Review & Install Video
I'm Ryan from extremeterrain.com, and this is my review and installation of the BBK Full-Length Headers with Y-Pipe and Catalytic Converters, fitting all 2007 to 2011 JKs that have the 3.8-liter V6. These are available with a chrome finish and, for a few dollars more, with a ceramic finish that's going to hold up really, really well. Today, we're gonna talk through the installation of these headers, which is a pretty in-depth, however, simple install that we are going to give two out of three wrenches. It is going to take you a few hours to get these installed, probably about three hours, but all you're going to need are your traditional hand tools and a little bit of patience. But we'll talk more about the install in just a second. We're also going to talk about the construction and a few of the features of this exhaust system.This header kit is designed to give you more power from your 3.8-liter V6. Having longer tubes before you get to the collector is designed to help the engine breathe a little bit better and help to get you a little bit of additional power. Along with that, the catalytic converters that come with this system are more of a high-flow cat, again, just allowing the engine to breathe better and have a little bit more power. Now, this isn't something that's going to be a complete night and day difference, but if you couple this with some other performance upgrades, especially if you go ahead and add some forced induction onto your JK, this is going to make a pretty big difference in power. If you have big tires on your JK and you're feeling like it's just slow off the line, this is probably not where I would go first to get that power back. I would go ahead and spend the money you were gonna spend on these on regearing the Jeep, get it back to a factory-like final drive. That's gonna give you a ton of power back. But again, if you are putting some other power adders on your JK, this may be a nice complement to those.These headers are made from inch and five-eighths mandrel-bent tubing, and essentially what that means is there's a piece that goes on the inside and the outside of the pipe, making sure that the pipe doesn't collapse as it's bent, giving you the most flow possible. As I said before, these are available in a chrome-plated or in a silver ceramic-plated finish. The ceramic is going to be about $100 more, but it's going to do a really nice job of holding up against rust and corrosion. Especially if you drive in an area where there's a lot of salt on the road in the winter, this ceramic is definitely going to be a good idea.These do also come with these high-flow cats, again, just adding a little bit of additional performance. These are going to include all of your hardware, all of your gaskets, all of your clamps and brackets that you're going to need to get them installed. So these are a direct fit replacement. These will work with the rest of your factory exhaust system without having to change out any of that. These also come with these O2 sensor extensions because, of course, with these full-length headers the bungs for the O2 sensors are going to be further from the engine, so you do have to extend the wiring harness a little bit. And this does come with the extensions, so you don't have to worry about adding anything there.As I said before, I am going to give this install a two out of three wrenches. It will probably take you around three hours to get these installed on your Jeep, assuming you don't have a ton of rust. If your Jeep is extra rusty, it may take a little bit more time. And we all know that exhaust systems are one of the first things that like to rust, so if you can spray down the nuts and the bolts with a good penetrating oil well before you get started. Of course, if you are going to be driving the Jeep, that oil is going to cook off, so you are going to have to keep reapplying. But that is definitely a good idea to help speed along the install. Now, the first step is going to be removing the rest of the exhaust system from the factory Y-pipe. Once that is disconnected, you can disconnect the Y-pipe from the factory headers and finally disconnect the factory headers from the block itself. You'll go ahead and attach your new headers and your new Y-pipe and finally connect the rest of the exhaust system to that new Y-pipe. So it is a very simple installation. There are some tight spots where you're going to need some extensions and some universals to get in there. However, it's not an overly complicated install. There are going to be a couple of different steps, and if you do have some rust, it can add some time. But other than that, just have your traditional hand tools and some patience, and you'll be able to get this bolted up in your driveway.There's no question that this is an expensive mod. The chrome-plated version's around $1,200, and the ceramic is about $100 more. And as I said before, if you're doing a lot of other power upgrades to your Jeep, especially if you've gone with forced induction, you are going to notice a change when you go with a full-length header kit like this. If you just bolt these up to your factory JK, I don't think you're going to see a huge improvement. You may feel a little bit of a change in the seat-of-the-pants dyno, but it's not going to be a huge night-and-day change. And for the price, again, if you're trying to get back power that you lost by adding a larger tire, I would rather see you take this money, put it into regearing, get back to a factory final drive, and then go from there. This is not going to be the first mod that I would go to to add power back to my Jeep, especially if I've done other mods, added big, large tires that's making it feel like it's down on power.So if you're looking to add some power to your JK, if you have a suite of other bolt-on power adders, this is going to be a nice complement to add even a little bit of additional power. These are going to be very well-built. They come with a really nice coating on them, which means they're going to last a long time, especially if you go with the ceramic coating, and they are a fairly easy bolt-on installation, although they are going to be a little bit pricey. So that's my review of the BBK Full-Length Headers with Y-Pipe and Cats, fitting all 2007 to 2011 JKs, that you can find right here at extremeterrain.com.
