      Video Review & Installation

      Hey, guys. Adam here with And today we're taking a closer look at, listening to, and installing the 2.5-Inch Cat-Back Exhaust, available for the '09 to '14 5.7 Hemi Equipped Challenger. As you just heard from our sound clips, I'm gonna give this guy a healthy four out of five on our loudness meter.Now wide open throttle, this is something that makes a ton of noise but it's still not as loud as the loudest possible option in a category, like say a Corsa Extreme, for example. This particular exhaust gives you a nice, really sturdy, crisp rumble at idle, definitely a loud bark at cold start and then once it warms up from red light to red light, you get a really nice mix of a good daily driver, something that gives you a more deep aggressive sound and a mix of some of the louder options once you start hitting the throttle up a little bit.Now this entire kit is made from a 409 stainless steel with mandrel-bent tubing which basically means it's great for corrosion and rust resistance for the guys especially located in wintery weather areas, seeing a lot of road salt, they can take its toll on your underbody, specifically the exhaust. It's also gonna keep the overall cost down because it's not as premium as 304 stainless, so it's great for the guys looking for volume, doesn't need the brand name and wants some good quality materials.Now this is gonna use a 2.5-inch mandrel bent diameter tubing, it's also gonna delete your factory resonator and relocate the mufflers to where the resonators used to be in the middle of the exhaust so now your tailpipe by the tip no longer has the muffler, it's more of a straight pipe section here. One thing that I'm not personally a big fan of with this particular kit is it doesn't include tips. You're gonna reuse your factory tips, or you can pick up tips from the aftermarket as long as it attaches the same way as your factory ones did. Now, we're gonna reuse our factory tips as you can see here but if you're looking to pick one up, you can definitely do so separately in the category just to upgrade your tips selection.This entire kit is gonna use U-clamps which do cross the pipes together so you want to make sure you're liking the way that this position before you tighten everything down because it can be a little bit difficult to make adjustments after the fact. Line everything up, tighten them down, and you'll be good. Now the price for this entire kit, like I said, a little bit more on the entry-level side of things, it's for guys who don't need the brand name, you're gonna be paying right around 650 to 700 bucks for this exhaust, making it one of the more affordable options in the full cat-back category for your Challenger.Now the install, I'm gonna give two out of three wrenches on our difficulty meter, there's no cutting or drilling or welding or anything like that, it is a direct bolt-on, just a little bit more involved in than say a cold air intake. I'm gonna show you every step of that process. It'll take you about two hours from start to finish. What do you say we get started?Tools used in this install include an impact gun, extension, 13-millimeter swivel socket is recommended, 13 and 15-millimeter deep sockets, hanger removal tool is recommended and PB B'laster or WD-40 or something similar. First up here, I'm gonna grab my impact gun, an extension and a 13-millimeter socket. And I'm actually gonna remove the hanger isolators directly from the frame unbolting them from the vehicle rather than using a removal pool and popping the isolators out. So we're gonna keep them all on one piece attached to the exhaust and just remove them from the frame. So go straight above the muffler, there's one behind it and one in front of it by the tips.Now, when you do the second one, you want to make sure you have a handle on the muffler because it's gonna want to drop down a little. All right. Now we can do the same thing on the other side. So now you can grab a hanger removal tool and head back toward the middle section of your exhaust here. Now on the driver's side, you have this flex tube, directly above that, there's a hanger in the isolator, I'm actually gonna pop this guy out.Now as you're doing this before you finish up removing the exhaust, it's a good idea to have a pole jack in place or a jack stand or something similar, maybe even a hydraulic jack, just to support the middleweight of the exhaust as you remove it. Now, if you have a helping hand during these final stages of unclamping it from the front of the vehicle that goes a long way. So I'm gonna grab a buddy to hold the tips while I remove the front then we can drop it all in one piece. Now you can grab your 15-millimeter deep socket and loosen up the 2 clamps holding them to your cat pipes.So we got our factory off of our 13 RT and it's on the ground next door 2.5-inch cat-back. And I wanna gonna go through some similarities and differences between the two kits and I want to start at the front of the vehicle. Now your factory mid-pipe here on your factory cap back is an H-pipe. Now the H-pipe has that crossover tube right in the middle welded between the two pipes which does restrict some of that airflow. Now you want to open up that free-flowing airflow so that you can get a little bit more horsepower and torque and overall just some more better breathing engine.Now when it comes to swapping over to your new system here, you're getting an X-pipe. Now the X-pipe has a smooth crossover instead of a hard stop right in the middle. That smooth crossover is gonna reduce the airflow restriction that's gonna give you a louder, raspier tone