    Hey guys, Stephanie with, here with the DCI Underbody Heatshield for all 2015 and up S550 Mustangs. The DCI Underbody Heatshield kit is a good option for the owners out there that are concerned with cabin temps being affected by the exhaust or the underbody in general. This could apply to both stock and heavily modified cars. And either way, if you have high underbody temps, it could have an impact on the driving experience and I don't mean a positive one. Underbody temps may seem like a trivial topic, but I'm going to go ahead and disagree with that. I'm sure a lot of you guys have already heard by now, but if you haven't, there has been a safety recall in the EcoBoost due to elevated underbody temps. The temps that are being created by the EcoBoost exhaust are much higher than expected and it's actually creating a safety issue. Ford is fixing the safety issue, but this has nothing to do with the cabin, so the fixes from Ford could still leave the cabin hot. This kit is designed to block the underbody heat from entering the cabin, therefore reducing interior cabin temps and luckily, this kit from DCI is going to fit all 2015 and up Mustangs. This means the V6, EcoBoost, GT and, Shelby GT350 models. And this isn't just relevant for the EcoBoost either. It's ideal if you're running an aftermarket exhaust since they tend to create more heat and in the world of exhaust, more heat isn't necessarily a bad thing if you're thinking about performance. Keeping the exhaust temperatures high keeps the velocity high and you want a high velocity exhaust. It means improved exhaust scavenging and this is relevant for both NA and forced induction cars. So we want the heat, we just don't want it in the engine compartment or near us. This kit has a few different pieces to it. It's going to protect the floorboards and the center bearing from the heat and it's going to work alongside the factory shielding so you won't be removing anything, just adding on for some extra protection. The front floorboard and center bearing shields are rated at over 1000 degrees Fahrenheit and this kit also comes with exhaust pipe shields that are rated nearly the same. The high temp ratings make the kit usable in all applications: street, strip, and drag applications. So usually, one of the first concerns with a kit like this is weight. A lot of times, weight can be a downside, but that isn't an issue with the kit from DCI. It's very lightweight, which is good news. When it comes to price, this kit costs just over $350. It is a five piece kit that is pre-cut and will work on all S550s. It comes with the new hardware and another plus is the easy install. So, like I said, this will be an easy install and you don't need much mechanical experience. The kit installs with mechanical fasteners, so you won't have to make any permanent modifications. And like I mentioned earlier, this kit works in conjunction with the factory components that are already installed, so you won't have to uninstall anything either unless you're an EcoBoost and in that case, you will need to drop an exhaust tank. The kit can be installed in less than an hour and I'm going to call it a one out of three wrenches on the meter. You will need a few different sockets for the install and I'd also recommend some safety glasses and gloves and a long-sleeved shirt for the install if you have allergies that might be affected by the material. You're going to need to get under the car, so either a lift or jack and some jack stands will be needed and your best bet is to let the car cool before starting the install. DCI suggests installing the center shield first, then the front extension shield, which will fit behind the factory shield and share a fastening position with it. These pieces are just bent into place so they line up with the mounting locations and you just want to make sure that you're bending them so they line up and sit tight up against the car, up into the contours of the fore, and away from the exhaust. The kit comes with washers and nuts to attach the shields with and the clamps for the pipe shields, which just install between the exhaust and the fuel tank with the clamps. Wrapping things up here, the DCI Underbody Heatshield kit is an effective way to keep underbody heat from entering the interior in the cabin. The kit works with the factory shields to give some extra protection and all components are rated for extreme heat, which makes the kit suitable for all different kinds of applications.

    Stay Cool. When installing an aftermarket exhaust or modding for more power, exhaust temperatures can increase and soak into your Mustangs interior leaving you hot and bothered. However, DCI's Underbody HeatShield Kit was designed to add an extra level of heat protection, when compared to the factory shields, to keep you cool and comfortable.

    Handles Extreme Temperatures. DCI developed this HeatShield Kit using OEM technology and years of experience to identify the underbody areas that would become an issue once aftermarket exhaust modifications were introduced. The front floorboard and center bearing shields are rated to 600°C (1112°F), while the exhaust pipe shields near the gas tank are rated up to 1000°C (1832°F). Making DCI Underbody Heat Shielding ideal for street, strip and drag applications.

    Straight Forward Installation. The DCI Underbody HeatShield Kit installs easily with mechanically fasteners, there are no permanent modifications required. The kit can be installed in less than an hour.

    Application. This 5 Piece DCI Underbody HeatShield Kit fits all 2015-2019 Mustangs including the V6, EcoBoost, GT and Shelby GT350 models.

    Curious about the clamp on shields for near the fuel tank... Will the clamp on shields and supplied clamps fit 3" pipes correctly?

    • The DCI Underbody HeatShield can be used with 2.5" or 3" exhaust.

    I have a street cat-back exhaust installed. Will this kit make my quieter inside the cabin? And will the pipe shields make the cat-back quieter? I don't want either of those consequences.

    • The DCI Underbody HeatShield is designed to reduce temperature inside the cabin caused by aftermarket exhausts. While you might notice a slight change in interior noise, it will be minor. There will be no change in exterior exhaust volume.

      Pricey but better safe than sorry

      Planning to install catted long tube headers that relocate the cats further back where there is no shielding it seems wise to install these. Doing lots of highway DD duty I wanted to avoid the risk of potentially scorching the underside of the carpet which would cause a smell you could never get rid of. Note the clamp-on shields will fit 3" pipes but the supplied clamps just barely. (may want to replace the clamps)

      Nice idea

      It's a really good idea. You don't show off the bottom of your car, but I didn't notice my exhaust had a leak cause it was catching it so that was my only probably with it. Other then that good product
