Review & Install Video
Hey, everybody. I'm Justin with americanmuscle.com, and this is gonna be my detailed breakdown of the Pypes Off-Road Long Tube Headers featuring the 1 and 7/8th-inch primaries along with their 3-inch connection pipe. And it is available for your 2015 and newer Mustang GT. Now, in this overview, I plan on talking about some of the benefits of installing a long tube header like this onto your S550 GT. We'll talk about what you can expect from a material and a construction standpoint, where these guys will land on the price range, and then finally, a brief little overview of the installation. This is gonna be a full-pull three out of three wrenches on the difficulty scale for me because, honestly, long tube headers are going to be a tough job, and that certainly isn't gonna change here with the S550.So, the Pypes long tube headers that we have in this video should appeal to Coyote owners out there for a couple of different reasons. Now, first and foremost, these guys will feature the 1 and 7/8th-inch primary, making them a good choice for naturally aspirated applications, but an even better choice for forced-induction applications. Essentially, it's a best of both world type of diameter, something that will work for your bolt-ons but will really shine once you add in those big modifications. Secondly, this is important to point out because these long tubes will only work with a three-inch style connection catback, meaning your factory catback or an aftermarket catback with that neck down will not work with these particular long tubes, as they do feature that three-inch connection pipe. Last but most certainly not least, these guys should appeal to the S550 GT owners out there looking to grab a quality stainless steel header, 304 grade to be exact, but want to spend the least amount of money in the process.And sticking with that topic here guys, the Pypes brand as a whole typically will be a budget or value brand overall, but that doesn't necessarily mean your products are going to suffer. I've noticed that to be true especially with their newer S550 offerings. Their X and H box catbacks are really nice, 304-grade stainless steel. They are very affordable, and the same can be said with their long tube headers here. Better materials, better fitment, better welds, all things I've noticed with their newer generation products here. And at the same time, they are still super-affordable. In fact, you're looking at right around $900 bucks for these guys, again making them the most affordable full 304 stainless header on the site, and only slightly more expensive than the BBK options, which do utilize a mild steel.I do want to stick with the materials a little bit longer here because, again, you are looking at 304-grade stainless steel throughout. The benchmark material in the land of after-market exhaust systems and of course the stainless steel header systems that we're dealing with here today. You are getting some pretty solid welds, definitely better than some of the other products I've seen in the past. But at the same time, are you seeing the level of build or weld that you would with an American Racing, or a Cooks, for instance? Well, not exactly. But keep in mind guys, you are spending close to two G's for those products I just mentioned. You're only spending about $900 bucks here for the Pypes version, so eventually, something has to give. But again, that being said, these guys still will perform as advertised for that $900 price point.But moving away from the materials a little bit, I do want to talk about the design of the Pypes long tube header. Yes, this is technically classified as a 1 and 7/8ths inch header. But it's a little unique in that fact, as you are going to see a step design. And what does that mean? Well, the header is going to step up in size a little bit up until that three-inch collector. So, you're actually looking at a 1 and 3/4 inch diameter for the primary here for essentially about six to seven inches before it does step into the 1 and 7/8ths inch diameter, making up probably 75% to 80% of the header itself. And again, everything will end at that three-inch collector.Now, there is some functionality behind that step design. It's something that people have been doing for a long time in the world of hot-rodding with the goal of increasing your exhaust velocity as it moves through the system increasing your performance in the process. So, going back to what I said earlier about this header working for both the NA cars in addition to the forced induction applications, well this is why. Because you are seeing that smaller primary diameter here with the initial part of the header, that 1 and 3/4 inch diameter, which I think is ideal in the NA world before it does step into that larger primary. And again, that's where it's really going to shine for your forced induction applications. Very unique here with the Pypes header, and something I did want to point out.Now, all of these primaries have the CNC mandrel bend just for better flow, of course. You're not going to find any crushed bends or anything like that with these particular headers. They are finished off in this nicely brightly polished finish that you see here, which is a shame because these things do look really good on the table. You're not really going to see them once they're installed, unfortunately with the exception of