Review & Installation Video

Review & Install Video

Hey, everybody. I'm Justin with and this is going to be my quick overview of the BBK Off-Road Shorty H-pipe available for your 2015 and up V6 Mustang equipped with BBK long tube headers. In this video, I'm going to talk to you about some of the basic benefits you can expect when checking out the off-road H-pipe from BBK, what you're going to be looking at as far as materials and construction and then finally a quick little walkthrough of the install itself. And because you need to install this with a set of long tube headers, I'm going to go ahead and knock it up to a full three out of three wrenches on the difficulty meter, and I will expand on that later on. Plain and simple guys, this off-road H-pipe from BBK is going to be for the newer 3.7-Liter V6 owners out there who have already installed or are planning on installing a set of long tube headers also from BBK and therefore need a mid-pipe solution. Now, this particular pipe is going to be of the off-road variety, meaning that they're not going to be any cats anywhere on this pipe here, making for the biggest power and sound gains over the factory mid-pipe. It's also going to feature the very popular H-pipe configuration, which will round out the sound a little bit, keep the tone a little lower and the volume down overall compared to that of an X-pipe. So, with all that said guys, let's take a closer look at the BBK Shorty. Now, BBK is a company that really needs no introduction, especially if you've been into Mustangs for any length of time. They've been a solid ally in the quest for more horsepower ever since the Fox Body days back in the '80s of course, and this is really what they do well. This is a part of what they've been doing since day one and as such, it's going to be a great fitting, affordable solution that will get the job done. First and foremost here, let's get the obvious out of the way and that is the fact that it is a shorty mid-pipe design, meaning it's only going to work with your long tube headers, more specifically BBK's long tube headers, chrome or ceramic that really doesn't matter. If you wanted to add a mid-pipe to your stock manifold or maybe an aftermarket shorty header car, well, this is not going to work. Instead, you're going to need a stock length mid-pipe, there are a few other aftermarket solutions available here on this site if that's what you're looking at. But getting back to this particular mid-pipe that we have in this video again guys, this is an off-road H-pipe. That off-road simply means there are no cats anywhere to be found with this particular option. If you're unable to run something like this on your particular Mustang, BBK does make a catted version of the H-pipe, which you can grab here on the site as well. It's going to add to the price a little bit, will help keep the sound levels down but shouldn't make a huge difference overall. In addition to being an off-road mid-pipe, the other big thing you need to know here with the BBK option is that it features the H-style crossover pipe. Now, the general rule of thumb with the H-pipes here guys is that you're going to get a slightly deeper tone overall, going to keep the volume levels down ever so slightly, and it's going to deliver a slightly bigger, low-end gains. Now, your other alternative is to check out an X-pipe of course, that's going to deliver a louder, more raspy note of course, and slightly bigger top end gains. Ultimately in my opinion, the 37 is a slightly raspy motor from the factory, so I think the H-pipe does a great job of kind of rounding the tone out even without the cats in place. With the sound pretty much wrapped up guys, let's move into construction and materials a little bit, and BBK as a whole does a great job when it comes to their products. I've toured the facilities, they take great pride in their work. The materials could be a little bit nicer but the flip side of that argument is that the stuff is all very affordable. Obviously, you're not getting premium grade 304 here with this product, but instead, you're getting that aluminized steel, an entry-level material but as such, you're getting an entry-level price here, right around 200 bucks is what you're going to be dropping on this particular mid-pipe. Pair that BBK's equally affordable long tube headers and you have one of the most affordable complete long tube setups available in the aftermarket for your V6. Going a little further with the construction, you're going to find two-and-a-half-inch diameter mandrel bent tubing here for the most part guys, we're also going to find pretty solid welds overall, the included O2 bunks preloaded for you, new flanges of course and the stepdown, which does allow this mid-pipe to be used either with your factory cat-back or an aftermarket cat-back that does utilize the factory style connection. Switching gears, let's talk install, and like I mentioned at the top of this video here guys, the reality is you're going to be doing this with a set of long tubes. Now, honestly, the mid-pipe by itself isn't all that bad. You got a couple of bolts down here at the flange and your exhaust clamps connecting this thing to your aftermarket or factory cat-back. But again, the reality is you're going to be installing this the same time as those long tubes from BBK, so for that, we're going to stretch this one out to a full three out of three wrenches on the difficulty meter and at least a full day in the shop or garage, get everything knocked out. Long tube headers are no joke here guys, so as such, just be prepared for a tough install and one that's going to require a lot of tools. However, if you just simply need to replace the mid-pipe for whatever reason, again, a much easier install and maybe an hour or two from start to finish. Wrapping this one up here guys, the BKK off-road H-pipe is a great and affordable choice for the V6 owners out there looking for the maximum gains possible when doing a long tube install, but maybe would prefer to keep some of the sound and rasp to a minimum that otherwise comes along with those X-pipes. So, that's my review of the H-pipe from BBK, which you can grab right here at

