      Video Review & Installation

      Justin: If you're looking to add more power and more sound to your factory or aftermarket exhaust setup, then the Corsa Cut and Clamp Double Helixx X-pipe might just be the option for you. Now, the Corsa will feature the 3-inch mandrel bent tubing along with that premium 304 grade stainless steel for right around 500 bucks. Now the install, it's going to involve a small amount of cutting so, therefore, AM will knock this one up to a soft two out of three wrenches here on the old difficulty meter and we will have a little bit more detail to come on that later in the video.So in my opinion, ditching the factory suitcase style resonator in favor of an aftermarket mid-pipe is a great way to totally transform the sound of a factory exhaust system. It's going to give you a noticeable improvement in bark along with eliminating some of the restriction, but at the same time, you don't have to commit to a full-blown often expensive cat-back. Now, on the other hand, if you've already added an aftermarket axle-back and you're looking to just crank things up a little bit more, well then adding something like this would certainly be a great way to achieve that. But what do you say we do talk sound after all here, guys, and with this puppy installed, the Corsa Double Helixx X-pipe along with the factory 2018 mufflers, the car really did have a tough sound along with a bunch of volume, so much so that I'm willing to go very, very strong three out of five on my patented one to five or one to wake the neighbor scale.Now, ultimately guys, I did go back and forth between a strong three and a soft four but ended up landing on that three as adding a different, maybe more aggressive axle-back, will certainly give you some more room for volume at the end of the day. But I will say one nice thing about leaving those factory mufflers in place is that the in-car experience, while a bit louder sure, is still relatively pleasant overall. But moving to construction and materials and nothing but the best here from the Ohio-based exhaust company as we've come to expect over the years. This does, of course, include that 304 L-grade stainless steel, 3-inch mandrel bends throughout and, of course, the star of the product, the Double Helixx or double X-pipe design.Now, this construction or design will certainly lend itself to a little bit more top end power on top of that very raspy growl that typically comes along with an X-pipe, when compared to your factory resonator or even an H-pipe. Now let's be honest, the Corsa mid-pipe here is not cheap, as is the case with a lot of the Corsa stuff but you're certainly getting a unique piece along with that really nice build quality. On the other hand, if you're simply just after a budget-friendly mid-pipe to ditch the resonator all together, there will certainly be more affordable options on the site.Now I should point out that the Corsa option here does not affect the cats in any way so it is 100% smog legal. It does not require a tune and won't throw a check engine light. And finally, it is designed to work with both active and non-active exhaust cars, in addition to both fastbacks and convertibles. But now let's touch on the installation and yes, there is some cutting involved but really nothing to be scared of. However, with that said, we are going to knock it up to a soft two out of three wrenches here on the site and a few hours from start to finish. And to give you a better idea of what's involved, here is a detailed walkthrough along with a tool breakdown.Tony: Tools used for this installation are as follows: small impact gun or ratchet, some sort of cutting device, this one we used a cut off wheel, a 15-millimeter socket, and a Sharpie to mark off where we cut.Now to begin our installation of our Corsa Resonator Delete, what we're going to have to do is go ahead and cut our factory exhaust. Now to measure where it needs to go, the way I like to do it is I like to put all the connectors on to it, hold it up to the exhaust, and line it up right where it's going to need to be. So what I'm going to use is a pole jack. I'm going to hold it up in place, line it up exactly where it's going to need to be, and then just mark our exhaust with a Sharpie. And when we go to cut it, we're going to use a Sawzall or a cut off wheel. Now let's go ahead and get started. Now as you can see with our X-pipe, I have our end slipped on, on both ends. I don't have any clamps on yet. We don't need them just quite yet. But just for measurement's sake, I have the ends slipped into them. Gonna go ahead, set it up here on our pole jack. Now, when lining it up, I generally like to line it up right where the bends are. On this side, it's lining up. Over here, it's a little bit different but it's roughly right where it needs to be. Now, when marking off, you gotta remember that your stock exhaust is going to slide into your end cap here. If you line up your marks right with this weld, you should be good to go. That'll give you a little extra space just to slide it back and forth just to line it up perfectly.Now let's go get our Sharpie, we're going to mark those off, then we'll get our cut off wheel, and get that started. Right here along this weld should be plenty of room. Gonna go ahead and mark that right there. And do that on both sides. Now that we have our stock exhaust marked, we're gonna go ahead and get our new X-pipe out of the way and we'll get a cutter, and we'll cut the pipe, and we'll slide it all together. Now I'm going to begin my cut using my cut off wheel. Now, make sure when you're using anything that cuts metal or anything that cuts anything, you wear eye protection. I have prescription glasses on so these are gonna have to do for me for right now. I do not have the ones that fit over these, but make sure you at home wear eye protection.Next, we're gonna go ahead and loosen up our factory clamps here on our extension pipes that come off of our catalytic converters. Now we're going to do that with a 15-millimeter socket. Once they're loose, we can go ahead and just slide the whole mid-pipe out and go ahead and get started to add in our new one. All right, now that our factory mid-pipe is out of the way, we're going to take our new extensions that go on the back of our new one and we're just going to slide them over our tailpipes all the way on that our tailpipe sticks through the other side of it. This way, when we slide our new X-pipe up in place, we just slide them back over and we don't have to take our rear mufflers off.Make sure that you put your clamps in place now because later down the line, you might have to take it all back apart to get the clamps on. All right, go ahead and just slide your other clamps into the place. Now with your new X-pipe, go ahead and put in your front adapter pipes, and your clamps, get them in place. Now we're not going to tighten any of our clamps up just yet. We're going to wait until everything's in place so we can go ahead, align it up, and tighten it all down, and it will be good to go. Let's go ahead and slide your front pipes in. Now, once you get your X-pipe slid up into your front pipes, you can go ahead and slide your adapters from your muffler over your X-pipe and then have a friend help you align them. Have him maybe stand behind the car and adjust the tips and hold your muffler straight while you go ahead and start tightening up your clamps.Now when it comes to tightening up my clamps, I usually like to work my way from the back forwards. In this instance, I'm actually going to work my way from forwards backwards. Because we're only doing a mid-pipe, we can get the front of our mid-pipe locked down in place and have it nice and level then we can come back to our mufflers, straighten them up, have someone eyeing them up for us, and go ahead and lock them down. Now to lock them down, we're going to use the same 15-millimeter we used on our original clamps, and we're even going to use that on our new clamps that came with the kit. All right, now that ties up the installation of our Corsa resonator delete on our 2018 Mustang GT and I hope you enjoyed this video.