a little bit by the flange here poking out through the engine bay.Also, something to look forward to here with the Pypes Long Tube Headers, they do have what they call their power-spike loaded into the actual collector here to help increase exhaust scavenging in addition to helping increase the exhaust velocity. As you remember, we talked about that a little bit earlier with the step design. Honestly, guys, this is something a lot of header manufacturers have been doing as of late with their Coyote long tubes, and it's something you can look forward to here with the Pypes option.Another important thing to point out here with the Pypes long tubes that we have in this video is that they are their off-road variety. Meaning you're not going o find any high-flow cats or anything like that. With these particular long tubes, they will deliver the biggest power and sound gains, but just be mindful of your local laws before pulling the trigger. Now, if you did want to find a Pypes long tube with a high-flow cat, we do sell a set here on the site. It is going to be a little bit more money with those included cats, but it is something to be aware of.Now, I do want to focus in on these three-inch connection pipes a little bit more here with the Pypes system because they are pretty unique to this system and will help you eliminate any neck-downs in your exhaust system. This is important to point out because using these guys will not work with a factory-style catback connection. You know what I'm talking about, right? The little neck-down that you're going to see with the factory catback, or maybe an aftermarket catback that utilizes that factory-style connection. These are just simply not going to work. Now, if you do have an after-market catback that does feature that neck-down, you spend a lot of money on it, and you really don't want to part with it, Pypes does offer a long tubes set up here on the site that will have the proper connection for what you need. Be sure to check that out here at AM if you wanted to do so.But of course we can't forget about the biggest reason people are interested in installing long tubes in the first place, and that is power gains or expectations when upgrading. And listen, guys, I'm gonna be brutally honest with you here. It's hard to put an exact number on what you can expect with your 2015 and newer Mustang because cars are different, dinos are different, mods are different, tunes are different. You get where I'm going with this. But with all that being said, it's not uncommon to see gains upwards of 10 to 20, even more, wheel horse-power when adding a long tube like this with a quality tune factored in. Forced-induction applications might even see a little bit more.Sticking with that tune, talk just a little bit further here, guys. Yes, these are an off-road long tube, meaning you will need to address for that in your custom tune. Otherwise, you're gonna see a "check engine light" pop up once the car's ECU realizes there's no longer any cats there. Listen, whenever you're doing a modification of this magnitude, it just makes sense to have your car tuned anyway because it's only going to maximize the potential of the mod itself. And if you already have a custom tune in place from some of the bigger name tuners out there, chances are they offer you a free revision with a new modification. Otherwise, they might charge you a small fee, but take my advice guys, it's definitely worth it. Switching gears, let's briefly cover the installation here. As you might imagine guys, this one will not be fun. Expect a full three out of three wrenches on the difficulty meter and at least a full day in the shop or garage, maybe more, depending on your level of expertise. As far as tools are concerned, well, you're going to need a bunch, right? A number of sockets, extensions, swivels, wrenches, the whole nine yards and of course, a lift will definitely make this install a lot easier. If you have to do it on your back on jack stands, well, God help ya.Now, I will say that if you've done a long tube install on a S197, you can look forward to a slightly easier day in the garage here with the S550 GT because, in our experience, there's just a little bit more room to maneuver. But either way, you will find two schools of thought on the actual installation process. I think most guys would prefer to support the engine or trans with a pull-jack or something similar, remove the mounts one at a time and tackle the job that way. On the other hand, you will find guys that prefer to just drop the entire front subframe and do the install that way. So, again, you have a couple of options here, but at the end of the day, if you don't really feel comfortable with tackling this job, don't be afraid to call your local shop. I'm sure they would really appreciate the business.Wrapping things up guys, I'm a big fan of the Pypes long tubes headers for the S550 GT, first and foremost because they're super affordable in the land of big-money brands. They're still going to give you that 304-grade stainless. The welds are still pretty decent, overall. And most importantly, they're gonna perform pretty much as good as any other long tube in the category for a fraction of the price. Just keep in mind, you have to use these with a three-inch connection for your catback. Guys, that's going to wrap it up. I'm out of here, but thanks for watching.
