Review & Install Video

Hey, guys, Stephanie with AmericanMuscle.com, here with my review of the BBK shorty Catted X-pipe, available for BBK long-tube header equipped 2005 to 2010 GT Mustangs. So, this one's pretty easy as far as who it's going to be for. The shorty X-pipe is gonna be for the GT Mustang owners out there 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 mid-pipe to a shorty mid-pipe. Now, there are a few options out there, but the general rule of thumb tends to be that you should not mix brands. If you want BBK long-tubes, you should stick with BBK's mid-pipe. Long-tubes and the shorty mid-pipe go hand in hand since you need one to install the other, and usually, those installing long-tubes are looking for power gains and an improvement in sound as well. Long-tubes and a short mid-pipe have a different iconic type of sound that's hard to ignore. And along the lines of gains, long-tubes and a short mid-pipe usually get mid-range to the top end gains, generally speaking. And you may not necessarily be installing long-tubes and a shorty mid-pipe for sound, but you are going to get a huge change in sound. Long-tubes alone are going to change the sound of your exhaust, and when you combine that with change in the mid-pipe, you can expect a pretty big difference in sound here and you're looking at a brand new sounding component when you're done. But looking more at the mid-pipe itself, we're looking at a two and three-quarter inch mid-pipe that's gonna work with the BBK headers. The X-pipe is [inaudible 00:01:17] bent, which is typical in exhaust, but the purpose of [inaudible 00:01:20] bending here 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 this mid-pipe is going to really drive the price point. The 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 going to 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're low on the west coast or your car [inaudible 00:01:55], then it's not gonna be a big deal to you. If you're looking for a ride or die system that's gonna hold up and be everlasting over years and years, then you're better off shopping for a 304 stainless steel system instead. This is a 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 cats are high-flow race cats, so they're gonna flow more than a factory cat would, for sure. But I'm gonna hit again that these are high-flow race cats. That means they might not pass emissions, they might not be legal, and there's always that chance of a check engine light. But speaking of the check engine light, when you switch over to running a long-tube setup, 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 the tune, along with the long-tube headers, is to turn off the rear O2 sensors so that you won't be getting a check engine light. Circling back around a price, you're looking at spending just over $400 for this X-pipe right there. I will point out that Catted mid-pipes or Catted pieces of exhaust in general are gonna cost more than off-road version will. BBK does have an off-road version of this mid-pipe, which is gonna be this same thing just without cats, and that's gonna cost a little bit more than $150 less. So that's always an option. Also keep in mind that you won't be running this mid-pipe without a set of BBK's long tubes, so you can factor those into the price of the shorty X-pipe. These [inaudible 00:03:07] 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. So, 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. And in addition to that, you're also gonna get an awesome change to your exhaust tune. The install of the X-pipe alone is not difficult at all. It's just a basic mid-pipe swap that doesn't involve removing any other items or any cutting. But 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 don't have much experience in this area, it might be better just to 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 stand, but a lift would make it easier, for sure. Like I said before, the mid-pipe is easy enough to install. The difficult part would be installing the headers. You're gonna need your toolbox for the install, along with an assortment of different sockets, wrenches, and extensions. You're looking at things like disconnecting the steering shaft, removing the motor mounds, and dropping the cross member. 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. Having a helping hand in this case is really gonna benefit you. But at the end of the day, I think it's all worth it. So, wrapping this up here, the BBK shorty X-pipe is gonna be a must have for anyone with a GT Mustang that's looking at running BBK's long-tube headers. It's an aluminized steel X-pipe that comes with high flow race cats, and your rear O2 extensions as well. 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 AmericanMuscle.com.

Im ordering BBKs Longtube headers and catted x pipe, i already have pypes electric cutouts from AM and am wondering if there is enough room in between the cats and flange to the headers to fit the cutouts in that place?

Bborbaa

  • If you have the cutouts right after your cats, you would have to do some modifications if you would like to keep them between the mid pipe and the headers. The addition of headers and the shorter mid pipe change up the geometry of your exhaust, so the modification would be to compensate for that change. If you take a look at the customer photos presented with the cutouts there are some creative examples of different ways to make them fit as well. I will post a link to the product page below: https://www.americanmuscle.com/pypes-electric-exhaust-cutout.html

Is it possible to use the long tube headers and x-pipe with the stock GT mufflers? Looking for a little rumble, but don't need it to be obnoxious.

