Review & Installation Video

Review & Install Video

Hey, guys, Stephanie with americanmuscle.com, here with a review of these MBRP Long Tube Catted Headers, available for 2015 and up, S550 GT Mustangs. In this video, we're gonna be looking at a few different things in regards to these headers. We're gonna be talking about the materials of construction of the headers themselves, and the install too. We'll talk more about this later, but I can tell you right now, the 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. The MBRP Catted Long Tube Headers are gonna be a good option for someone looking for a natural finish long tube, that's gonna maintain the use of cats [SP], and make way for a three-inch aftermarket catback. The connection pipes that come with these headers are three-inch catted pipes, which means that you'll need a three-inch catback. 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 set up. The runners on these particular headers are one and seven-eighth inch, which is slightly different than the one and three-quarter inch offering. Traditionally, you see forced induction cars running the larger runners, and then [inaudible 00:01:03] cars running the smaller runner, but I wouldn't really say that that's a hard and fast rule, especially with the new Coyotes. So, you don't have to have a blower to run the larger diameter like these headers here, 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 have. If you have some bolt-ons and you're there still NA, you might see a hit on your low end torque, but once you spin the coyote motor up, the larger diameter is gonna help keep things moving. So, what you're gonna see are top endings. 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 don't have a ceramic coating either, they are made from that 304 stainless steel tubing, so you won't have to worry about corrosion. Not to mention you get to see the beautiful welds since it's had that raw finish. And this is mandrel bent tubing, which is gonna help with smoother air delivery. The primary tubes then merge down to a three-inch collector, and MBRP has these header flanges up there that are laser cut and they do that to prevent leaks and create a good fit. Then you have your connection pipes here. Like I said earlier, they're three-inch and they are catted. These are high fluid race cats and require a three-inch catback to be bolted up to them. And if you didn't know already, when you change your header set up to a long tube set up, you also need to change your mid-pipe to a shorty mid-pipe, in order to work with the long tubes. So just keep that three-inch requirement in mind when you're trying to pick out your catback, 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, 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 inch option that we have here, is 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. Either way, you're looking at spending between $1,300 and $1,400 for a set of these. But do keep in mind that you still need a shorty mid-pipe in order to install these, so you can figure on purchasing that as well. And that's why I called long tube headers an investment earlier. But you do have to keep in mind all the benefits and power that you'll be getting from this set up, and to put things in perspective, it's not just MBRP that's gonna be expensive. You're gonna be looking at headers costing over a grand anyways no matter what brand you go with. As for the install on this one, long tubes are always gonna 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 just to 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 catback with these headers. You can do it on a jack and jack stands, but a lift would make it easier, for sure. You're gonna need your toolbox for this one, [inaudible 00:03:54] 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 obviously 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 a little bit more room. And having a helping hand in this case is really gonna benefit you. But a day of wrestling and some pretty penny spent on this mod is totally worth it, in my opinion. So, wrapping things up with the MBRP Long Tube Catted Headers, these are 304 stainless steel headers with high floor race cats. They have one and seven-eighths inch runners, and a three-inch collector that runs down into three-inch collection pipes. Need a three-inch catback to pair with these headers, and as usual, you can check them out more online for yourself right here, at americanmuscle.com.

Ask a Question

Will these headers fit the stock set up, and what would the horsepower/torque gains be more or less???


  • These headers will not fit the stock setup as they require at least a 3" catback exhaust system for proper fitment, the horsepower and torque would also be increased with this up to 20-30 hp and torque.

In the video it states that you have to purchase a shorty mid pipe in order to install these headers with your 3" cat back. I have the mbrp street 3" cat already installed with an h pipe. Would I still need to replace that with a shorter mid-pipe? Or will this application work with my current set up?


  • The MBRP 1-7/8 x 3 in. Long Tube Catted Headers will bolt directly to your MBRP's 3" Street Catback exhaust with no additional components required

What tune would you need?


  • The MBRP 1-7/8 x 3 in. Long Tube Catted Headers can use any one of our tuners on the website to account for the added amount of flow that will be leaving the engine.


Helpful (0)

Will these headers (in conjunction with the MBRP Race Catbacks) be emissions compliant in Texas?


  • Hey Newbie, Unfortunately the DOT compliance changes from state to state. So it would have to be something you check with your local shop that dos emissions inspections.

How loud will these headers be combined with the mbrp race cat back


  • When combining the MBRP Long Tube Catted Headers and the MBRP Race Cat-Back Exhaust the exhaust will be on the louder side due to the high flow cats, free flowing mufflers, and long tube headers.

I've got the MBRP catback system installed already. With these headers would I need to buy a mid pipe still? Or would I be ok with just buying these

    Perfect Pair!!!

    Just mounted these headers to MBRP street series catback exhaust with h-pipe and they sound amazing. They were definitely made for each other. I get the extra horsepower and sound without being overly obnoxious while in my neighborhood. Had them installed by a shop and it only cost me $600. They said it was one of the easiest header installs they have done for the s550.

    Great fit sound performance

    Rear drivers side header bolt would have been nearly impossible to tighten except i had the transmission out. I think other brands have a little more clearance on this bolt Only complaint otherwise perfect fit.
