    Hey, guys. Justin here. As you can see, actually working on my own car for once. It's a nice little change of pace. You guys always see me working on the project cars and the Bolt-on build-ups and all that stuff. Well, I wanted to let you in on what I'm working on with my own Mustang. I have mentioned my 1927 Ford a few times. I've been working on that at home of course, but I figured this was a great time to show you my main ride. Recently upgraded to the 2014 Mustang GT, track pack, some other little bells and whistles. Had to get the Recaro Seats, of course, which were a must. But anyway, we're doing some mods. Spring's just about here. So, it's finally time to start working on this thing. Concentrating on the suspension today, I'll show you guys a little bit more about that in a minute, but I had to get rid of that stock ride height. It was absolutely hideous. So, Ryan and I are working on that. But of course, I did take care of a few of the basic mods so far, so I got the C&L intake along with the Bama tune. C&L, just a great intake and if I can be a little cheesy here, the blue couplers do go nicely with those Boss coil covers if I may say. Also, I know it's a little silly, but had to get the hood struts in place. Just a nice mod to have especially when you're wrenching under the hood like Ryan's doing all the work right now. Just clears out a little extra space, so definitely a must have mod and then, of course, we did the exhaust. I actually am going with the quad-tip Magnaflow street series. They're already installed. I did the rear valance along with it which I had to cut the bumper up a little bit. You guys will see that of course, but I got a good game plan for this car. It's going to be a little aggressive, but I definitely want to go GT500 inspired, but I'm just going to have fun with it, see how it comes together. Now, we're actually going to concentrate again on suspension today and show you guys what we're working on. So, check it out. All right, guys. Definitely tackling some of the performance and suspension basics here today. For instance, we're installing the Koni STR.T shocks and struts along with the SR Performance lowering springs. Now, you guys hear me talk about those SR springs all the time. We use them on a lot of our project cars and I'm even trusting them on my own car because they're a great product. They give you one and a half inch drop on all four corners which I think is just right amount. It's not totally slammed, but again it takes care of some of that wheel gap and the STR.T's are great as well. The adjustables are nice, the Koni yellows, but for the basic use of just lowering the car, handling the lowering spring, giving you a little bit more of a sporty ride, the STR.T's are a way to go. The STR.T's are nice because you can use them with your factory top-hat or your strut mount and you don't have to use an 2005 to 2010 GT500 strut mount, but my case, I just really like to be able to dial in everything, so I'm going with the J&M caster camber plates up top here, which would really set off this package. All right, guys. Ryan and I just finished up the front. We've got the shocks in the rear, the springs in place. Now, we're moving onto the SR Performance Panhard Bar which we have installed already, but we're going to be making some adjustments and that's the important part with these adjustable panhard bars. SR does a great job, they offer double adjustability here because when you think about it, you lower the car with a standard length panhard bar and basically the rear axle wants to shift to the driver's side pushing the tire out further over there which is not a good thing. So, the adjustable bar gives you the ability to basically center the rear axle under the car which is huge in lowering of course, gives you the best performance and to do so you pretty much just got to rig up a crude little plumb-bob just to make your measurements. Load up the suspension. Make your measurements, make some small adjustments if you need to and then get this puppy centered underneath the car, so we're going to make our final adjustments and see how we look. All right, guys, so that's going to do it for today. Obviously we kept things pretty simple. Just took care of the caster/camber plates, spring, shocks, struts, and the panhard bar, but the car's finally looking good. Ride height wise, we got rid of that ugly factory wheel gap and I'm very happy with how the car's sitting now. I do have some wheels in mind for the car of course, but it is still a little nasty up here in the northeast. There's still a lot of salt on the road, so in the meantime I'm sticking with the Brembo wheels. Do have a little bit of appearance stuff coming up. You can kind of see where that GT500 theme's coming from and of course definitely going to dive into the engine bay and take care of some parts there. So, thanks for checking out my 2014 Mustang GT guys and stay tuned for more.

        will this exhaust fit a 2013 5.0?

        Will this be louder than the GT500 exhaust?

        Is this exhaust kit louder than the Corsa Sport? I'm trying to compare the two and decide which to buy.

        • The Cora Sports will be louder than the Magnaflow Street axle-back exhaust.

        Any way to make this fit 2010 GT (if I'm willing to cut the valance)?

        • This exhaust is designed to fit the 13-14 GT500 models. Unfortunately it will not fit a 2010 Mustang GT.

            Quad tips look great, fit could be slightly better

            I installed this axleback along with the GT500 rear valance and everything was very straight forward. I would have gone with the full catback but after all of the complaints about how the magnaflow over axle pipes don't work well with lowered mustangs, I decided to just get the axleback. I already have the LTH over axle pipes so it wasn't a big deal. These mufflers pretty much sound the same as the single tip magnaflow street mufflers that I replaced them with but they are slightly louder, and unfortunately drone a bit more. Its not that bad and I attribute this to having a full off-road exhaust, but at 2k rpm there is a lot more drone than with the single tip street mufflers. Just something to think about. The finish on these mufflers is great and the fit is pretty good although the passenger side hangs a bit lower than the driver side. Not a huge deal, but if you want a perfect fit you may want to stick with the OEM GT500 mufflers. I may visit an exhaust shop to see if they can bend the hangers to make it perfect but I am nitpicking as you can barely tell a difference. The exhaust note is nice especially in conjunction with long tubes and the quad tips just look awesome.

            Magnaflow Quad Streets

            These mufflers are awesome in my opinion. I went with the gt500 valance and these tips on my '14 gt and I love the look. The only problem I have with them is that they aren't perfectly symmetrical on the rear, the left tips do not reach as far out as the right ones do and the right ones are a little rotated. This is a MINOR problem and probably be fixed by tampering with the placement and hangers but it's not a big deal in my opinion. I was going to go with a pypes off-road x pipe as well because I feel like the mufflers alone are not enough if you want to be seen. Another problem was pricing but these were the only quad tips that I liked that were also chrome and not black or the gt500 ones. Besides this they have a great exhaust note and WILL be beasts with any off-road x pipe.

            Magnaflow axle back quad tip street. (2013-14 GT500)

            Easy to install, even with car just on jack stands. Not much louder than stock mufflers. These mufflers look fantastic.

            Very satisfied with the product

            Great sound, loud when you want it to be, installation was easy, very happy with the overall performance of the exhaust. Driver's side fit like a glove, alignment with the factory opening was spot on. Passenger's side installed just as easy, however, the alignment of the exhaust tips with the factory opening was off. Have not had any luck getting it where it should be.

            Deep exhaust note

            No problem with fitment on my 2014 GT. I combined with the Shelby GT500 rear valance that is required for the quad exhaust tips. This really added an aggressive look to the car. I couldn't be happier with the sound. A low growl that really kicks in at around 3000 rpm.