Brendon

  • Purchasing and installing the BBK Catted X-Pipe (05-10 GT w/ Long Tube Headers) and matching BBK long tube headers will be able to be used with the stock mufflers.

Will this go with my mac longtube headers?

kumar

  • The BBK Catted X-Pipe (05-10 GT w/ Long Tube Headers) will not work with the Mac long tubes. When doing long tube headers you want to match up the same brand mid-pipe as the header for proper fitment.

Can I use these with the pacesetter long tube headers and pypes violators mufflers?

Jake

  • When it comes to long tube headers we typically say to stay same brand between the mid pipe and the headers just because manufacturers design them specifically for each other. So if you tried to do anything other than a BBK long tube with the BBK Catted X-Pipe (05-10 GT w/ Long Tube Headers) you would most likely need to do some modifications. However, when it comes to the muffler, you can do whatever muffler you want, the muffler is not held back by the mid pipe or the headers.

Axel back or Cat back exhaust. Will both Axel back or Cat back exhaust work with this? Im just wondering if a muffler shop would be able to weld some pipe to make it fit. Or would that not be optimal?

Kemjo

  • Yes this can be made to work with either and the right muffler shop can weld whatever you need. Most companies however make sure their parts align perfectly so going with one company for your whole exhaust setup is never a bad idea

    Oddly Didn't Fit, but Works Great

    I got the x-pipe from AmericanMuscle and the headers from another source, both meant for the 05-09 Mustang GT. After having a shop put the headers in, they found that the x-pipe had a larger flange that wouldn't allow it to bolt to the headers. The x-pipe doesn't look like the picture shown above, but what got me personally was that both products were meant to work with each other but didn't. I ended up calling AmericanMuscle, and they helped me through the process of having this problem fixed up. It ended up taking 5 days to get everything fixed/installed. All in all, the x-pipe and headers really brought out a sound I wasn't expecting. I've gotten compliments ranging from "sounds like an angry bear" to "this is what a real modern muscle car should sound like". Thanks for all the help AmericanMuscle!

    BBK Catted X-Pipe 05-09 Mustang GT

    I live in MIssouri and AmericanMuscle got this to me in 3 days. Free and super fast shipping, is there anything better? The install was pretty easy, of course, you need the BBK longtube headers and these will match up 100% it took a little over an hour to install the x-pipe and the included O2 extensions. And I did it by myself on jack stands. I noticed some differences, the sound... oh the sound! It gave my stang a whole new rumble (get rid of those huge ugly stock cats) and I got roughly 12hp gain on the dyno after the install. These were a perfect fit for my fully aftermarket exhaust (Longtube Headers, x-pipe, mandrel bent mid-pipes, and an axle-back)

    Garbage

    Shortly after installing these my car threw a code for the passenger cats not running efficiently. The shop that installed these and the dyno company both said the cat was defective and bbk kept giving me the run around and repeating things I already had answered to. Then they stopped emailing me back in a pathetic attempt to get rid of me. It took calling American muscle just to get an exchange. I highly recommend you avoid BBK as they make extremely cheap parts and have horrible customer service. This isn't the only bbk part that I have got that was defective.

    Needs better quality control

    Made this pipe fit by heating and bending tubes because it was too narrow to fit up to the BBK long tubes. The rear of the pipe was also slightly bent down on one side but I managed to slide it into tailpipe by opening up the sleeves completely. Also had to cut off the hangers as they aren't used on my car. Also doesn't seem to fit with my Moroso driveshaft loop. Soundwise it sounds good not crazy, works well enough for me at this point.

    I like everything except the fact that the one pipe is pointing down where it meets the tail pipe section. One is nice and straight the other points down which makes the muffler point up some, have to try and make some adjustments.

    VERY disappointed. Needs expensive modifications.

    This midpipe was nearly 1.5" too narrow to align with the expensive BBK headers sold with it. The hanging brackets also had to be moved to go into the stock mounts. Since I had a pro shop doing the installation, it cost me several hundred dollars more than quoted. BBK products will not be purchased by me again.

    needed piece to have with headers

    Bought this to go along with my bbk long tubes. got cats because of inspection and I have neighbors, so I wanted it to be a tad quieter. I'll be honest, these cats are that much quieter compared to no cats at all, but still sounds great!Tthe whole x pipe is very well made, went on fairly easy, had to kinda stretch it onto the headers to get them on, so everything is nice and tight. I only wrote full day for installation because it was part of the header install, realistically an xpipe only takes about an hour or so. Great product, good sound, good price! Cant beat it
