    Hey, everybody. I'm Justin with americanmuscle.com. And this is my quick review of the BBK three inch long tube header adapter mid-pipe, available in either catted or off road configurations fitting your BBK header equipped 2015 and up GT. So drilling down who this kit is going to be for is actually pretty simple, guys. This mid-pipe is going to be for anybody who is either planning on purchasing or already purchased a set of BBK long tube headers, and needs the mid-pipe to complete the package. Now most aftermarket header companies will actually include the mid-pipe along with the header in one complete package. But what BBK has done is actually split this thing into two categories. You have the long tube itself along with the mid-pipe. And that's because BBK gives you so many options when it comes to choosing the right header for your setup. For instance, you're going to be looking at a ceramic versus a chrome option. A one and three-quarter versus a one and seven-eighths inch option. And then finally, a catted versus an off road option. I like this because it allows you to essentially build or create your perfect long tube setup, and still have it be one of the most affordable on the site. More on the price later, but let's first talk about the specifics of this kit. Again, guys, you do have two options when picking up this mid-pipe from BBK. We do have a catted version shown here. Going to include these two high flow cats. Will add a little bit more to the final price tag. In addition to that, they do of course, offer your off road version here. No cats anywhere to be found, and this is typically going to yield the biggest power and sound gains. Both options are going to be constructed from three inch mandrel bent aluminized steel tubing. Both options will include the two and a half inch factory style connect here, which will work with your factory exhaust in addition to most aftermarket catbacks. Along with that, BBK has included two pre-welded O2 bungs, in addition to the flanges and clamps needed for the installation. So the catted version will be the more expensive of the two, coming in around the $400 mark. And that's pretty typical whenever you compare a catted version to an off road version. Now the catted version will include these two high flow cats and will be slightly more appealing to those of you with stricter emissions rules. But as always, check with your local laws before ordering. Just some quick math here, guys. Again, the catted version around the $400 mark. You add in BBK's long tube headers, which range anywhere from $500 to $600. And you can essentially piece together your own catted long tube setup for around the $1000 mark. Maybe even a little south, which is by far and away going to be your most affordable option here at AM. The off road version, on the other hand, is going to be about half the price of the catted version. Just north of the $200 range, and will bring your all in total price for a long tube setup to just north of the $700 mark. Which should fit nicely into just about anybody's budget when it comes to shopping for long tubes. Now with all that said, guys, the quality of the BBK headers might not be as nice as some of your other options here on the site. And that's more me nitpicking material versus quality of the build. Now for instance, BBK utilizes a mild steel header along with an aluminized steel mid-pipe. Whereas most, if not all of your other options on the site will utilize some sort of 304 grade stainless steel throughout, which is just a superior metal. Really not going to affect your performance per se, but it is worth pointing out. Materials aside, the construction is very solid with the BBK headers. A nice mix of machine and hand welding, they're all pressure tested for a leak free operation. And they're all made in the USA. Since you'll most likely be installing the mid-pipe along with your BBK long tube headers, figure a full three out of three wrenches on the difficulty meter. As long tube header installs are typically going to be a chore. You're going to want to leave yourself at least a full day in the garage, maybe two to get this one done. So set aside a weekend. Make sure you have a solid set of tools on hand. But if all this sounds like it's going to be a little too much of a hassle for you, don't be afraid to leave this one up to your local shop. So to wrap this one up, guys, if you plan on getting a set of BBK long tube headers for your Coyote powered S550 GT, you're going to need one of these mid-pipes to complete the package. Whether you go catted or off road, I think you'll find the BBK options will be one of the most affordable on the market. And you can grab yours right here at americanmuscle.com.

    Required For BBK Long Tube Headers. When upgrading to a set of BBK long tube headers on your coyote powered S550 Mustang you will require a 3" to 2.5" Mid-Pipe Adapter for proper installation. This Mid Pipe adapter along with BBK Long Tube Headers will allow you the option of installing a factory catback, a BBK 2.5" catback or any other brand of 2.5" aftermarket catback on your S550 GT.

    Durable BBK Construction. Manufactured from high quality 3" diameter aluminized tubing for superior strength and corrosion resistance, this BBK Long Tube Header Adapter Mid-Pipe features smooth mandrel bends throughout the entire piping to improve exhaust flow for more power and better performance.

    Application. The BBK Performance 3" Off-Road Long Tube Header Adapter Mid-Pipe is specifically designed to be used on 2015-2017 GT Mustangs equipped with BBK's Long Tube Headers and allows for the use of your stock OEM catback, a BBK 2.5" catback or any other brand of 2.5" aftermarket catback designed to fit the 2015-2017 GT Mustang.

    Technical Note: This BBK product is intended for off road use, and is not legal for use in emission restrictive states.

    I have an Awe cat back track exhaust with the h pipe. Will this adapter work? Im not sure if the mid pipe for my exhaust is full 3 inches or a step down 2.5 I have been getting mixed answers.

    • The H pipe would work with this adapter as it steps up from the factory 2.5" connection.

    I have the sr x pipe and Flowmaster outlaws! Would the BBK 1 7/8 headers and this mid pipe work with those? If not which headers and mid pipe would you recommend?

    • The BBK 3 in. Long Tube Header Adapter Mid Pipe and long tube headers will work with the Outlaw exhaust yes! As far the SR x-pipe this would be replaced with the long tube headers and adapter.

    I have a 2017gt with roush X-pipe and stock manifolds. If I put the 1-3/4 bbk long tube header with this adapter mid pipe, will they connect to the x pipe or do I need to buy another x pipe that fit with this adapter?

    • Your Roush X-pipe would connect to these BBK long tube mid-pipe adapters.

    Would you be able to mount this on kooks 1-7/8" long tube headers?

      Midpipe

      Received in working condition and work well. Downfall, everything I keep receiving from bbk has little or a bunch of rust. Even my longtube headers I purchased with these had it.

      Smell the fumes

      It's a easy instalment if you are connecting it to your factory exhaust but if not make sure it fits first. I have a corsa extreme and it won't directly fit with it, I had to have it welded but no big deal. If you don't tho k you can handle the smell don't get the off road pipes. The smell is pretty strong but I love the smell of gas. And nothing is like a fully open exhaust my stang can finally breath

      Easy Install, BBK LTH connected to MBRP Cat-back

      I used this adapter to connect my BBK 1 3/4" LTH to a MBRP Race Series Cat-back exhaust system. This product was very easy to install (specially after installing the headers) and fit well. I wouldn't say they fit perfectly but they fit about as well as you could expect. I put these on with the pipes assembled but all the bolts loose and then bolted it up, starting at the header, seemed to make the alignment of the exhaust work better. I have had these on for about 2 weeks now and have had no issues. I drove my car around a little before I received a Rev-X Tuner and it didn't seem to run quit right. Also my car had a couple codes because of no longer having Cats. I'm running a 91 Race tune from Bama and my car is a new beast. HP gains are VERY noticeable. My car sounds amazing, made my idle deeper and my car sounds like a dragster when I push the pedal to the floor.

      Solid product

      Overall BBK has produced yet another solid product that functions well. The only issue I ran into is the clamps provided don't clamp quite tight enough to completely seal the joint between the two pipes. I solved this problem by simply welding the two together once I had everything in place.
