    Review & Installation Video

    Review & Install Video

    Hey, guys, Stephanie with americanmuscle.com here with a review of these MBRP Long Tube Header and Mid Pipe Kit, available for 2015 and up S550-GT Mustangs. In this video, we're gonna be looking at a few different things in regards to this kit. We're gonna talk about the materials and construction of the headers and the mid pipes themselves and the install too. I'll talk more about this later, but I can tell you right now that long tube headers make for a difficult install, so I'm gonna call this one a three out of three wrenches in the difficulty meter. This kit from MBRP that includes long tube headers and matching mid pipe connecting pipes is gonna be a good option for someone looking for a natural finish, off-road long tube header for both performance and sound gains that comes with the matching mid pipe connecting pipes and makes way for a continuing three-inch cat-back. If we start with the heart of this kit, we'll be looking at the headers. Long tube headers are gonna offer both performance and sound gains, but the end result of your headers will depend on the rest of your setup. The runners on these particular headers are one and seven-eighths inch, which is slightly different than the one and three quarter-inch offering. Traditionally, you see forced induction cars running the larger runners, and NA cars running the one and three-fourths runners, but I wouldn't really say that's a hard and fast rule, especially with the new Coyotes. So you don't have to have a blower to run a one and seven-eighths diameter. You just need to keep in mind your current mods and the goals you have for your car when you're looking around, as well as what going with this size runner will do to your power band with the mods that you currently have. If you have some bolt-ons and you're still NA, you might see a hit on your low-end torque, but once you spend that Coyote motor up, the larger diameter's gonna help keep things moving, so that what you're going to see are top end gains. Getting into the specifics here, these are a 304 stainless steel header that have a natural or raw finish, which is gonna be different than a chrome or ceramic-coated header. It obviously doesn't have the polished appearance that a chrome header would have. And while these do not have the ceramic coating either, they are made from that 304 stainless steel tubing, so you won't have to worry about corrosion, and not to mention you get to see the beautiful welds since these do have that raw finish. And this is manual bent tubing, which is gonna help with smoother air delivery. The primary tubes then merge down to three-inch collectors, and MBRP has these header flanges here that are laser cut, and they do that to prevent leaks and create a good fit. Then you have your connection pipes here. These are three-inch pipes, and those are gonna connect down to your mid pipe. They're three-inch, like I just said, and they are all off-road pipes, so they're gonna require a three-inch cat back to be bolted up to them. And if you didn't know already, when you change your header setup to a long tube setup, you also need to change your mid pipe to a shorty mid pipe to work with the long tubes. So just keep the three-inch requirement in mind when you pick out your cat-back, or at least your mid pipe. If we move on to price, as we all pretty much know or you know if you've been shopping for long tubes, that they're pretty much gonna be a solid investment. They're pricey and they're difficult to install. The option from MBRP, since they are a higher quality item that's more at the top of the food chain, are gonna be on the more expensive side. The one and seven-eighths options that we have here are gonna be slightly more expensive, which isn't unusual to see. You do tend to see the larger runner costing more than the smaller runners, but not usually by very much at all. You're looking at spending between $1,100 and $1,200 for this kit, and that's why I call long tube headers an investment. You do have to keep in mind all of the benefits and power that you'll be getting from a setup like this one here, and, to put things in perspective, it's not just MBRP that's gonna be expensive. You're looking at headers costing over a grand anyways. As for the install on this one, long tubes are going to be a difficult install. I don't say this often, but if you don't have a helping hand or you don't have much experience, it might be better to just take the car to a shop for the install. If you do tackle this yourself, it's gonna be a full three out of three wrenches on the scale, and a day in the garage, especially considering that you'll be installing a cat-back or at least a mid pipe with these headers. You can do it on a jack and jack stands, but a lift would certainly make this easier, for sure. You're gonna need your tool box for this one, with an assortment of different sockets, wrenches, and extensions. You're looking at things like disconnecting the steering shaft, dropping the starter, and removing a motor mount. A lot of this install requires working in some pretty tight areas. So while everything is straightforward, getting access and maneuverability in these areas is actually tricky, which is why you need to pull the motor mount on one side, so you can raise the motor slightly with a jack to give you some more room. And having a helping hand in this case is really gonna benefit you, but a day of wrestling and some pretty pennies spent on these mods is totally worth, in my opinion. So wrapping things up with the MBRP long tube headers, these are 304 stainless steel headers. They come with off-road mid pipe connection pipes that are three-inch. The headers have one and seven-eighths inch runners, and you will need a three-inch cat-back to pair with these headers. As usual, you can check them out more online for yourself right here at americanmuscle.com.

