    Review & Installation Video

    Hey, guys, Stephanie with AmericanMuscle.com here with my review of the BBK off-road shorty X-pipe available for BBK long tube header equipped 1996 to 2004 4.6 liter Mustangs. This one's pretty easy as far as who it's going to be for. The shorty X-pipe is going to be for the GT Mustang owners that plan on using BBK's long tube headers. Whenever you go from a shorty or factory header setup to a long tube, you're going to need to change your midpipe to a shorty midpipe. There are a few different options out there, but the general rule of thumb tends to be that you should not mix brands. If you want BBK's long tubes, you should stick with a BBK midpipe. Long tubes and a shorty midpipe go hand in hand since you need one to install the other. Usually, those installing long tubes are looking for power gains and an improvement in sound as well. Long tubes and a shorty midpipe have a different iconic sound that's hard to ignore. Along the lines of gains, long tubes and a shorty midpipe usually give mid-range to top end gains generally speaking. You may not necessarily be installing long tubes and a shorty midpipe for sound, but you are going to get a huge change in sound. The long tubes alone are going to change the sound of your exhaust. When you combine that with changing the midpipe, you can expect a pretty big difference in sound here and you're looking at a brand new sounding Pony when you're done. Looking more at the midpipe itself, we're looking at a two and a half inch midpipe that's going to work with the BBK headers. The X-pipe is mandrel bent which is typical in exhaust parts because the purpose of mandrel bending is to deliver smooth airflow. The smoother the pipe is the smoother the air will flow which helps with the velocity. There are a few different types of materials that exhaust components are made out of. The material of the midpipe is really going to drive the price point. This midpipe is aluminized tubing, and that's what helps to keep the BBK components more price friendly than some of the other options that are out there. Aluminized tubing has some upsides and some downsides as well. Like I already said, this type of material is going to be a more budget-friendly type of material. The sacrifice that you make here, however, is that the metal is prone to rust and have corrosion over time, especially if it sees harsh road conditions. If you live on the west coast or your car isn't a daily then it's not going to be a big deal to you. If you're looking for a ride or die system that's going to hold up and be everlasting over years and years then you're better off shopping for a 304 stainless steel system instead. This is an off-road X-pipe, meaning that it has no cats. Normally, an X-pipe is going to give more of a louder, raspier sound as opposed to the deeper note of an H-pipe. Being catless means this X will flow more than a factory midpipe would for sure and even more than a high flow cat would. BBK does offer this same midpipe with high flow cats if you want to keep some form of cats, but it is going to cost more, and I am going to say that it has high flow race cats. That means that it might not pass emissions, they may not be legal, and there's always that chance of a check engine light. Speaking of the check engine light, when you switch over to running long tubes you will need a tune. A tune here will not only help you get everything out of these expensive mods, but one of the main purposes of a tune with long tubes is to turn off the rear O2 sensor so you won't be getting a check engine light. Circling back around to price, you're looking at spending just under $200 for this X-pipe right here. Like I mentioned earlier, there is the catted version. I will point out that catted midpipes or catted pieces of exhaust, in general, are going to cost more than an off-road version will. BBK's catted version costs more than double this off-road version does, putting the price tag on that midpipe at over $400. Also, keep in mind that you won't be running this midpipe without a set of BBK's long tubes, so you can factor those into the price of the shorty X-pipe. These items go hand in hand since you can't really install one without the other, which is another reason why long tube headers are pretty much an investment. At the end of the day, you're looking at both power and sound gains here. Keep in mind that your gains will change depending on your setup and tune. In addition to that, you're also going to get an awesome change to your exhaust tone. The install of the X-pipe alone is not difficult at all. It's just a basic midpipe swap that doesn't involve removing any other items or any cutting. Since you'll most likely be installing this along with those BBK long tube headers, you can expect a project. Because of the combo install, you can expect a full three out of three wrenches on this one and a full day in the garage if you do decide to tackle this yourself. If you don't have a helping hand or you don't have much experience in this area, it might be better to just take the car to a shop for the install. If you do tackle this yourself, just know that you can do it on a jack and stands, but a lift would make it easier for sure. Like I said before, the midpipe is easy enough to install. The difficult part will be installing the headers. You're going to need your toolbox for the install with an assortment of different sockets, wrenches, and extensions. A lot of this install obviously requires working in some pretty tight areas. While everything is straightforward, getting access and maneuverability in these areas is actually tricky. Having a helping hand, in this case, is really going to benefit you. It is a lot of work, but at the end of the day, I think it's all worth it. Wrapping this up here, the BBK shorty X-pipe is going to be a must-have for anyone with a 4.6 liter Mustang that's looking at running BBK's long tube headers. It's an off-road aluminized steel X-pipe. As always, I suggest you check it out more online for yourself. I'm Stephanie, and for all things Mustang keep it right here at AmericanMuscle.com.

      Healthy growl

      Paired with the long tube headers and a decent catback, the sound of the car at high rpms changed dramatically with a healthy growl with the perfect amount of rasp

      Great product but would not work on my application

      I have Hooker Super Comp longtubes on a 2003 Mach and this x pipe would not line up with the headers at all. I’m sure if I had bbk longtubes, this product would be great. I have a hooker o/r x pipe that somebody added cats to so I will just have to make my x pipe an off-road x pipe the old fashioned way. I have slp loudmouth 1 rezzies on my factory catback also.

    Will it ONLY fit BBK LTs? I have MAC LT's and a Prochamber currently. Thinking about swapping to an X pipe for a bit and seeing the difference, but want to make sure they will fit. Thanks Justin.

    • No, it will not fit. I have the same set up as you do. I bought the BBK off road and when I tried to install it with my mac LTs it didn't fit. You can get them to fit but some cutting and welding to the x-pipe will be need it. Thank you! Lino.

    Will this X-Pipe bolt up to the stock exhaust? from X-Pipe to rear of vehicle?

    • This will require long tube headers for the installation.

    Will I need the 02 sensor extension kit or is it possible to make the x pipe work without the extension kit?

    • In most cases yes, you would require something like our SR Performance O2 Sensor Extension Kit, item # 56013, https://www.americanmuscle.com/bbk-o2-extension-harnesses.htmlbecause the rear O2 bungs on the BBK Off-Road X-pipe are placed further back.

    I have a set of DNA longtubes and was wondering, would this x pipe would fit on those headers?

    • The BBK Off-Road X-Pipe would be meant to be used with the BBK long tube headers for proper fitment. When doing long tube headers you will want to match the same brand header as mid-pipe to stay clear of any fitment issues with the two brands.

    if my cobra has BBK long tubes do I still need an exhaust flange gasket to put in between my bbk mid pipe and bbk header or is it only needed for the stock headers? My cars had an exhaust leak since I bought it and it throws a P0174 code bank 2 system lean because of it :( Im trying to figure out how to seal the gap between the header and the mipipe the flanges are rounded so a conventional gasket I dont think will work

    • The BBK Off-Road X-Pipe and Long tube headers will use ball and socket flanges that do not require a gasket. The two bolts on the flange should be tightened, alternating between them, to evenly pull the flange together for a perfect seal. If a leak persists, you may want to add a small amount of silicone exhaust sealant to the flange, though this may not be required.