that you'll get from your new X-pipe as opposed to the deeper tone you would get from an H-pipe. It's overall gonna give you a small bump in horsepower and torque as well over the alternative.Moving on, you'll notice that your factory cat-back has resonators in the middle and mufflers by the tips. Now for your new system, you're relocating the mufflers to the middle where the resonators used to be and deleting the resonators. So by your tips as more of a straight pipe and the mufflers will be right in the center of the section there. Now those mufflers have just a little bit of baffling on the inside to keep down some of the higher-pitched drone sounds but it's also gonna give you that deep throaty aggressive tone that you heard from our sound clips earlier on.Moving on from that the entire system here head to toe is a 2.5-inch mandrel-bent, 409 stainless steel tubing, 409 being that middle-of-the-road material giving you better corrosion and rust resistance than say an aluminized tubing but not as expensive as the top tier 3 or 4 in the category. Now those manual bends are gonna help reduce all the kinks and the exhaust which you'll see a ton of in the factory cat-back. It's not mandrel-bent, it's got a lot of those kinks and airflow restriction, so you just have smoother bends with your new cat-back.Moving on again, again straight pipe, no modelers at the end, we relocated that back here. And finally, you have adapter pipes that'll go into the tubing for your factory tips. Tips are not included in this cat-back, I would've definitely liked to see some new tips in the cat-back but you can always pick them up separately if you want to get an upgrade. So with our factory system, I already snapped off the factory tips, that's just a 13-millimeter socket and they are slightly tack welded on which you can just bend off and they'll break right off so you can reuse them in the new system and then you just want to pop off your hangers which just slide straight off of the factory hangers so you can reuse those brackets toward the tips.So pop those guys off of your factory one, we already took care of that they're on our system. So what we're gonna do now is start with the install with our X-pipe. All right. Starting on your X-pipe here, you'll notice that one end the outlet end going toward the rear has two different style exits, one has a little bit of a curve and one is straight. The curve is gonna be on your passenger side. Make sure you have clamps over the inlet going into your factory cat pipes and slide that guy into place. All right. Once you have that on, bring your clamps back and tighten them down with a 15 socket.All right. So next up you wanna install your muffler. Now the muffler has an offset inlet and an offset outlet, the inlet going into your X-pipe is gonna be on the inside. Your outlet is gonna be facing the outside of the vehicle. You want to have one of those clamps over top and slide this guy into place. Once you have that slid in there, you want to make sure it's appropriately aligned. Now for this clamp, this style clamp basically crushes the pipes together, so you don't want to over-tighten them just yet, you want to leave room for adjustment so you know that everything is aligned properly because once you crush those pipes together, it gets pretty difficult to make adjustments.So if you are gonna tighten this down at this point, just get it a little snug and then we'll go back at the very end and tighten them down. All right. So you want to make sure this is just a little bit in from the edge and I'm gonna get it nice and snug. Like that. Do the same thing for the other muffler. All right. So next up, we're gonna do our tailpipe. I'm gonna start on our driver's side and I'm first gonna put a clamp over the muffler outlet.All right. So now we can take our exhaust pipe, slide it on, and we're basically gonna lift this up so it lines up and hangs up into the hanger above that muffler. All right. At that point, we can get this rotated up correctly and tighten down that clamp. All right. So next up we can take one of those factory hanger isolator brackets and slide it onto the new hanger on our pipe. Now it's definitely easier if you've lubricated with WD-40 or PD B'laster something like that. Once you have that on, lift it up and connect it to the frame using the 13-millimeter factory bolt.I'm just gonna thread this on by hand for now. We're gonna tackle the other one right in front of it by the tip and then we'll tighten them down. All right. So next up you want to make sure you're putting a clamp over this end. Grab the isolator facing the inside with the tab facing the front of the vehicle. We're gonna slide this on to that hanger on your adaptor pipe. Slide that guy into position and then hang this up onto the frame. From there you can tighten this down with that clamp.All right. Now to tighten up the bolt on the frame, I'm using an extension and a 13 swivel socket to make life easier, just tighten these guys down. All right. Now we can do the same process for the other tailpipe. All right. So now we're doing the exact same thing starting at our muffler, working our way back. All right. So now we can finish up with our exhaust tip, I'm gonna start on our passenger side. I'm gonna pop that guy on, make sure it lines up properly, then you're gonna tighten it down. All right. Once you have that tighten down, go back and tighten down all your clamps once you like the alignment of the tips. That's gonna wrap up my review and install for the 2.5-Inch Cat-Back Exhaust, available for the '09 to '14 5.7 Hemi Equipped Challenger. Get yours right here at