    Power and Sound. Maximize both the performance and sound of your 2015-2019 GT exhaust system with MBRP's Long Tube Header Kit featuring a 3" Off-Road Mid-Pipe. These 1-7/8" Long Tubes by MBRP are crafted from superior T304 stainless steel and will deliver better exhaust flow and lower exhaust temperatures. Improve your Pony's horsepower and torque with upgraded 3" collectors and the use of a required MBRP 3" Cat-Back (sold separately).

    Efficiency and Quality. The 3" pipes of these MBRP Long Tubes are mandrel-bent for precision, leading to smooth exhaust flow. Designed to eliminate your Mustang's catalytic converters, the 1-7/8" primaries maximize power and the T304 stainless steel construction means they'll resist corrosion and discoloration. This Long Tube Header Kit with Off-Road Mid-Pipe is specifically designed to install along with an MBRP 3" Cat-Back Exhaust.

    Calibration Required. Installation of these MBRP Long Tube Headers will require the use of a Handheld Tuner to reprogram your Mustang's computer (ECU) for proper operation. By reprogramming the ECU, you will be able to realize the full power potential that these Long Tube Headers have to offer.

    Application. This 1-7/8" x 3" Long Tube Header and Off-Road Mid-Pipe Kit is specifically designed to fit left hand drive 2015 to 2019 GT Mustangs and are intended to be installed with MBRP's 3" Street or Race Cat-Back Exhaust System.

    Not compatible with the factory cat-back exhaust or right hand drive vehicles.

    Technical Note. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

    Application Notes. For 2019 Ford Mustang GT models ONLY, a Ford Front Driver Side Oxygen Sensor will be needed to complete installation. This sensor is of longer length, you can easily use that sensor as a substitution for the shorter OE passenger side oxygen sensor during installation.

    5 Top Rated Questions

    I have both mbrp headers and race cat backs, will I have to do any cutting to the pipes or will everything bolt up easily?

    • The MBRP Long Tube Header and Off-Road Mid-Pipe Kit is made to bolt up to 15-17 GT mustangs.

    Is there a significant difference in power between the off road version and the cat version? Thanks.

    • There would be a difference in power between the off-roadand catted headers, however, it would not be a significant difference where you would be able to feel it. Sound-wise, there is a difference there, where you would be able to hear it.

    Since my MBRP Race catback has a 2.5in step down, does that mean I have to cut and weld the catback with the mid pipe adapter in order to have a full 3in system?

    • The MBRP 1-7/8 in. Long Tube Header & Off-Road Mid-Pipe Kit will require the 3" cat-back for a bolt-on installation. We suggest taking the headers and cat-back to a shop to see what needs to be done for a proper install.

    Does it come with gaskets

    • The MBRP 1-7/8 in. Long Tube Header & Off-Road Mid-Pipe Kit does not come with gaskets. It will reuse the OEM manifold gaskets.

    How significant is the drivers compartment noise with Off-Road vs. Catted mid pipe kit? I'm already running a MBRP street series cat-back system. I've been waiting for the catted version to come back in stock but the longer I wait the more I just want to get the off road.

    • There will be minimal differences in in cabin exhaust volume between the catted and off road versions of the MBRP Long Tube Header and Mid-Pipe Kit.

      Amazing sound

      I put these on in my garage on a set of jack stands, it wasn't as bad as what I've read, really the hardest part is getting everything out of the way. I matched these up with the mbrp race cat back system that was already on the car. And wow, the increase in volume is crazy. I'm so happy with how these turned out. It's a very loud and very throaty note.

      Full 3" MBRP exhaust

      This takes the better part of 2 days to install on jack stands by yourself. One header bolt I had to use 30" of extensions with a crows foot to turn it at all! Everything fit extremely well, nice welds, fit up with my MBRP race exhaust easy after cutting the 2.5" factory step off... sounds insane, love it! Though I wish they made an X-pipe version in the cat-back kits.

      MBRP longtube offroad headers 1 7/8 ×3

      Very pleased with these headers. Quality and fit and finish top notch. Paired with corsa sport catback for an unbelievable sound. Never had car dynoed but paired with my other mods airaid intake,corsa sport catback and bama tuner this car is a beast. Good luck getting any traction with the stock Pirelli tires stock performance pack.
