one. Oh yeah, those guys are tightening rusty. We're gonna use a little bit of PB B'laster to loosen up this rust a little bit. All right. So, we got it broken loose with this ratchet here, we're just gonna loosen up these clamps. All right. So, now we're gonna tackle these hangers right under our rear suspension. Now, for these, I'm gonna use a hanger removal tool and if you don't have one of these, I recommend picking it up from your local auto parts store. You can rent one, you can buy one, super useful to have to because it's gonna make this a lot easier to pop out. I'm also gonna use PB B'laster again just to get that lubricated, that's also gonna make life a little easier, just hit both sides, the same thing over here. Now, I'm gonna take my hanger removal tool, and we're just gonna use this to pop the hanger out, just like that. Same thing on the other side. All right. So, the next two steps are pretty much the same. Now, we're gonna tackle more hangers, there's one on the front side and the backside of our muffler by our tailpipe tips. But instead of popping the hanger out of the isolator, I'm actually gonna remove the bolt holding that whole assembly to the frame and this is just a 13-millimeter bolt. I'm gonna use an extension and a 13 swivel socket, I find the swivel socket to make life a little easier. We're just gonna get this guy out. Keep in mind as you remove these two final bolts, the system's gonna start dropping down. So, make sure you have a hand there to support it. All right, now right above that exhaust tip there's another one and again, have your hand on the muffler ready to get it back down. All right, now same thing on the other side. All right, once you have this bolt off, the exhaust is gonna come down, we can take it off at one piece. All right. so, next up we got to get these tips out of the way. Now, there's four 10-millimeter bolts holding this on, I'm gonna use a swivel on an impact gun for the first three and then we'll grab a wrench or a ratchet to get that last one off. Let's make life a little easier here, if we take this bolt off, we can pull down that valance a little bit more and gain some more room. That's what we're gonna do here. With those tips out of the way, what we wanna do is disconnect this trim panel, and we're gonna re-insert that because it really rounds out this exhaust tip exit. And you wanna make that a clean look, so we wanna put that plastic trim back in place. So, grab those bolts you just removed and reuse them to get that back in. All right. Now, grab your 10-millimeter socket and tighten those back down. Perfect, repeat that for the other side.All right. So, we got our V6 Challenger's exhaust off the car and it's on the ground next to our Magnaflow Competition. Wanna take you through some of the similarities but mainly the big differences between the two kits starting at the front of the vehicle. Now, as you see behind me we are using an X-pipe in our Magnaflow kit, very similar to the factory exhaust, except this one's got mandrel bends, it's gonna be a little bit more free-flowing. The two and a quarter inch exhaust is made from a 409 stainless steel. So, the X-pipe and really the rest of the system is gonna last a little bit longer than that factory one. Aside from the X-pipe itself moving forward, you'll see we're putting in resonators right about the same location as your factory ones but that's about as far as it goes for the system with resonators and mufflers. It's a muffler delete at the tailpipe section as you can see, and the mid-pipe's just got a little bit more of a free-flowing resonator which is gonna help minimize some drone but it's also really just gonna open up that exhaust and let it flow freely. Otherwise, from there on, you're looking at about the same, again muffler delete, so that's not gonna be something that you're worrying about here. There's no restrictions going out the back end. Biggest change that you're going to see especially visually is the exhaust tips. Now, there's a couple of options when it comes to the exhaust tips. As you can see, we're now working with that dual two and a half-inch polished stainless quad tip. Now, the quad tip is gonna be a big upgrade or a big change from the factory using a single rectangular tip on each end, but it's really not much of an exhaust tip as much as it is just a trim piece. It's not actually attached to the exhaust. As you can see it's removable. So, it's a separate component, which I'm not really a fan of personally, I'm a huge fan of this upgrade here from Magnaflow. A lot of aftermarket Challenger exhausts are either gonna reuse the factory rectangular tip or give you an aftermarket one that pretty much looks the same. This I think is one of the biggest changes in the category. Again, two and a half-inch quad tips with that polished or mirror-like shine at the end and it's got the Magnaflow name laser-etched right on top, which I think looks very good. So, again, my opinion I think these are some of the best looking tips in the category, especially when it comes to completely changing that rear end look. However, if you like the factory rectangular tips more you have included pipes to use instead of these tips. So, those tips are welded onto this pipe here but if you want to retain them, use this pipe instead, you can keep that factory trim in place. So, the entire kit, start to finish, pretty much the same size diameter. As far as the materials go, you get an upgrade to 409 stainless steel, muffler delete, more free-flowing resonator, retaining an X-pipe. So, similarities, differences, but really the sound is gonna be the biggest change aside from the tips which you've heard in our sound clips earlier on. Now, when it gets to the install, we're gonna have to transfer over our factory hanger isolated from the mufflers that we've removed from the frame. We're gonna pop those off with a hanger removal tool and swap them over. And hit this with a little PB B'laster as well just to lube it up, same thing on the backside. All right, now repeat for the other side. Now, we could transfer them over. Now, if you're reusing your factory tips, can use this pipe here and put this on that. If you're using your new Magnaflow tips, you're gonna insert it over this hanger. What you wanna do is make sure this little tab here is facing the front of the vehicle, so away from the exhaust tips. All right. Same thing on the other side. All right. Now, this guy is just the ground strap, you can just hook this on to the hanger itself, just like that. All right. Starting at your headers here and your downpipes, we're gonna use these two extension pipes to attach them to the outlet there. Take note that one is longer than the other, the longer pipe is gonna go on your passenger side. Make sure you're grabbing the two smallest clamps included in the kit and putting them over the inlet here and then inserting them on to the factory exhaust. Again, smaller one goes on the driver side. You can use a mallet to tap that all the way back. All right. Grab your 15 socket and tighten down these clamps. All right. Next up we're gonna do our muffler system which is the X-pipe all the way back to these hangers. Now, before we get to that, I'm actually gonna take PB B'laster and just lube up the inside of the hanger on both sides. Now, for the X-pipe make sure you have two clamps over top of that inlet that's gonna connect those two pipes who just installed. The other end you'll attach the hangers. So, slide the pipes in first and then hook the hangers. All right. Now, you can slide the hangers into the isolators. At this point, we're gonna move our clamps back into position here where the pipes connect and get them nice and snug but not all the way tight, just leave a little room for adjustment. All right. Now we could take the S-shaped pipe for our passenger side and set it into place with another clamp on the inlet. All right. Once you have that slid into place, we're not gonna tighten this down, what we're gonna do is grab our 13 bolt and reconnect this to the frame up there. Slide the pipe in so that it reconnects to its position. Let's try to get this guy in at least a couple of threads, grab our 13 socket and extension and tighten that down. Same thing on the other side. All right. So, finally, we're just gonna do our Magnaflow tips. Again, if you wanna reuse your factory exhaust, just use that bear [SP] extension pipe with no tips on it, and then re-insert that trim piece we took off. We're gonna do this, so we're inserting our tip on far back as you can, center it in that slot, grab your factory 13 and you're gonna reconnect that hanger. Last step, do the same thing on the other exhaust tip. All right. Once you have your tips in place, go back, make sure everything is aligned properly. Make sure your tips are straight, tighten down all your clamps and you're good to go. That's gonna wrap up my review and install for the Magnaflow Competition Cat-Back Exhaust with Quad Round Tips in the polished finish available for all 2015 and newer 3.6 Challengers.
