Review & Install Video
Hey, guys, Stephanie with americanmuscle.com, here with a review of the Stainless Works long tube headers that come with an off-road X-pipe, available for 2011 to 2014 GT Mustangs. In this video we're going to be looking at a few different things in regards to this kit. We're gonna talk about the materials and construction of the headers and the mid-pipe, and the install, too. We'll talk more about this later, but I can tell you right now that long tube headers make for a difficult install, so I'm gonna call this one a three out of three wrenches in the difficulty meter. This kit from Stainless Works that includes long tube headers and a matching mid-pipe are going to be a good option for someone looking for a natural finish, off-road long tube header for both performance and sound gains. This kit comes with a matching shorty mid-pipe and makes way for a continuing three-inch catback. If we start with the heart of this kit, we'll be looking at the headers. Long tube headers are gonna offer both performance and sound gains, but the end result of your headers will depend on the rest of your setup. The runners on these particular headers are one and seven-eighth inch, which is slightly different than the one and three-quarter inch offering. Traditionally, you see forced induction cars running a larger runner and NA cars running a smaller runner, but I wouldn't really say that that's a hard and fast rule, especially with the Coyotes. So you don't have to have a blower to run a one and seven-eighths inch diameter, you just need to keep in mind your current mods and the goals that you have for your car when you're looking around, as well as what going with this size runner will do to your power band with the mods that you have. If you have some bolt-ons and you're still NA, you might see a hit on your low end torque. But once you spin the Coyote motor up, the larger diameter is gonna help keep things moving, so what you're gonna see are top end gains. Getting into the specifics here, these are a 304 stainless steel header that have a natural or raw finish, which is gonna be different than a chrome or ceramic coated header. It obviously doesn't have the polished appearance that a chrome header would have. While these don't have a ceramic coating either, they are made from that 304 stainless steel tubing, so you won't have to worry about corrosion. Not to mention you do get to see the beautiful welds since these have that raw finish. This is mandrel bent tubing, which is gonna help with smoother air delivery. The primary tubes then merge down into a three-inch collector, and then you have your mid-pipe right here which is an X-pipe. Typically speaking, we see X-pipes producing more of a louder, raspier sound than a deeper sound, especially when you compare it to the sound of an H-pipe. This mid-pipe is a three-inch mid-pipe, so just keep that in mind, too. If you guys didn't know already, when you change your header setup to a long tube setup, you also need to change your mid-pipe to a shorty mid-pipe to work with the long tubes. It's nice to see that these are already paired for you. It takes the guesswork out of the equation.If we move on to price, as we all pretty much know, or you'd know if you'd been shopping for long tubes, that they're pretty much gonna be a solid investment. They're pricey and they're difficult to install. This option from Stainless Works, since they are a higher quality item that's more at the top of the food chain, are gonna be on the more expensive side. The one and seven-eighths inch option that we have here are all gonna be slightly more expensive, which isn't unusual to see. You do tend to see larger runners costing more than smaller runners, but not usually by very much at all. You're looking at spending right about $1,400 for this kit, which does give you a little bit of a price break than if you were to buy these two pieces individually. But do keep in mind that you won't have to buy a shorty mid-pipe in order to install these since it already comes with the kit. This price tag is why I called long tube headers an investment earlier. You do have to keep in mind all the benefits and power that you'll be getting from this setup. To put things in perspective, it's not just Stainless Works that's gonna be expensive. You'll be looking at headers costing over $1,000 anyways. As for the install on this one, long tubes are always going to be a difficult install. I don't say this often, but if you don't have a helping hand or you don't have much experience, it might be better just to take the car to a shop for the install. If you do tackle this yourself, it's gonna be a full three out of three wrenches on the scale and a day in the garage, especially considering that you're gonna be installing this mid-pipe with the headers. You can do this on a jack and stands but a lift would make this easier, for sure. You're gonna need your toolbox for this one, with an assortment of different sockets, wrenches and extensions. You're looking at things like disconnecting the steering shaft, dropping the starter and removing a motor mount. 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, which is why you need to pull a motor mount on one side so you can raise the motor slightly with a jack to give you a little bit more room. Having a helping hand in this case is really gonna benefit you. A day of wrestling and some pretty pennies spent on these mods is totally worth it, in my opinion.Wrapping things up with the Stainless Works long tube off-road headers, these are a 304 stainless steel header that comes with a matching X-pipe for a mid-pipe, and both pieces are a full three-inch. The headers have one and seven-eighths inch runners. As usual, you can check them out more online for yourself right here at americanmuscle.com.
