      Review & Installation Video

      Hey, guys, Stephanie with here with my review of the BBK Catted X-Pipe available for 2005 to 2010 GT Mustangs. In this video, we're gonna be talking about a few different things including the sound of this X-pipe, the materials and construction, and the install. I'll talk more about this later, but the install for this one is going to be a one out of three wrenches in the difficulty meter, since it's an easy install for anyone.This X-pipe from BBK is going to be for the GT Mustang owners out there that are looking for an affordable X-pipe that's going to maintain the use of cat and that's gonna give a loud and raspy exhaust mod. This X-pipe is gonna make a big difference over the stock H-pipe and it's also one of the most affordable X-pipe options out there. Looking more to the mid-pipe itself, we're looking at a 2¾ inch mid-pipe that's gonna work with the factory headers or a set of BBK Shorty headers. The X-pipe is manual bent which is typical in exhausts, but the purpose of manual bending is to deliver smooth airflow. The smoother the pipe is, the smoother the airflow will be which helps with velocity. Now, there are a few different types of materials that exhaust components are made out of, and the material of the mid-pipe is really gonna drive the price point. This mid-pipe 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. So, aluminized tubing has some upsides and some downsides as well. Like I already said, this type of material is gonna be more budget friendly. 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. But if you live on the West Coast, or your car isn't a daily, then it might not be a big deal to you. If you're looking for a rider-dice 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 catted X-pipe and normally an X-pipe is gonna give more of a louder raspier sound, as opposed to the deeper note of an H-pipe. The Cardster [SP] high-flow race cats so they're gonna flow more than the factory cats would for sure, but I'm gonna hit again that these are high-flow race cats, and that means they might not pass emissions, they might not be legal and there is always that chance of a check-engine light. Circling back around that price, you're looking at spending between $400 and $500 for this X-pipe right here. I will point out that catted mid-pipes or catted pieces of exhaust in general, are gonna cost more than off-road versions will. BBK does have an off-road version of this mid-pipe which is gonna be the same thing, just without the cats, and it's gonna cost a little more than $150 less, so, that's always an option. But at the end of the day, you're looking at both power and sound gains here, since the X-pipe will open up exhaust flow and net you a touch more horsepower and give you a change in sound as well. But just keep in mind that your gains will change depending on your setup and your tune. The install of the X-pipe is not difficult at all. It's just a basic mid-pipe swap that doesn't involve removing any other items or any cutting. You're looking at a one out of three wrenches in the difficulty meter and about an hour's time in the garage. If you don't have much experience in this area, it is a good idea to get a knowledgeable helping hand, but either way, this is a mod that most people, even first timers, can tackle themselves. 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 mid-pipe is easy enough to install. You need a few tools for the install, but at the end of the day, you're just looking at a few exhaust clamps here to get the factory mid-pipe out and the new one into place. You do have some pieces here with this X-pipe, so just make sure to hang everything loosely until you have the exhaust all lined up, and then tighten everything down. And don't forget that you should re-tighten everything once you're passing heat through the mid-pipe, just to make sure you won't have any exhaust leaks. Wrapping things up here, the BBK X-pipe is going to be a good option for anyone with a GT Mustang that's looking at running BBK Shorty headers or the factory headers. It's an aluminized steel X-pipe that comes with high flow race cats and, as always, you can check this mid-pipe out some more online for yourself. I'm Stephanie, and for all things Mustang, keep it right here at

        I added this set up to Ceramic Coated BBK Shorties and SLP loudmouth muffler deletes. I wasn't completely satisfied with how quite my 07 GTCS became after adding the BBK shorties so I figured an X with Hi-Flows would do the trick. Well it did and my GTCS is very loud. I am considering adding mufflers now to tame it down. Don't get me wrong it sounds amazing! This might not be loud to everyone but for me it is certainly comes close to crossing a line of awesome and irritating.

        Awesome x pipe!

        I absolutely love the x pipe!! Before I had an off road x pipe and it was louder and the smell really annoyed my neighbors. The cats on this BBK X pipe quite it down by about 20-30 and the smell is the same as stock. She’s got a new rumble around 1000-1700RPMs with some pops. There is a little bit of added drone around 2000RPMs but I got use to it quick. The fitment was great and all the sensors fit. No check engine light which I was really happy about. Can’t say enough how satisfied I am with this product.

        Exactly what I wanted

        Paired up with a muffler delete and it screams!!! Only con was the pipe was bent a little and didn’t fit exactly with the stock manifold but the right shop can put it on. I recommend trying this before you go catless

        I had to replace my BBK cats because I had a problem with my cam phasers and it resulted in clogged cats. So I decided to replace with the same style. They work as advertised so it was an easy choice. Good sound and flow.

        I think it made my car too loud!!

        I had muffler deletes on the stock system. It was loud but just not enough. While I had the cats off it was loud as heck because you know. I wanted to see the loudness. Lol I installed these and I swear it's still as loud. I haven't gotten to drive it yet but when it's at idle you really do need to talk louder for people to hear.

        BBK cats x pipe

        Good product. I have monzo shorty headers on the car and was worried they wouldnt fit but they did with no problem I also have a catback from magnaflow and it still fits. The xpipe was a little bigger but the clamps went on just fine with a few taps of a hammer and sealed up good. No leaks. And you dont need the 02 extensions to use these. It takes an afternoon to do these by yourself with jack and jack stands. But I'm also in a condo parking lot. Dont want to hit the car parked next to mine with some pipe haha. The exhaust seems more raspy.

      I have stock headers and fr500s axle back . I like the way it sounds, but looking for more sound! Where i live i cant do off road. Now, these catted bbk will keep the american muscle car tone and rumble , but its gonna be more louder,or the tone will change? And also after install i m gonna have check engine light ? I dont have a tuner and dont want one. Thanks!!

      • When you are swapping your stock mid-pipe for an aftermarket one, the sound will change especially with this mid-pipe since it is an X-pipe. This X-pipe will give you more of a raspy sound. So yes, your tone will slightly change as it will a more aggressive growl to your exhaust. Also, as you can see in the picture before and after the cats there are O2 bungs in which to plug in the O2 sensors. With the O2's properly installed into the bungs, you should not have a check engine light appear. This will also not cause you to have to re-tune your vehicle.

      Hi I'm looking to get a x pipe but I want to stay away from setting off my check engine light. I was wondering if this product tends to do that and if so what would you suggest doing to increase sound without having a check engine light. Thanks

      • Since this mid-pipe has the cats on it you will not run a check engine light and this would be a good way to help improve the volume of the car!