Overall Performance Increased. If you're planning on installing a set of BBK Long Tube Headers to your 3.7L S550 Mustang, unfortunately the factory Mid Pipe cannot be used with those headers. That is where BBK steps in with their Off-Road H-Pipe. This H-Pipe is specifically designed to be used with their Long Tube Headers so you can complete your install. The BBK H-Pipe also features a merged step down that allows you to use the Mid Pipe with a factory or aftermarket cat-back exhaust utilizing the factory connection. After installing this H-Pipe on your V6, you'll improve your exhaust flow which results in an increase in horsepower and torque. On top of it all, due to the "H" pipe design, it will also add an aggressive sound to your exhaust.

Durable Construction. BBK manufacturers this Off-Road H-Pipe from quality free-flowing 2.5" diameter aluminized tubing for superior strength and corrosion resistance. This H-Pipe features smooth mandrel bends throughout the entire piping, to improve exhaust flow for more power and better performance.

Application. This BBK Shorty Off-Road H-Pipe is specifically designed to fit the 2015 to 2017 3.7L V6 Mustangs equipped with BBK Long Tube Headers.

Technical Note. This BBK Mid-Pipe is intended for off road use, and is not legal for use in emission restrictive states.

I just installed this with my bbk long tube headers and I connected the front pair with the extension but I don't know how to connect the rear pair. Do I need some kind of rear extension or should the rear 02 fit into the harness?


Would this H pipe and the long tube headers pass emissions in Cobb County,Georgia (30060) with it having no catalytic converter on the pipe?


  • It would be best recommended to contact a local shop that performs emissions testing in that state to accurately depict whether or not this would be legal for use in your state and county.

So you can't just buy the H pipe and put it on? You have to get the long tube headers to?


  • This H-pipe is designed to be used in unison with long tube headers as this piece will connect directly to the long tube header collector.

Would this H-Pipe work with the Borla Stinger S-Type exhaust??


  • The BBK Shorty Off-Road H-Pipe is designed to be used with BBK Long tube headers. This would bolt up to the Borla Catback when used with the BBK long tubes.

    Love it. Recently installed the off-road H-pipe with BBKs longtube headers and Flowmaster outlaw axle-backs with a roush cold air intake. Very deep aggressive tone with this set up not raspy at all until you reach about 4000 RPMs. First time I started it up at a parking lot after sitting for about 2 hours (parked in the very back of the lot) a truck 3 spots over alarm went off and I couldn't help but laugh. By far will bring smiles per gallon.

    I was originally going to go with an off road X pipe but decided it may be too raspy with my setup along with the already raspy motor the 3.7 is so I went with the H pipe. These have to be installed with bbk's Longtube Headers just to clarify. I love this combination. The H hipe gives it an old muscle car grumble!!! Just what I was looking for.

    Great product. Cracks when you give it gas but doesn't have any drone so it balances out nicely. Would definitely recommend with the bbk LT headers you get one MEAN NOTE. If your worried about it being raspy it's not at all. I even got muffler delete and it's not so all in all great product. They sent the wrong rear extensions so just be carefull but otherwise it was all great.
